Introduction
This chapter describes the SC-206X Series boards; lists the contents of your SC-206X Series kit;
describes the optional equipment and software support; and explains how to unpack your SC-206X
Series board.
The SC-206X Series consists of three digital signal conditioning boards (the SC-2060, SC-2061, and
SC-2062) you can use with the National Instruments data acquisition boards. The SC-2060 optically
isolated digital input board isolates digital signals received by data acquisition boards from the power
system of the host computer. The SC-2061 optically isolated digital output board isolates digital
signals sent by data acquisition boards used in systems that are isolated from the power of the host
computer. The SC-2062 electromechanical relay digital output board has eight electromechanical
relays controlled by digital output signals from the data acquisition boards. You can use the SC-206X
Series boards for digital signal conditioning on the Macintosh NuBus computers with the NB Series
and Lab-NB boards, the IBM Personal System/2 (PS/2) Micro Channel computers with the MC Series

Unpacking
Your SC-206X Series board is shipped in an antistatic package to prevent electrostatic damage to the
board. Electrostatic discharge can damage several components on the board. To avoid such damage
when handling the board, take the following precautions:
• When handling the board, use a ground strap or touch the antistatic package to a metal chassis that
is connected to each ground before removing the board from the package.
• Remove the board from the package and inspect the board for loose components or any other sign
of damage. Notify National Instruments if the board appears damaged in any way. Do not connect
a damaged board to your computer.
Chapter 2
SC-2060 Board
This chapter describes the SC-2060 board in detail including function, compatibility,
specifications, mounting, and connection.
With the SC-2060 optically isolated digital input board, you can easily connect field digital
signals to a computer equipped with a National Instruments data acquisition board. With the
appropriate SC-205X Series board, the SC-2060 can have input isolation for the National
Instruments data acquisition boards for the Macintosh II, IBM PS/2 Micro Channel, and
PC/XT/AT computers.
Each SC-2060 board has screw terminals for eight input channels. Each input screw terminal is
optically isolated from the digital I/O pins of the data acquisition board and from the other input
terminals up to a working voltage of 300 Vrms. This feature is useful in many situations,
especially in industrial and other monitoring environments where common mode voltages are
present.
Figure 2-1 shows the parts locator diagram for the SC-2060 board.

The 26-pin connector (J1) attaches to the appropriate SC-205X Series board via a 26-pin conductor
cable. You can connect an external +5 V power supply to the external power screw terminal block (J2)
if required. To determine if an external +5 V supply is necessary, refer to Internal or External Power
Selection in Chapter 5. Switch S1 selects either internal or external power. The buffer improves the
logic levels of the outputs from the optocouplers to the host data acquisition board. The optocouplers
isolate digital input signals connected to screw terminals IN0 through IN7 (on J3 through J10) from the
computer. The Vcc terminal of each pair (J3 through J10) of the contacts connects to the power
reference (Vcc) for the digital signal at the corresponding INx, where x represents any channel number
from zero through seven.
The digital input circuitry is positive logic; that is, a high input signal produces a high input state at the
host data acquisition board. The SC-2060 has eight channels of optocoupler input. For each channel,
the digital signal must connect to the channel screw terminals along with its voltage reference signal
(Vcc). The SC-2060 accepts many types of digital signals, including TTL, CMOS logic, and even
voltage references other than +5 V. However, the SC-2060 input circuitry must not carry more than 20
mA (that is, the difference between the voltage reference and the input signal at the terminals must not
exceed 8.4 V) to avoid damage to the board. You can add additional resistance in series with the input
circuitry to keep the current below 20 mA for voltage differences greater than 8.4 V. Figure 2-2 shows
the 5 V power circuit for the SC-2060 board. Figure 2-3 shows an equivalent circuit for the input
channels.

Warnings: When connecting or disconnecting signal lines to the screw terminals, you must power off
the lines. Potential differences between the lines and the SC-2060 ground create a shock
hazard while connecting the lines.
Connections, including power signals to ground and vice versa, that exceed any of the
maximum input or output signal ratings on the SC-2060 board can result in damage to any
or all of the boards connected to the SC-206X Series, to the host computer, and to the SC-
2060 board. National Instruments is not liable for any damages resulting from incorrect

A 26-pin ribbon cable connector connects the SC-2060 board to a digital I/O connector on an
SC-205X Series cable adapter board. The SC-205X Series board connects to the data acquisition
board with a 50-conductor or 100-conductor ribbon cable. You can connect the SC-2060 to any digital
I/O port on any SC-205X Series board. The digital I/O port that is connected to the
SC-2060 must be configured and operated on the data acquisition board as input only. For more
information on mounting and connection, see Chapter 5, Installation and Operation.

SC-2061 Board
This chapter describes the SC-2061 board in detail including function, compatibility,
specifications, mounting, and connection.
With the SC-2061 optically isolated digital output board, you can easily control field digital
signals from a computer equipped with a National Instruments data acquisition board. With the
appropriate SC-205X Series board, the SC-2061 can have input isolation for the National
Instruments data acquisition boards for the Macintosh II, IBM PS/2 Micro Channel, and
PC/XT/AT computers.
The SC-2061 board has eight output channels at its screw terminals that are optically isolated
from the computer up to a working voltage of 300 Vrms. You can use these boards in many
situations, especially in industrial and other control environments where common mode voltages
are present. The SC-2061 accommodates output signals that switch at rates up to 500 kHz.
Figure 3-l shows the parts locator diagram for the SC-2061 board.

The 26-pin connector (Jl) attaches to the appropriate SC-205X Series board via a 26-pin
conductor cable. You can connect an external +5 V power supply to the external power screw
terminal block (J2) if required. To determine if an external +5 V supply is necessary, refer to
Znternal or External Power Selection in Chapter 5. Switch S 1 selects between internal and
external power. The buffer improves the logic levels of the inputs from the optocouplers to the

The output channels are labeled OUT0 through OUT7 at the screw terminals. The SC-2061 has
three screw terminals per channel–GND, OUTx , where x is any channel number (0 through 7), and
+5 V. The lines between +5 V and GND indicate the boundary between channels.
The digital output of the SC-2061 is positive logic; that is, high output states from the data
acquisition board create high output at the screw terminals. The SC-2061 has eight channels of
optocoupler output. The digital output signal and its reference ground must connect at the screw
terminals. A +5 VDC power supply must also connect at the screw terminals. The digital output
signal must be pulled up. National Instruments recommends using a 4.7 kΩ resistor to the
+5 VDC line for the SC-2061. Because the output lines are open-collector lines, you must use
pullup resistors to obtain valid output from the board. Figure 3-2 shows the 5 V onboard
equivalent circuit for the SC-2061 board.

Warnings: When connecting or disconnecting signal lines to the screw terminals, you must power
off the lines. Potential differences between the lines and the SC-2061 ground create a
shock hazard while connecting the lines.
Connections, including power signals to ground and vice versa, that exceed any of the
maximum input or output signal ratings on the SC-2061 board can result in damage to
any or all of the boards connected to the SC-206X Series, to the host computer, and to
the SC-2061 board. National Instruments is not liable for any damages resulting from

The 26-pin connector (J1) attaches to the appropriate SC-205X Series board via a 26-pin
conductor cable. You can connect an external +5 V power supply to the external power screw
terminal block (J2) if required. To determine if an external +5 V supply is necessary, refer to
Internal or External Power Selection in Chapter 5. Switch S1 selects between internal and
external power. The driver amplifies the logic-level signals from the host data acquisition board
to levels sufficient to drive the relays. The relays open and close connections made at the screw
terminals (J3 through J10).
There are three connections per channel–NC, NO, and COM. There is a small gap between
screw terminal blocks of adjacent channels. Figure 4-1 shows the locations of the screw
terminals and other major board components.
The SC-2062 has eight sets of relay contacts. While a channel receives a low output signal, the
relay for that channel remains unenergized and the NC contact shorts to COM while the NO
contact remains open. When a high output signal is present on a channel, the relay for that
channel is energized, and the NO contact shorts to COM while the NC contact is open. A green
indicator LED just above each relay illuminates when the relay is energized. Each energized
relay requires about 60 mA, so power consumption goes up dramatically as the number of
energized relays increases. To reduce power consumption and to help extend relay life, control
the signals so that relays are energized for only the shortest periods of time and simultaneously a
minimal number of relays are energized. Figure 4-2 shows the 5 V onboard equivalent circuit
for the SC-2062 board.

Installation and Operation
This chapter describes the hardware installation, signal connections, and operation of the SC-206X
Series boards.
Hardware Installation
The following are general instructions for installing your SC-206X Series board in your computer data
acquisition system. Consult your computer user manual or technical reference manual for specific
instructions and warnings. Notice that the installation instructions are the same for each SC-206X
Series board.
1. Turn the host computer off before making any connections.
2. Install the SC-205X Series cable adapter board that is compatible with the host data acquisition
board you are using. Consult the SC-205X Series User Manual for instructions on the installation
of your SC-2050, SC-2051, SC-2052, SC-2053, or SC-2054 board.
3. It is advisable to use a 19 in. mounting rack or some other protective enclosure if you are using
the SC-206X Series board with high voltage. If you are not using high voltage, skip to Step 4.
Warning: The SC-206X Series boards are for use where high-voltage isolation is necessary or
desired. To ensure operator safety, these boards must be mounted in a suitable enclosure
if they are connected to circuits that may have high voltages (greater than 42 V peak).
The rack-mount kit alone with the acrylic plastic cover does not provide adequate
operator protection unless additional coverage is provided on the top and bottom.
Remember to turn the power off when making any connections to any of these boards,
unless the top and bottom are also covered to prevent unintentional contact with high
voltage wiring.
a. Your SC-206X Series board mounts on one-third of a 19-in. rack chassis. You can mount
two SC-206X Series boards alongside any SC-205X Series cable adapter board except the
SC-2054 board, which occupies half of the rack chassis. You can mount your SC-206X
Series board on the left side, in the center, or on the right side of the 19-in. rack mount as
shown in Figure 5-1.

Notice that the ground for the SC-206X Series board is connected to the metal standoffs
attached to the board. Rack mounting automatically grounds the board to the metal chassis.
• If you are planning to use more than two SC-206X Series boards with one SC-205X Series
board, double-height mounting within one rack-mount chassis is possible. You need a
hardware kit for double-height mounting (see Optional Equipment in Chapter 1). which
consists of two brackets that mount in the rack mount. You can mount a second row of SC-
205X Series and SC-206X Series boards on these brackets the same way you mount the first
row. Figure 5-3 illustrates double-height mounting.

4. Connect the external power lines to the SC-206X Series board (if required). See Internal
OY External Power Selection later in this chapter to determine whether external power is
required.
5. Connect the SC-206X Series board to the SC-205X Series board using type SC1 ribbon
cable.
6. Connect the field signals to the SC-206X Series board at the screw terminals.
7. Repeat steps three through five to install and connect any additional boards.
8. If desired, attach the appropriate cover to the rack mount. The optional 19-in. rack-mount
accessory (type DAl) kit includes a flat acrylic plastic cover. You install the cover by
sliding it over the rack-mount brackets and using the four screws included in the kit.
9. If the SC-206X Series board has an external +5 V supply, turn the power supply on now. A
red LED labeled PWR illuminates when the board is receiving power.
10. Turn the computer on.
11. When finished, turn off the computer before turning off any external power supplies for the
SC-206X Series board.

Internal or External Power Selection
Switch S1 on each SC-206X Series board selects internal or external +5 V power for that board. If you
set S1 to the position labeled INT, the host computer powers the SC-206X Series board via the host
data acquisition board. If you set S1 to the position labeled EXT, the SC-206X Series board is powered
from an external +5 V source connected to the J2 connector located near the J1 26-pin header.
In many cases, the host data acquisition board can supply enough power to run the SC-206X Series
boards. If the total +5 V power drawn by external accessories (such as the SC-206X Series boards, the
SC-2070 or SC-2071 boards, the AMUX-64T board, and SSR Series boards) exceeds the power
remaining, then some of these accessories must be powered by an external +5 V supply. Also, any
accessories connected to a DIO-32F board must be powered externally because this board does not
supply +5 V power. Table 5-1 shows the amount of power that each data acquisition board can supply
to external accessories.

Warning: Do not attempt to connect an SC-206X Series board to any connector
for which it is not designed. Incorrect connection can result in damage
to the SC-206X Series board and all components connected to the SC-
206X Series board, including the host computer. National Instruments
is not liable for any damages resulting from incorrect connections.
The SC-206X Series board operates on the digital port to which it is connected. For example, if you
want digital input isolation on Port B of a DIO-24 board, connect an SC-2060 board to an SC-2051
board at connector J4, labeled DIGITAL I/O, PORT -B-.
Operation
An SC-206X Series board operates on the 8-bit digital port corresponding to the label on its SC-205X
Series connection. To change the digital port that is being conditioned, simply disconnect the SC-
206X Series board from the current port on the SC-205X Series board and reconnect it to the desired
port. Power to the host computer and all external circuitry must be off while disconnecting and
connecting an SC-206X Series board.
Chapter 5 Installation and Operation
© National Instruments Corporation 5-9 SC-206X Series User Manual
Notice that the SC-2060 board has only input capability. Therefore, you must configure and operate
the digital port used with the SC-2060 board as only an input port. Likewise, the SC-2061 and SC-
2062 boards have only output capability. You must configure the digital ports used with either the SC-
2061 board or the SC-2062 board for only digital output.
When using an SC-206X Series board with an MIO-16 and SC-205X Series board, the 8-bit digital
port connected to the signal conditioning board consists of both port A and port B (4-bit ports) from
the MIO-16.
Note: For the MIO-16 boards, both port A and port B are used together as a single 8-bit port. Port A
bits 0 through 3 correspond to SC-206X Series channels 0 through 3 and Port B bits 0 through
3 correspond to SC-206X Series channels 4 through 7.
In this case, you must configure both 4-bit ports to match the operation of the SC-206X Series, that is,
input for the SC-2060 board or output for either the SC-2061 or SC-2062 boards.
Safety Information
! Caution: DO NOT OPERATE THE DEVICE IN AN EXPLOSIVE ATMOSPHERE OR WHERE
THERE MAY BE FLAMMABLE GASES OR FUMES.

Installation and Operation Chapter 5
SC-206X Series User Manual 5-10 © National Instruments Corporation
When using the device with high common-mode voltages, you MUST insulate
your signal wires for the highest input voltage. National instruments is NOT
liable for any damages or injuries resulting from inadequate signal wire
insulation. Use only 26-14 AWG wire with a voltage rating of 300 V and 60˚ C
for controlling 250 V. Prepare your signal wire by stripping the insulation no
more than 7 mm.
KEEP AWAY FROM LIVE CIRCUITS. When connecting or disconnecting signal
lines to the terminal block screw terminals, make sure the lines are powered off.
Potential differences between the lines and ground create a shock hazard while
you connect the lines.
Connect the signal wires to the screw terminals by inserting the stripped end of
the wire fully into the terminals. Tighten the terminals to a torque of 5-7 in.-lb.
Connections, including power signals to ground and vice versa, that exceed any
of the maximum signal ratings on the device can create a shock or fire hazard
or can damage any or all of the boards connected to the device and the host
computer, and the device itself. National Instruments is NOT LIABLE FOR ANY
DAMAGES OR INJURIES resulting from incorrect signal connections.
Clean devices and terminal blocks by brushing off light dust with a soft,
nonmetallic brush. Remove other contaminants with deionized water and a
stiff nonmetallic brush. The unit must be completely dry and free from
contaminants before returning to service.

Propagation Delay, Pulse-
Width Distortion and
Propagation Delay Skew
Propagation delay is a figure of
merit
which describes how
quickly a logic signal propagates
through a system. The propaga-
tion delay from low to high (t&l
is the amount of time required for
an input signal to propagate to
the output, causing the output to
change from low to high.
Similarly, the propagation delay
from high to low (t& is the
amount of time required for the
input signal to propagate to the
output causing the output to
change from high to low (see
Figure 8).
tions where synchronization of
signals on parallel data lines is a
concern. If the parallel data is
being sent
through
a group of
optocouplers, differences in
propagation delays will cause the
data to arrive at the outputs of the
optocouplers at different times. If
this difference in propagation
delays is large enough, it will
determine the maz&num rate at
which parallel data can be sent
through the optocoupleti.
Pulse-width distortion (PWD)
results when tpm and tpnL differ ti
value. PWD is defined as the
difference between tpLH and trm
and often determines the
maximum data rate capability of a
trammission system. IWD can be
expressed in percent by dividing
the PWD (in ns) by the minimum
pulse width (in ns) being
transmitted. Typically, PWD on
the order of 20-30% of the
minimum pulse width is tolerable;
the exact figure depends on the
particular application (RS232,
RS422, T-l, etc.).
Propagation delay skew is defined
as the difference between the
mlnimumand~um
propagation delays, either tpm or
tPHL, for any given group of
optocouplers which are operating
under the same conditions (i.e.,
the same drive current, supply
voltage, output load, and
operating temperature). As
WstmtedinFigure19,ifthe
inputs of a group of optocouplers
are switched either ON or OFF at
the same time, tpss is the
difference between the shortest
propagation delay. either tPr,n or
tmL, and the longest propagation
delay,
either tpm or tpnk
As mentioned earlier, tBK can
determine the maximum parabel
data uammission rate. Figure 20

the clock and the data lines being

Propagation delay skew, tpsk, is

SC-206X Series User Manual A-20
signals at the inputs and outputs
of the optocouplers. To
obtain
the
maximum data transmission rate,
both
edges
of the clock signal are
being used to clock the data; if
only one edge were used, the
clock signal would need to be
twice as fast.
Propagation delay skew repre-
sents the uncertainty of where an
edge might be after being sent
through an optocoupler. Figure
20 shows that there will be
uncertainty in both the data and
the clock lines. It is important
that these two areas of uncertainty
not overlap, otherwise the clock
signal might arrive before aU of
the dam outputs have settled, or
some of the dam outputs may
start to change before the clock
signal IIS arrived. From these
considerations, the absolute
minimumpulsewidththatcanbe
sent through optocouplers in a
paraM application is twice trsK- A
cauti?~,
design should use a
slightly longer pulse width to
ensure that any additional
uncertainty in the rest of the
circuit does
not
cause a problem.
The trsir specified optocouplers
offer the mtages of
guaranteed specifications for
propagation delays, pulsewidth
distortion and propagation delay
skew over the recommended
temperature, input current, and
power supply ranges.
