Description
The FC-33 is a DIN rail mount, selectable input / output signal conditioner
with 1500VDC isolation between input and output and1500VDC isolation
from 24 volt power and input / output. The field configurable input/output
types allow a wide ranging capability for 0 - 5V, 0 - 10V , 0 - 20mA ,
4 - 20mA .
The FC-33 has user selectable factory-calibration, but also has OFFSET
(zero) and SPAN (full scale) adjustments of the input signal.
The OFFSET (zero) has an adjustment range of 0 to 25% of full scale
input, the SPAN (full scale) has an adjustment of 80 to 102%
Application
The FC-33 field configurable isolated input/output signal conditioner is
useful in eliminating ground loops and interfacing sensors to ourPLC
analog input modules. The FC-33 has 3 way isolation, this feature solves
many types of configuration problems. For example, the signal
conditioner can be configured for sinking input andsourcing output. It
also allows signal translation from current input to voltage output or
voltage input to current output.
This feature would be useful when you have limited type and number
of channels in your system design, i.e. 8 channels of 4-20mA , 7 which
are used and one transmitter that is 0 - 10V .
LEVEL LED
This LED is a powerful tool when setting up the signal conditioner.
During normal operation the LED will blink at a proportional rate to the
selected input signal level. When performing field calibration the LED is
used for indication of the internal calibration process.
CAL - Pushbutton
Thispushbutton along with various switch settings, allows you to
calibrate the signal conditioner for your application or restore factory
default calibration.
DC Selectable Input, Isolated Signal Conditioner
FC-33Input Selection
The signal conditioner can be configured for either DC milliamps or
DC volts. Input and Output signal types are 0 - 5V, 0 - 10V, 0 - 20mA ,
4 - 20mA .
Adjustments
The FC-33 has built-in self-calibration, but also has
OFFSET (zero) and SPAN (full scale) adjustments of the
input signal. If your application requires, different
span or offset (i.e. 3.6mA offset and
adjust accordingly.
Application adjustments
Calibrating the input signal level -
1. Select the signal range (i.e. 4 - 20mA ).
2. Connect 24 volt power to the signal conditioner.
3. Connect the minimum input signal level.
4. Turn Switch2 ON, press and hold the CAL
pushbutton until the LEVEL LED comes ON steady
(approx. 3 seconds), then release immediately. If the
pushbutton is NOT released while the Level LED is ON
steady, the signal conditioner will return to factory
calibration.
5. Repeat above sequence for maximum input signal.
6. Turn Switch 2 OFF.
To return to factory calibration-
1. Turn switch2 ON, press and hold the CAL
pushbutton until the LEVEL LED comes ON steady and
then starts flashing (approx. 10 seconds), then release
the pushbutton. The unit has now been returned to
factory calibration.
2. Turn Switch2 OFF.
