FC-35B Unipolar Voltage or Current to
Bipolar Voltage Signal Conditioner
Product Guide
The FC-35B is a DIN-rail or side-mount, selec-
table unipolar input to bipolar output signal
conditioner with isolation between input and
output, and isolation between 24-volt power
and input/output. The FC-35B field config-
urable isolated signal conditioner is useful in
eliminating ground loops and interfacing
sensors to PLC analog input modules. It trans-
lates unipolar voltage inputs or current inputs
to bipolar voltage outputs. The input and
output signal levels are selected via DIP
switches. In addition, the outputs can be either
a direct conversion of the inputs or an inversion
(a reverse acting operation). The user also has
the option of customizing the input OFFSET
(zero) and SPAN (full scale) adjustments that
can be set to a percentage of the full scale via a
pushbutton on the front panel.

Indicator Status Description
Diagnostic LED
Normal
Operation
The Diagnostic LED blinks at a propor-
tional rate to the selected input signal
level. This indicates that the unit is opera-
tional and functioning within spec.
Calibration
When performing field calibration or a re-
store to the factory calibration, the LED is
used for indication of the internal calibra-
tion process and will provide feedback (as
described under “User OFFSET and
SPAN Calibration) to the user if they have
selected an invalid input range.
User OFFSET and SPAN Calibration
Application adjustments to calibrate the input signal level:
1) Select the input and output signal modes via the dipswitches.
2) Connect 24 volt power to the signal conditioner.
3) Connect the mmiinniimmuumm(OFFSET) input signal level desired.
4) Move Switch 8 “CAL EN” to ON, press and hold the CAL pushbutton and
release after approximately 3 seconds. The DIAG LED comes ON steady
once pressed. If the pushbutton is held >3 seconds, the LED will turn off indi-
ating the User Cal feature is no longer available. The unit returns to normal
processing of input data and another press needs to occur to recapture the
input minimum value if a User Cal is desired. If the pushbutton is released in
<3 seconds, the minimum input value will not be captured and another press
needs to occur. If the push button is pressed longer than 10 seconds, the unit
will go into “Restore Factory Cal” mode.
5) If the input is within the user calibration, once the pushbutton is released at 3
seconds, the LED will flash 2-3 times. If the input is out of range, the LED will
flash several times rapidly. If the out of range occurs, the input needs to be
adjusted to the allowable range. In order to remove the User Cal, press and
hold the pushbutton for > 10 seconds.
6) Move the Switch 8 “Cal Ento OFF. Connect the maximum (SPAN) input
signal level desired and repeat steps 4 and 5.
7) Move Switch 8 “CAL EN” to OFF.
Restore Factory Calibration
1) Move switch 8 “CAL EN” to ON, press and hold CAL pushbutton.
Once the push button is held and released after 10 seconds, the LED
will flash several times indicating a valid restore has taken place. The
unit has now been returned to factory calibration. If the push button
is released before the 10 seconds has expired, the press will be
ignored and go back to regular signal processing based on previous
calibration coefficients.
2) Move Switch 8 “CAL EN” to OFF.
3) Start conversion with no power cycle required.
