1. General instructions
• Disconnect power prior to installation
• Installation only by Qualified personnel
• Follow all applicable local and national electrical codes
• Due to potential hazardous voltages in close proximity, use a nonconductive tool and proper PPE when adjusting the potentiometers
on the front panel.
For applications with high isolation voltages, take measures to prevent
accidental contact and make sure that there is sufficient distance or insulation between adjacent devices!
Appropriate safety measures against electrostatic discharge
(ESD) should be taken during assembly and adjustment work on
the 931S-T9C2D-DC.
2. Application
The 3 Way Universal Thermocouple Conditioners 931S-T9C2D-DC are
used for galvanic isolation and conversion of thermoelement signals. Input
and output signals are factory set according to type or can be calibrated/
switched via DIP switches. It is not necessary to adjust the measurement
range. A +/- 5% variation can be achieved in the respective range by
connecting potentiometers for zero and span. The transmitted
measurement signal is linear to be measured temperature.

3. Configuration
3.1 Equipment
A screwdriver with a width of 2.5 mm is required to adjust the unit and to
connect the wires to the terminals.
3.2 Opening the unit
Disconnect the plugs. Disengage the top part of
the housing by carefully pressing the latches on
both sides (1). Pull out the top part of the housing and the electronics section until they unlock
(2).
3.3 Settings
Set input and output ranges, minimum input
values and measuring span via the DIP switches
SW1 and SW2 according to the following tables.
When activating variable setting SW 1/8 of the
span or offset, it is possible to make additional
adjustments via front potentiometers span and
offset, accessible below cover (3).

Should a temperature measurement range be selected that is larger than
the specified range of the thermocouple used, then the module sets itself
to the maximum specified range:
Type K –200º C … +1372º C
Type J –200º C … +1200º C
Type T –200º C … +400º C
Type E –200º C … +1000º C
Type N –200º C … +1300º C
Type R –50º C … +1760º C
Type S –50º C … +1760º C
Type B +50º C … +1820º C
The voltage output and the combined current output (0…20 mA and
4…20 mA) are routed from two separate, calibrated connections.
The output selected via the DIP switch, is the only output that is calibrated.
