Fields Description
10V Attenuator This check box allows you to set ‘Input High’ and ‘Input Low’ values in the
software in volts up to 10 V.
Note: The 931U-C9A2C-OP will only accept values up to 10 V if the attenu-
ator switch on the main board is set to the 10 V setting. If you change the
switches you must recalibrate the voltage input.
Burnout Sets the action in case of sensor burn-out or disconnection. Upscale sends
the output to 22 mA, downscale sends the output to 3.7 mA.
Type Allows you to choose between thermocouple or RTD types. Not shown for
other input types. Note: you can set up your own linearisation tables here by
choosing ‘user defined’.
Input connection Is the input connected in two, three or four wire mode. For RTD and resist-
ance inputs only. Sets up the lead length compensation.

Fields Description
Range Sets the output range, normally 4.00 mA to 20.00 mA.
Transfer function X 1 gives the usual proportional output.
Output action Set to direct or reversed. Direct gives the usual proportional output. For
reversed action, the input low value gives a 20 mA output and the high value
a 4 mA output.
