Analog Inputs
Shields should be connected at the signal source.
Inputs may be set as either thermocouple, current, or voltage. To set an input:
-
Use the appropriate wiring as shown below.
-
Open the device and set the jumpers according to the instructions beginning on page 6.
The adapter and the COM signals of the analog inputs must be connected to the same 0V signal.
The COM signals of each channel are internally shorted.
When set to current/voltage, each 2 inputs share a common COM signal.
