Analog Input
Make sure the Analog jumpers support the software setting; see Analog Input Module on page 367
for jumper settings.
Current
To connect channel A1 with a 2-wire shielded cable, connect the positive wire to A1+, the negative
wire to A1-, and optionally the shield to GND.
If you have the positive/negative wires reversed, the output will always read 0 (zero).
Voltage
To connect to Channel A1 with a 2-wire shielded cable, connect the positive wire to A1+, the
negative wire to A1-, and optionally the shield to GND.
If you have the positive/negative wires reversed, the polarity of the voltage will be reversed.
