ANALOG IN 15 BIT VOLTAGE/CURRENT 8CH IC220ALG221
Current Loops
If the ANALOG IN 15 BIT VOLTAGE/CURRENT
8CH terminal is used to measure currents in cur-
rent loops, please ensure that the eight current
inputs operate on a common ground potential
(single-ended). Thus, the measured input
should always be on the GND potential with the
minus input.
