Connecting the AI111.0 Inputs

The module AI111.0 allows to measure three temperatures, voltage (0...10V) and current (0/4...20mA).
The diagram below shows the block diagram and wiring of the analog input module.
It is possible to connect up to two AI111 modules to the UMC100.3. Connect the Adr terminal to 24V DC at the
second module.
Avoid parallel runs of power cables or other noise sources to the analog input signal cables. It is recommended to
use shielded cables (see technical data).
