The module includes four analog inputs and four temperature inputs. Depending on the used variant, the analog input accepts currents from 0/4 mA up to 20 mA and different temperature sensor types and ranges.
For each analog input a terminal with separate ground and +24V (from the bus for sensor supply) is available. Aditionally for the temperature inputs a separate ground for a shield is supported.
The module provides a separate analog ground. The shield can be connected to the bus ground via connecting the two terminals (if sufficient) or can be connected to the earth in your system (recommended).
