1 General information
The modules are equipped with 2 safe analog input pairs for current measurement. Each input pair has its own
sensor power supply. The channels with their respective sensor supplies are galvanically isolated from each other.
It is possible to acquire current signals in the range of 0.5 to 25 mA.
The safe analog input modules are suitable for safely acquiring current signals for safety-related applications up
to PL e or SIL 3.
These modules are designed for X20 16-pin terminal blocks.
