Input Module
Functions:
Processing inputs from various safety sensing devices.
Assignment of sensing inputs to output switching groups by means
of redundant rotary coded switches: one set selects the input
function, the other set selects the output group.
Inputs: 2 inputs for single-, dual- or three-channel activation.
A solid-state switch on-off signal input from a light curtain and an
on-off signal input from safety contacts (switch or
electromechanical relay) input can be given as inputs to the same
Input Module.
Rotary switches on the right side of the MSR320 Input Module. One rotary switch selects
the function of the Input Module (see functions list below), the other assigns an Output
Group (Module) assigned to this Input Module.

Two switches per selection have been provided for redundancy.
Both sets of rotary switches of one input module must be set
identically.
