Structure

The module has 64 digital inputs (24 V) for digital signals, contact makers and proximity

switches (two-wire). For safely detecting a high level on the digital input, the voltage and

current thresholds must be exceeded (see Table 8).

The eight short-circuit-proof supplies feed eight supply outputs each (S1+ to S8+). One

supply output is assigned to each digital input.

The processor system for the I/O module controls and monitors the I/O level. The data and

states of the I/O module are made available to the processor modules via the redundant

system bus. The system bus has a redundant structure for reasons of availability.

Redundancy is only ensured if both system bus modules are inserted in the base plates

and configured in SILworX.
