Assembly

The input module has 16 safety-related digital inputs 48/120 VAC for contact makers. For

safely detecting a high level on the digital input, the voltage and current thresholds must be

exceeded, see Table 8.

The 8 short-circuit-proof supplies feed 2 supply outputs each (S1 to S8). One supply output

is assigned to each digital input.

The safety-related 1oo2 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.
