Assembly

The module has 32 analog current inputs (0/4…20 mA), each input is measured and functionally

tested using two internal measuring facilities. A short-circuit-proof transmitter supply is assigned

to each input.

The 32 analog inputs can be used to evaluate the values measured for the transmitters and

safety transmitters. Two-wire or three-wire transmitters with a maximum supply current of 30 mA

can be connected to the module.

The functional units are galvanically separated to ensure that the input signals are interference

free.

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.
