Scope of Delivery

The module must be installed on a suitable connector board to be able to operate. If a Field

Termination Assembly (FTA) is used, a system cable is required to connect the connector board

to the FTA. Connector boards, system cables and FTAs are not included within the scope of

delivery.

The connector boards are described in Chapter 3.6. the system cables are described in

Chapter 3.7. The FTAs are described in own manuals.

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.
