3.4 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, 
safety transmitters or wired contacts. Two-wire or three-wire transmitters with a maximum 
supply current of 30 mA can be connected to the input module. 
The functional units are electrically isolated to ensure that the input signals are non-
reactive.  
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. 
The module is equipped with LEDs to indicate the status of the digital inputs, see Chapter 
3.4.2.
