3.4 Structure
The module has 32 analog current inputs (0/4...20 mA), each input is measured using an
internal measuring facility. 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 module.
The functional units are electrically isolated to ensure that the input signals are non-
reactive.
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.
The module is equipped with LEDs to indicate the status of the analog inputs,
see Chapter 3.4.2.
