Safety Function

The module is equipped with safety-related inputs and outputs.

Safety-Related Analog Inputs

Each group of 8 inputs is provided with a common, short-circuit-proof supply LS+ on the

clamps.

The safety-related application (SIL 3 in accordance with IEC 61508) of the inputs and the

sensors connected must comply with the safety requirements. For more information, refer

to the HIMatrix Safety Manual.

Reaction in the Event of a Fault

If the module detects a faulty signal on a digital output, the affected module output is set to

the safe (de-energized) state using the safety switches.

If a fault in the module occurs, all digital outputs are switched off.

In both cases, the module activates the FAULT LED.

The error code allows the user to configure additional fault reactions in the user program.
