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.

Line Control

The digital outputs DO 1 through DO 8 of the DIO 24/16 01 module can be used to monitor

the own digital inputs or the digital inputs of other modules (e.g., DI 32 01) for short-circuits

and open-circuits, e.g., for an EMERGENCY STOP button complying with Cat. 4 in

accordance with EN 954-1. To this end, the outputs are pulsed and connected to the

safety-related digital inputs. In this case, the outputs assume the function of pulsed outputs.
