safety processing units


All safety light barriers with an OSE-signal or in some cases additionally 8k2 resistor contact strips can be connected to the safety processing units. These are evaluated and then provide a switching function in the form of a potential-free contact. This is often necessary with older controls, as these lack a direct interface for the analysis of the OSE-safety-signal.

The safety processing unit can typically be used for upgrading older systems.

The safety processing units of the AOS-series were developed in accordance with ISO 13849-1 "Safety-orientated components of controls".
