AS-Interface Safety at Work safe output SOM

  • 1 redundant OSSD
  • Control by SMOx/GMOx
  • Control by machine control
  • Up to 4 inputs
  • Diagnostics via AS-Interface


The OSSD is of redundant design according to category 4 EN ISO 13849-1. Safety-related control is via the bus by a suitable monitor, for example by a GMOx or SMOx. Operational switching is also possible directly by the control system with appropriate parameter settings.

Inputs and outputs

A feedback loop can be connected directly to the SOM. Depending on the parameter settings, further inputs and outputs can also be used.
