OSSDs (Output Signal Switching Devices)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 outputsA feedback loop can be connected directly to the SOM. Depending on the parameter settings, further inputs and outputs can also be used.
