Short circuit monitoring

The switch generates its own clock signal on the output lines FO1A/FO1B. Pay attention to this aspect when connecting to control systems and relays.

Category according to EN ISO 13849-1

Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

  • Category 4/PL e according to EN ISO 13849-1

Important: To achieve the stated category according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must always be evaluated.
