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 (F01A and F01B) must be evaluated.
