Product Details
Schmersal Safety Relay, 1 Auxiliary Contact, 24 V AC/DC - SRB-E Series - SRB-E-301ST
This multi-functional safety relay from Schmersal monitors two local sensor circuits at the same time. It frees up space on your control panel by reducing the number of individual units needed. Screw connections and a plug-in design make it simple to wire and install. The innovative relay reacts separately to each sensor circuit, so it individually switches off machinery or equipment when a fault is registered for enhanced system safety. Its ventilated housing keeps the unit's operating temperature low to improve its overall efficiency. Use relays like this for monitoring safety doors or light grids.
