The PSR-SCP-24DC/SSM/2X1 safety relay, ordered as 2981567, is designed for safety circuits meeting EN 61508 SIL 3 and EN 954-1 Cat. 4. It monitors two PNP or 2-wire proximity switches and provides two positively-driven N/O contacts rated for 250 V AC/DC and 5 A continuous current, with silver nickel contacts hard gold-plated. Operating on 24 V DC (range 20.4-26.4 V), it has a response time of 12 ms and release time of 8 ms. Downtime detection functions at frequencies below 2 Hz. Status LEDs indicate power, mode, and output state. The relay measures 22.5 × 99 × 114.5 mm, mounts on a DIN rail, and uses screw terminals for 0.2-2.5 mm² conductors. It complies with TÜV approval and requires installation in a closed control cabinet.
