The safety relay from Phoenix Contact, model PSR-SCP-24DC/FSP/2X1/1X2, is a highly advanced device designed for SIL 3 high- and low-demand applications. It serves to safely couple digital output signals to the periphery and provides a reliable solution for safety-critical applications. With a response time of 50 ms and a fallback delay of 1 s, it ensures precise control. The relay is equipped with two release current paths and a signaling contact, facilitating the implementation of safe-state-off applications. Installation is straightforward on a DIN rail, and the polybutylene terephthalate (PBT) housing ensures durability and robustness. With a mechanical lifespan of up to 10 million cycles, this safety relay is a reliable choice for demanding applications.

Forced-guided contacts according to EN 50205 for enhanced safety. Integrated test pulse filter for easy proof tests according to IEC 61508. Couples digital output signals from fail-safe controls for galvanic isolation. Width of only 17.5 mm for space-saving installation. RoHS compliant and suitable for a temperature range of 20 - 55 °C.
