Phoenix Contact PSR-SPP-24UC/ESAM4/8X1/1X2 2963996
Safety Relay | 24 V DC Supply | 8 Safety Enabling Paths | 1 Signaling Path | Emergency Stop & Safety Door Monitoring
Product Detailed Description
The Phoenix Contact PSR-SPP-24UC/ESAM4/8X1/1X2 (2963996) is an electromechanical safety relay from the PSRclassic product family. It is designed for emergency-stop circuits and safety-door monitoring in industrial machinery and automation systems. The relay supports single-channel and dual-channel control and provides eight safety-related enabling current paths, plus one non-safety signaling path for status feedback. It supports safety applications up to SIL 3 and Category 4, Performance Level e, when used in a properly designed and validated safety system. The unit operates on a 24 V DC supply, mounts on a DIN rail, and uses pluggable Push-in terminal blocks for convenient wiring.
