24VDC safety relay extension module with 5 N/O & 1 N/C force-guided contacts. Delivers Cat. 4 PL e (EN ISO 13849) safe isolation within a compact 35mm profile.
The Phoenix Contact 1442021 (PSR-SCP- 24DC/URM4/5X1/2X2) is an industrial-grade safety relay extension module designed to enhance the securing of critical automation systems. Measuring a compact 35mm in width, this module delivers robust 1-channel or 2-channel contact extension capabilities, featuring five normally open (N/O) contacts, one normally closed (N/C) contact, and one confirmation current path. Engineered to meet the rigorous Category 4 PL e safety isolation standards per EN ISO 13849, the device seamlessly integrates with basic master safety controllers to expand output capacity without sacrificing safety integrity. It utilizes pluggable screw terminal blocks for rapid installation and maintenance, with force-guided electromechanical contacts ensuring highly reliable operation over a mechanical lifespan of up to 10 million cycles. Operating on a 24 V DC input voltage range, this safety module is an essential component for safeguarding high-risk machinery in manufacturing and process industries.

Expands the safety outputs of a primary safety controller in automated robotic work cells, allowing a single E-Stop input to safely isolate power across multiple independent robot arms and conveyors simultaneously.
Overcomes the limited number of safe output channels on a master safety controller without compromising the strict Category 4 PL e safety rating.
Integrates with a master light curtain relay to extend safety outputs to hydraulic press drives, enabling redundant interruption of control power and preventing machine motion when the protective field is breached.
Ensures safe electrical isolation of high-risk machine drives by providing reliable 5 N/O force-guided contacts for disconnecting multiple power sources synchronously.
Utilized in chemical or process automation to multiply safety relay outputs, securely shutting down pumps, closing isolation valves, and activating alarms simultaneously during an emergency trip event.
Provides a reliable, synchronous disconnect across diverse electromechanical actuators requiring isolated, potential-free safe contacts during a critical process shutdown.
