2981428 Phoenix Contact PSR-SCP-24DC/ESD/5X1/1X2/300 Safety Relay

Product Overview:

The 2981428 phoenix contact PSR-SCP-24DC/ESD/5X1/1X2/300 from Phoenix Contact is a strong safety relay that is meant for important tasks including emergency stop circuits, safety door monitoring, and light grid evaluation in industrial automation and maritime equipment installations. It may work with one or two channels and has automatic or manual reset modes. It has three normally open (N/O) enabling contacts, one normally closed (N/C) signaling contact, and two N/O contacts with configurable dropout delays from 0.2 to 300 seconds in 24 exact stages.

This 24 V DC relay is built for maximum safety and meets the EN ISO 13849-1, IEC 61508, and EN IEC 62061 requirements for undelayed pathways and Cat. 3/PL d for delayed ones. With its small DIN-rail design (45 mm wide), force-guided contacts rated for 10 million cycles, LED status indicators, and seals that can’t be tampered with (like PSR-ESD-300), it’s perfect for high-reliability control panels that need surge protection up to 6 kV and easy integration.

Key Features and Benefits of 2981428 phoenix contact:

This safety relay can work with one or two channels and can be turned on automatically or by hand, making it easy to add to industrial control systems. It has three normally open (N/O) undelayed contacts, one usually closed (N/C) contact, and two N/O contacts with a dropout delay that can be changed from 0.2 to 300 seconds in 24 steps. Protective labels (PSR-ESD-300) or electronic manipulation protection (PSR-ESD-30) are further safety features that make the product more reliable in tough situations.
​

• For flexible output setups, there can be a maximum of 3 undelayed and 2 delayed enabling contacts.
• Supports the examination of light grids, emergency stops, and doors.
• Electromechanical relay with force-guided contacts that can handle 10 million mechanical cycles according to IEC/EN 61810-3.
• LED status displays show the operating voltage and make it easy to diagnose problems.

Applications in Industrial Automation:

This Phoenix Contact safety relay is great for marine equipment, industrial automation, and control panels. It works best in places where strong emergency stop circuits and safety door features are needed. It has two-channel control and cross-circuit detection, which makes it safe for high-risk machinery and meets the standards set by EN ISO 13849-1, IEC 61508, and EN IEC 62061. People who work in fields like manufacturing and marine technology benefit from its ability to be mounted on DIN rails and resist vibrations (10–150 Hz, 2g).
