Product information

Description

The Phoenix Contact PSR-SCP-24UC/THC4/2X1/1X2 is a high-performance safety relay specifically engineered for two-hand control applications. Operating on a 24V AC/DC supply, this module is designed to ensure maximum operator safety in industrial automation environments. It provides reliable monitoring and switching functions, making it an essential component for safety-critical systems where precise control is required to prevent accidental machine activation.

Advantages

This safety relay offers exceptional reliability by supporting two-hand control devices in accordance with EN 574 type IIIC standards. It is capable of achieving high safety integrity levels up to SIL 3 and meets the requirements for Category 4 and Performance Level e as defined by EN ISO 13849. The device features advanced synchronous activation monitoring, which ensures that both control inputs are operated within a specific timeframe, thereby preventing bypass or tampering with the safety mechanism.

Suitable for

  • Two-hand control systems for machinery
  • Industrial automation safety circuits
  • Emergency stop and safety interlock integration
  • Applications requiring SIL 3 or Cat. 4, PL e compliance

When it may not be suitable

This relay is specifically optimized for two-hand control configurations and may not be suitable for general-purpose switching applications or systems that do not require synchronous input monitoring. It is not intended for use in environments exceeding its specified voltage or environmental ratings.

Key specifications

  • Operating voltage: 24V AC/DC
  • Safety standard compliance: EN 574 type IIIC
  • Safety integrity: Up to SIL 3, Cat. 4, PL e
  • Functionality: Synchronous activation monitoring

How to use

The relay should be installed within a control cabinet on a standard DIN rail. Connect the two-hand control buttons to the designated input terminals, ensuring that the wiring complies with the relevant safety standards for two-hand control devices. The power supply must be connected to the specified 24V AC/DC terminals. Once installed, the device monitors the simultaneous activation of the inputs; if the inputs are not triggered within the required synchronous window, the relay will prevent the machine from starting or will initiate a safe stop.

What to consider before purchase

  • Verify that your control system requires two-hand safety logic
  • Ensure your power supply matches the 24V AC/DC requirement
  • Confirm that the safety level (SIL 3/PL e) meets your machine risk assessment
Usage recommendations: Always perform a functional safety test after installation to ensure the synchronous monitoring operates correctly according to your specific machine safety requirements.
