LEUZE 547961 – MSI-TR2B-02 INDUSTRIAL SAFETY RELAY

Leuze MSI-TR2B-02 (547961) is a safety evaluation relay designed for compatible Type 2 single-beam optoelectronic protective devices according to IEC/EN 61496.

Key Technical Features:

  • Nominal 24 VDC supply voltage with ±20% tolerance.

  • Four digital switching inputs.

  • Two safety-related normally open relay outputs.

  • Three PNP transistor signal outputs.

  • Maximum continuous current of 2 A per safety-related current path.

  • External Device Monitoring (EDM).

  • Selectable Restart Interlock (RES).

  • Automatic or manual restart.

  • Periodic functional testing.

  • 20 ms response time.

  • 130 ms filter time.

  • 16-pole spring-cage terminal connection.

  • SIL 1, SILCL 1, PL c and Category 2.

  • Polyamide housing with IP40 ingress protection.

Applications: Type 2 single-beam safety sensor evaluation, industrial machine safeguarding, packaging equipment, automated production systems and conveyor safety control.

Safety Notice: The MSI-TR2B-02 is intended for compatible Type 2 protective devices. It is not a universal safety relay for every safety sensor or emergency-stop configuration. The achievable safety performance of a complete machine depends on the entire safety function design, installation and validation.
