Phoenix Contact 2700564

The PSR-MC50-3NO-1DO-24DC-SP safety relay is specifically engineered for monitoring non-equivalent signal generators, achieving a Safety Integrity Level (SIL) of 3 in compliance with Category 4 and Performance Level e standards. This device operates on a 24 V DC supply and supports two-channel configurations, allowing for both automatic and manual monitored starts.

With three enabling current paths, the relay facilitates a typical response time of less than 175 ms during automatic start conditions. It incorporates force-guided contacts in accordance with IEC/EN 61810-3, ensuring safety through its electromechanical relay design. The rated control supply current is approximately 80 mA, and it features a maximum power dissipation of 4.8 W under nominal conditions.

The device is designed for industrial applications, offering a rated insulation voltage of 250 V AC and a degree of protection rated at IP20. Additionally, it operates effectively across a temperature range of -40 °C to 55 °C, making it suitable for various environmental conditions. The housing is constructed from PA material and features a compact size, measuring 12.5 mm in width, 116.6 mm in height, and 114.5 mm in depth. For ease of installation, it utilizes a pluggable Push-in terminal block.
