Phoenix Contact 2902726

The PSR-SPP-24DC/MXF1/4X1/2X2/B safety relay operates at a nominal input voltage of 24 V DC, with a permissible input voltage range of 0.85 to 1.1 times this nominal value. It supports typical input currents of 125 mA when relays are actuated, and 55 mA in two-channel configurations without actuation.

This relay integrates four normally open (N/O) contacts, two semiconductor alarm outputs, and is equipped with a pluggable Push-in terminal block. It offers three safety functions and two shutdown levels, facilitating both automatic and manual monitored activation. The relay also features a maximum switching frequency of 0.5 Hz and a mechanical service life rated at 10 million cycles.

With dimensions of 22.5 mm in width, 117.4 mm in height, and 114.5 mm in depth, this device is suitable for installation on standard DIN rails. The ambient operational temperature ranges from -20 °C to 45 °C, while the storage and transport temperature can vary from -25 °C to 85 °C. The relay's design adheres to multiple standards, including DIN EN 50178/VDE 0160, ensuring reliable performance in demanding environments.
