Product description

Original Phoenix Contact safety relay type PSR SCP 24DC ESD 5X1 1X2 300 with integrated time delay. It safely monitors and disconnects safety-related circuits such as emergency stop, safety doors or two-hand controls.

The front carries LED status indicators for Power and relays K1, K2, K3(t) and K4(t). The time delay is set in several steps via the front rotary switch, and a selector switch chooses operating mode A or B. The wiring diagram printed on the housing side shows the internal contact logic with delayed and instantaneous safety contacts. Used, tested and fully functional, technically flawless, with signs of use as shown in the photos.
