Phoenix Contact PSR-SCP Coupling Relay, 24V dc, 3 Safety Contacts

PSR Safety Relays for the Process Industry

The PSR range of failsafe safety relays from Phoenix Contact are used as standard within process engineering.
The use of safe coupling relays for power adjustment and the electrical isolation of actuators is gaining in importance, as actuators often need more current or other voltages than the controllers are able to supply. The digital outputs of thecontrollers run automatic self-tests at regular intervals in order to detect faults. Regardless of this, the test pulses involved usually cause premature wear of the relays. With their integrated test pulse filter and control circuit to adjust power consumption, all FSP devices take these special requirements of a failsafe controller into account.
