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.

Features and Benefits

• Slim overall width means you can save space
• Fast installation and startup
• Force guided contacts make them a reliable choice
• Verified safety

Failsafe controllers are used as standard in process engineering. In this context, the use of safe coupling relays for power adjustment and the electrical isolation of actuators is gaining in significance, as actuators often need more current or other voltages than the controllers are able to supply. Furthermore, the digital outputs of failsafe controllers run automatic self-tests at regular intervals in order to detect faults. However, 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.
