SIL3-Certified Coupling Relay for Fire and Gas Applications

Press Release   •   Oct 29, 2012 09:00 GMT

With its PSR-ETP coupling relay, Phoenix Contact is offering a power adaptation module with electrical isolation specifically designed to address the requirements of the process industry. This is because, in addition to safety-related interruption of circuits, safe switch-on is becoming increasingly more important. The relay is certified according to SIL3.

The integrated test pulse filter and the adapted current control circuit guarantee a long service life and ensure that the relay is compatible with the different safety-related systems.

The optional line/load monitoring feature supports load-dependent configuration and allows unified diagnostics from the control system to the actuator. The existing wiring is used to signal a wire breakage or loads that are missing or incorrect. This means that additional installation costs and additional digital inputs to read back the actuator state can be eliminated.
