SIL3-Certified Coupling Relay for Fire and Gas Applications
- Published: Monday, 29 October 2012 11:46
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.
