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.
