Product Description Ordering Key
RA 23 25 H 06 NO S
The system monitoring solid state relay (sense relay) pro- vides an alarm output in the event of a circuit failure. Internal circuits monitor:
- line voltage/line current
- correct functioning of the SSR
- SSR input status
The relay is designed for applications where immediate fault detection is required.
A red LED indicates an alarm, a green LED indicates DC control supply OK (half LED light intensity) resp. relay switched ON (full LED light intensity).
