Product Description
Ordering Key
RN 1S 23 H 30 NO
The system monitoring
Solid State Relay (Sense
Relay) provides an alarm
output in the event of a cir-
cuit failure. Internal circuits
monitor:
- line voltage
- load current
- correct functioning of the SSR
- SSR input status
The relay is designed for
applications where immedi-
ate 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).
