## **Solid State Relays System Monitoring Relays (Sense Relay) Type RA.... .....S** 

- System (line and load) monitoring relay 

- Zero switching 

- Rated operational current: 25, 50 and 110 AACrms 

- Rated operational voltage: 230, 400 and 480 VACrms 

- High surge current capability 

- Alarm output signal 

- LED indication for alarm and supply 

**Ordering Key RA 23 25 H 06 NO S** 

**Product Description** 

The system monitoring solid The relay is designed for Solid State Relay state relay (sense relay) proapplications where immediate Switching mode vides an alarm output in the fault detection is required. A Rated operational voltage event of a circuit failure. Inter- ~~0~~ red LED indicates an alarm, a Rated operational current nal circuits monitor: green LED indicates DC conControl input - line voltage/line current trol supply OK (half LED light - Blocking voltage correct functioning of the intensity) resp. relay switched Alarm output type SSR ON (full LED light intensity). 

Control input Blocking voltage Alarm output type Sense SSR 

- SSR input status

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
