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

- **•System (line and load) monitoring relay** 

- **•Zero switching** 

- **•Rated operational current: 25, 50, 90 and 110 AACrms** 

- **•Rated operational voltage: 120, 230, 400 and 480 VACrms** 

- **•High surge current capability** 

- **•Alarm output signal** 

- **•LED indication for alarm and supply** 

## **Product Descri tion p** 

The system monitoring solid The relay is designed for state relay (sense relay) proapplications where immediate vides an alarm output in the fault detection is required. event of a circuit failure. A red LED indicates an Internal circuits monitor: alarm, a green LED indicates - line voltage/line current DC control supply OK (half - correct functioning LED light intensity) resp. of the SSR relay switched ON (full LED - SSR input status light intensity).
