Solid State Relays System Monitoring Relays (Sense Relay) Type RA.... .....S
Series Description:The system monitoring solid state relay (sense relay) provides 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
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
