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 90 AACrms • Rated operational voltage: 120, 230 and 400 VACrms • High surge current capability • Alarm output signal • LED indication for alarm and supply Product 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 Ordering Key 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).
