Carlo Gavazzi Solid State Relay 1-Phase Zero-Cross Monitoring RA4825L12NCSS00

Carlo Gavazzi Solid State Relay 1-Phase Zero-Cross Sense System Monitoring, Control: 20-32VDC, Operational: 480VAC, 25A, Alarm: NPN NC, Option: S00.

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 ON (full LED light intensity).
