The system monitoring solid state relay (sense relay) pro- vides 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).
