System Monitoring Relays (Sense Relay)
Type RA.... .....S
鈥?System (line and load) monitoring relay
鈥?Zero switching
鈥?Rated operational current: 25, 50 and 90 AACrms
鈥?Rated operational voltage: 120, 230 and 400 VACrms
鈥?High surge current capability
鈥?Alarm output signal
鈥?LED indication for alarm and supply
Product Description
The system monitoring solid
state relay (sense relay) pro-
vides an alarm output in the
event of a circuit failure. Inter-
nal circuits monitor:
- line voltage/line current
- correct functioning of the SSR
- SSR input status
The relay is designed for appli-
cations where immediate fault
detection is required.
A red LED indicates an alarm,
a green LED indicates DC con-
trol supply OK (half LED light
intensity) resp. relay switched
ON (full LED light intensity).
