Product Description
Ordering Key
Solid State Relays
System Monitoring Relays (Sense Relay)
Type RA.... .....S
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
High surge current capability
Alarm output signal
LED indication for alarm and supply
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).
