Output LED
Output status is normally closed
without failure on the relay and
the load. The output LED is
normally ON.
In case of failure on the load
(open) or on the SSR (short-
circuit condition):
- the status is open
- the output LED is switched OFF
Important: If you use a long
wiring cable between the SSR
and the load (>25 meters), the
diagnostic system might not be
able to detect an open load.

The yellow LED luminosity
depends on:
– Load voltage.
– Control: ON or OFF.
– Load type.
The status outputs can be
connected in series.
NPN or PNP output is possible
with status.
Mains voltage lower than
specifications (150 Vac). The
SSR works correctly, but an
alarm status can be given
without control.
