The industrial, 1-phase relay
with antiparallel thyristor out-
put is the most widely used
industrial SSR due to its mul-
tiple application possibilities.
The relay can be used for
resistive,
capacitive loads. The zero
switching relay switches ON
when the sinusoidal curve
crosses zero and switches
OFF when the current cross-
es zero. The instant-on relay

with DC control input can be
used for phase control. The
built-in varistor secures tran-
sient protection for the heavy
industrial applications, and
the LED indicates the status
of the control input. The clip-
on cover is securing touch
protection to IP 20. Protect-
ed output terminals can han-
dle cables up to 16mm
