Product Description
The industrial, 1-phase relay
with antiparallel thyristor out-
put is the most widely used
SSR due to its multiple appli-
cation possibilities. This relay
has been designed to inter-
face low voltage AC or DC
control systems with high
voltage resistive, inductive
and capacitive loads. The
zero switching relay switches
ON when the sinusoidal

curve crosses zero and
switches OFF when the cur-
rent crosses zero. The built-
in varistor secures transient
protection for the heavy
industrial applications, and
the LED indicates the status
of the control input. The clip-
on cover is securing touch
safety to IP 20. Protected
output terminals can take
cables up to 16 mm
