Product Description
The industrial, 1-phase relay
with antiparallel thyristor
output is the most widely
used industrial SSR due
to its multiple application
possibilities.
The
relay
can be used for resistive,
inductive and capacitive
loads. The zero switching
relay switches ON when the
sinusoidal curve crosses zero
and switches OFF when the
current crosses zero.
The instant-on relay with DC
control input can be used
for phase control. 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 protection to IP 20.
Protected output terminals
can handle cables up to
16mm

Notes:
- Control input lines must be installed together to maintain products’ susceptibility to Radio Frequency interference.
- Performance Criteria 1: No degradation of performance or loss of function is allowed when the product is operated as intended.
- Performance Criteria 2: During the test, degradation of performance or partial loss of function is allowed. However, when the test is complete the product
should return operating as intended by itself.
- Performance Criteria 3: Temporary loss of function is allowed, provided the function can be restored by manual operation of the controls.
