Product De scrip tion
The industrial, 1-phase relay
with antiparallel thyristor output is the most widely used
SSR due to its multiple application possibilities. This relay
has been designed to interface 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 current 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 mm2.
