Product Description
This product is designed in
such a way as to replace elec-
tro-mechanical contactors,
especially when switching is
frequent. It has an integrated
heatsink and over-voltage pro-
tection.
The heatsink is
moved to the back for optimal
space saving in the panel and
easy wire mounting at the front
of the relay.
The relay with antiparallel
thyristor output is the most
widely used industrial SSR
due to its multiple application
possibilities and robust con-
struction. This relay can be
used for resistive and induc-
tive loads.
The zero switching relay
switches ON when the sinu-
soidal curve crosses zero and
switches OFF when the cur-
rent crosses zero. A green and
a red LED give status of the
control input and alarm
respectively.

Notes
1
Basic models with DC control input (without over-temperature protection or fan) have both U-type and E-type terminal connections
2
All models with over-temperature protection option (suffix "P") or AC control input are only available with type "E" terminals
3
Fan switching is internally controlled. Fan requires an external supply connected to the fan supply input(s)
4
With integrated fan and over-temperature protection - fan will automatically switch on when necessary
