Product Description

Ordering Key

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

Safety

When using a semiconductor contactor, the
electric configuration is split into a safety part
and a control part. In the safety part the isolation
of the load from the mains is assured by insert-
ing switchgear that provides galvanic isolation
from the power supply. A contactor or isolator
can be mounted in series with the Solid State
Relay to achieve this isolation. The contactor
can be a very economical type as the switching
is done by the Solid State Relay.
