furnaces
• Control application with
high switching speed
PROFILE
Zero crossing relay with antiparallel
thyristor output is the most used solid
state relay in industrial applications.
In fact, it can be used for resistive,
inductive and capacity loads.
"Zero crossing" relay is energised when
voltage meets the zero point and
disenergised when current meets the
zero point, depending on the signal
control on the input circuit.
This relay has been designed to stand
high-value transitory applications .
When the relay has to stand high
currents for a long period, it is necessary
to grant a proper dissipation and an
adequate electrical connection between
relay terminals and the load.
Varistors, fuses, thermostats and fans
are available as fittings.
Use the relay with an opportune heatsink
(see section accessories).
