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).

fuse protections.

Rth = (90°C - T.amb. max) / Pd
where Pd = dissipated power
Max. amb. T = max air temperature inside
the electrical cabinet.
Use a heatsink with thermal resistance
inferior to the calculated one (Rth).
Installation notes
The device must be protected by a high
speed fuse (accessory).
Applications with power solid state relays
must also have a switch to isolate the
power line.
Protect the solid state relay against overheating by using a heatsink (accessory).
The heatsink must be sized according to
room temperature and load current (see
technical data).
Heatsink installation procedure:
spread 1 gram of thermoconductive silicone paste (we recommend DOW CORNING
340) on the dissipative metal surfaces of
the module.
The surfaces must be clean and the thermoconductive paste must not contain any
impurities. As alternative it is also possible to use the slide SIL-GQ available as
accessory.

•WARNINGS
WARNING: this symbol indicates danger.
Before installation, please read the following advices:
• follow the indications of the manual scrupulously when making the connections to the instrument.
• use a cable that is suitable for the ratings of voltage and current indicated in the technical specifications.
• if the instrument is used in applications where there is risk of injury to persons and damage to machines or materials, it is essential that it is used
with an auxiliary alarm device.
• It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment.
• The instrument must NOT be used in environments where there could be the presence of dangerous atmospheres (inflammable or explosive)
• During continuous operation, the heatsink may reach 100°C and remain at a high temperature due to thermal inertia even after the device is
switched off. Therefore, DO NOT touch the heat sink or the electrical wires.
• do not operate on the power circuit untless the main supply is disconnected.
• DO NOT open the cover if device is “ON”!
Installation:
• connect the device to the ground using the proper ground terminal;
• the power supply wiring must be kept separate from that of inputs and outputs of the instrument; always check that the supply voltage corresponds
to that indicated on the instrument cover;
• keep away from dust, humidity, corrosive gases and heat sources;
• is recommended in the electrical panel containing the GQ, install a fan near the group of GQ that keep air in movement.
Maintenance
• Check the correct operation of the cooling fans at regular intervals; clean the ventilation air filters of the installation at regular intervals
• Repairs must be performed only by specialized or appropriately trained personnel. Cut off power to the device before accessing internal parts.
• Do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.).
Using such solvents will compromise the mechanical reliability of the device. To clean external plastic parts, use a clean cloth wet with ethyl
alcohol or water
