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).

Solid State Relay Dissipated Power
Calculation
Single phase state relay
PdGQ .. 15/25 = 1,45 . Irms [W]
PdGQ .. 50/90 = 1,35 . Irms [W]
IRMS = single-phase load current
Heatsink Thermal Resistance
Calculation
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 over-
heating by using a heatsink (accessory).
The heatsink must be sized according to
room temperature and load current (see
technical data).

spread 1 gram of thermoconductive sili-
cone paste (we recommend DOW COR-
NING 340) on the dissipative metal surfa-
ces of the module.
The surfaces must be clean and the ther-
moconductive paste must not contain
any impurities. As alternative it is also
possible to use the slide SIL-GQ availa-
ble as accessory.
Alternately tighten the two fastening
screws until reaching a torque of
0.4…0.6 Nm.
Wait 5 minutes for any excess paste to
run off.
Alternately tighten the two fastening
screws until reaching a torque of
1.2…1.4 Nm.
Attention
The contact surface of the heatsink
module may have a maximum planarity
error of 0.1 mm and maximum roughness
of 0.02 mm.
The fastening holes on the heatsink must
be threaded and countersunk.
The heatsink must be grounded.

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 (inflamma-
ble 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”!
(use the holes in the cover for eventual re-calibration).
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.
• evitare la polvere, l’ umidità, i gas corrosivi, le fonti di calore.
• keep away from dust, humidity, corrosive gases and heat sources.
• The connection cable must be shorter than 3 meters if the current transformer is used.
Maintenance: Check the correct operation of the cooling fans at regular intervals; clean the ventilation air filters of the installa-
tion at regular intervals.
• Repairs must be performed only by specialized or appropriately trained personnel. Cut off power to the device before acces-
sing 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.
Technical service : GEFRAN has a technical service department. Defects caused by use not conforming to the instructions are
excluded from the warranty.
