■Ratings
Coil
Note 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of
+15%/-20% for AC rated current and ±15% for DC coil resistance.
2. The inductances shown above are reference values.
3. Performance characteristic data are measured at a coil temperature of 23°C.
4. The maximum allowable coil voltage refers to the maximum value in a varying range of operating power
voltage, measured at ambient temperature 23°C.
5. The "to" (for example "100 to 120") represents the range of rated voltages.
Contacts
Note. When using B-series (screw) products, since the screw diameter of the contact terminal is M4, be careful
that the contact current should be 20 A or less according to JET standard (electrical appliance and material
control law of Japan).

G7L Power Relay
● Installation
• Although there are not specific limits
on the installation site, it should be as
dry and dust-free as possible.
• Using in an atmosphere of high
temperature, high humidity and
corrosive gas may deteriorate its
performance characteristic caused by
condensation or corrosive products,
resulting in failure or burn damage of
the Relay.
• PCB Terminal-equipped Relays weigh
approximately 100 g.
Be sure that the PCB is strong enough
to support them. We recommend
dual-side through-hole PCBs to
reduce solder cracking from heat
stress.
• Relays with test buttons must be
mounted facing down.
Be careful not to touch the test button
accidentally. Doing so may turn ON
the contact.
• Be sure to use the test button for test
purposes only (with test-button
models). The test button is used for
Relay circuit tests, such as circuit
continuity tests. Do not attempt to
switch the load with the test button.
● Micro Loads
• The G7L is used for switching power
loads, such as motor, transformer,
solenoid, lamp, and heater loads. Do
not use the G7L for switching micro
loads, such as signals.
● Soldering PCB Terminals
• Do not perform automatic soldering
but solder manually.
• Solder with the following conditions:
Soldering iron temperature (max.)
380°C, Soldering time within 10
seconds.
• Do not wash down the entire Relay
because it does not have an airtight
construction.
Correct Use
● Connecting
• Refer to the following table when
connecting a wire with a crimpstyle
terminal to the G7L.
• Allow suitable slack on leads when
wiring, and do not apply excessive
force to the terminals.
• Tightening torque
Coil: 0.78 to 1.18 N

When connecting with screws, if the
screws are not sufficiently tightened,
the lead wire can become detached
and may lead to abnormal heating or
fire caused by faulty contact.
• Mounting Torque
0.98N
.
m
Tighten with two M4 screws when
mounting.
(Top bracket type)
• Do not apply excessive force when
mounting or dismounting the Faston
receptacle.Insert and remove
terminals carefully one at a time. Do
not insert terminals at an angle, or
insert/remove multiple terminals at the
same time.
• Do not connect to the terminals by
soldering
• Refer to the following table for
recommendations of connectors
made by OMRON.
Note. The current should be 25 A when using receptacle terminals.

● Reference Data
• The ratio of rated voltage between 100
to 120 VAC are values measured on
the basis of 100 VAC.
● Operating Coil
(Coil internal connections diagram)
• DC Coil
• AC Coil
• If a transistor drives the G7L check the
leakage current, and connect a
bleeder resistor if necessary.
• The AC coil is provided with a built-in
full-wave rectifier. If a triac, such as an
SSR, drives the G7L, the G7L may not
release. Be sure to perform a trial
operation with the G7L and the triac
before applying them to actual use.
01
01
● DIN Track Mounting Adapter and
Front-connecting Socket
(DIN Track Mounting)
• The DIN Track Mounting Adapter and
Front-connecting Socket can be
mounted on the G7L with just one
hand and dismounted with ease by
using a screwdriver.
• To support the G7L mounted on a DIN
Track Mounting Adapter or
Front-connecting Socket, use the
PFP-M End Plate. Put the End Plate
onto the DIN Track Mounting Adapter
or Front-connecting Socket so that the
surface mark of the End Plate faces
upwards. Then tighten the screw of the
End Plate securely with a screwdriver.
(Screw Mounting)
• Screw-mount the DIN Track Mounting
Adapter or Front-connecting Socket
securely after opening screw mounting
holes on them.
• When cutting or opening holes on the
panel after the Front-connecting
Socket is mounted, take proper
measures so that the cutting chips will
not fall onto the Relay terminals. When
cutting or opening holes on the upper
part of the panel, mask the
Front-connecting Socket properly with
a cover.
■Precautions
● Please refer to “PCB Relays Common Precautions” for general precautions.
