Power Relay
A High-capacity,
High-dielectric-strength Relay
Compatible with Momentary
Voltage Drops
• No contact chattering for momentary voltage drops up to 50% of
rated voltage.
• Wide-range AC-activated coil that handles 100 to 120 or 200 to
240 VAC at either 50 or 60 Hz.
• Miniature size for maximum switching power, particularly for
inductive loads.
• Flame-resistance materials (UL94V-0-qualifying) used for all
insulation material.
• Quick-connect, screw, and PCB terminals, and DIN track
mounting available.
• Conforms to UL, CSA, TUV and meets IEC950.
• Safety design with contact gap of 3 mm.

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.

■Precautions
● Please refer to “PCB Relays Common Precautions” for general precautions.
Correct Use
● 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
G
accidentally. Doing so may turn ON
7
the contact.
L
• 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.
• Do not wash down the entire Relay
because it does not have an airtight
construction.
● Connecting
• Refer to the following table when
connecting a wire with a crimpstyle
terminal to the G7L.

to 120 VAC are values measured on
the basis of 100 VAC.

• 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.

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
● 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.
