General Purpose Relay
G7J
• Ideal for 3-phase motor control applications and resistive
and inductive loads.
• No contact chattering for momentary voltage drops up to
50% of rated voltage.
• Withstands more than 4 kV between contacts that are of
different polarity and between the coil and contacts.
• Flame-resistant materials (UL94V-0) used for all insulation.
• Push-to-test button on all models lets user check contact
operation.
• Class B coil insulation available.

reserve performance, do not drop or otherwise subject the G7J
relay to shock.
•
The case is not designated to be removed during normal handling
and operation. Doing so may affect performance.
•
Use the power relay in a dry environment free from excessive dust,
SO

Do not allow a voltage greater than the maximum allowable coil
voltage to be applied continuousl

Do not use the relay outside of specified voltages and currents.
•
Do not allow the ambient operation temperature to exceed the
specified limit.

■
Microloads
The G7J is used for switching power loads. Do not use the G7J for
switching minute loads, such as signals.
Allow suitable slack on leads when wiring, and do not subject the ter-
minals to excessive force. Tighten the screw terminals to a torque of
0.78 to 1.18 N-m.
■
Installation
Although there are not specific limits on the installation site, it should
be as dry and dust-free as possible.
■
Quick-connect Terminals
Do not impose excessive external force on the G7J in the horizontal
or vertical directions when inserting the G7J to the quick-connect ter-
minals or when removing the terminals from the G7J. Do not attempt
to insert or pull out more than one terminal at a time.
PCB terminal-equipped relays weigh approximately 140 g. Be sure
that the PCB is strong enough to support them. OMRON recom-
mends dual-side through-hole PCBs to reduce solder cracking from
heat stress.
Mount the G7J with its test button facing downwards. The relay may
malfunction due to shock if the test button faces upwards. Be careful
not to press the test button by mistake, because the contacts will
actuate (ON) if the test button is pressed.
If the normal mounting direction is not used, carbides or powder from
contact abrasion that results from load switching will accumulate
inside the rela
y
.
I
f the relay is used past its endurance in this state,
insulation failure between circuits of different polarity or relay burning
may occur.
Be sure to use the test button for test purposes onl
y
.
T
he test button
is used for relay circuit tests, such as a circuit continuity test. Do not
attempt to switch the load with the test button.
If a voltage is applied to the coil, the test button will retract in an ON
state (i.e., an excited state).
■
Soldering PCB Terminals
Be sure to solder the PCB terminals manually onl
y
.
I
n the case of
automatic soldering, some flux may stick to the test button and the
rela
y
.
A
s a result, the G7J may malfunction.
■
Cleaning PCB Terminals
PCB terminals have semi-sealed construction which prevents flux
from penetrating into the relay base housing due to capillary action.
This type of relay cannot be immersed for cleaning. Do not wash with
any water or detergent.

As a rule, either a DC battery or a DC power supply with a maximum
of 5% ripple must be used for the operating voltage for DC relays.
Before using a rectified AC suppl
y
,
c
onfirm that the ripple is not
greater than 5%. Ripple greater than this can lead to variations in the
operating and reset voltages. As excessive ripple can generate
pulses, the insertion of a smoothing capacitor is recommended as
shown below.
The G7J incorporates a bridge rectifier circuit in the AC coil versions
that prevents contact chatter or dropout during a voltage drop. This
circuit allows the relays to withstand, with no vibration or shock, volt-
age drops to the coil of up to 50% of the rated coil voltage for one
second maximum.

If a triac, such as an SSR, drives the G7J, the G7J may not release.
Use a Power MOS FET in this case.
