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.

Ordering Information

To Order: Select the part number and add the desired coil voltage rating (e.g., G7J-3A1B-B-AC100/120).

Note: The G7J-B and G7J-T relays require a W-bracket for mounting. Order the bracket separately below. To order a relay and bracket packed

together, add “-W1” to the part number before the coil voltage suffix. For example, G7J-2A2B-B-W1-AC100/120. Consult Omron for available

versions.

■Coil Data

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C (73°F) with tolerances of +15%/-20% for AC rated cur-

rent and ±15% for DC coil resistance. Performance characteristic data are measured at a coil temperature of 23°C (73°F).

2. The values given for AC rated current apply at 50 Hz or 60 Hz.

■Characteristics

Note: 1. Data shown are of initial value.

2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.

3. The operate and release times were measured with the rated voltage imposed and with any contact bounce ignored at an ambient

temperature of 23°C.

The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric strength.

Precautions

■Handling

•To preserve 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,

SO2, H2S, or organic gas.

•Do not allow a voltage greater than the maximum allowable coil

voltage to be applied continuously.

•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.

■Installation

Although there are not specific limits on the installation site, it should

be as dry and dust-free as possible.

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 relay. If 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 only. The 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 only. In the case of

automatic soldering, some flux may stick to the test button and the

relay. As 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.

■Connection

Refer to the diagram below when connecting a wire to the screw ter-

minals on G7J.

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.

■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.

■Coil Internal Circuit

If a transistor drives the G7J, then check the leakage current and connect a bleeder resistor if necessary.

AC operating coil

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.

DC operating coil

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 supply, confirm 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.

E max.:Maximum ripple

E min.:Minimum ripple

E mean:Mean DC voltage value

When driving the coil with a transistor, check the leakage current and

connect a bleeder resistor if necessary.
