■Coil Internal Circuit

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.

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.

■Approvals

UL 508 and 1950 (Recognized, File No. E41643)/CSA 22.2 No. 14 (Certified, File No. LR 35535)

Note: 1. The rated values approved by each of the safety standards may be different from the performance characteristics individually defined in

this catalog.

2. In the interest of product improvement, specifications are subject to change without notice.

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.

■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.

■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.

■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. Maximum tightening torque is 10 kgf-cm

(0.72 ft-lbs).
