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

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.
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.

When driving the coil with a transistor, check the leakage current and
connect a bleeder resistor if necessary.
