COIL INTERNAL CIRCUIT
AC operating coil
DC 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, voltage drops to the coil of up to 50% of
the rated coil voltage for one second maximum.
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.
