General Purpose Relay G7J 743 Coil Internal Circuit AC operating coil DC operating coil A2 A2 A1 A1 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, voltage drops to the coil of up to 50% of the rated coil voltage for one second maximum.

Precautions Handling Cleaning PCB Terminals * 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. 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. 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 recommends dual-side through-hole PCBs to reduce solder cracking from heat stress. Connection Refer to the diagram below when connecting a wire to the screw terminals on G7J. 7.6 (0.299) 8.8 (0.346) 7 (0.276) 4.5 (0.177) M3.5 Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Maximum tightening torque is 10 kgf-cm (0.72 ft-lbs). General Purpose Relay G7J 747 Terms and Conditions of Sale 1. Offer; Acceptance.
