G7J-2A2B-B DC24

Power relays are used to control the flow of electricity in a wide variety of industrial applications. The G7J-2A2B-B DC24 power relay is one such product from OMRON, a renowned maker of electro-mechanical components. In this article, we will discuss the application field and working principle of this particular product.

Application Field

The G7J-2A2B-B DC24 is a DC-rated, 2-pole, 5 A power relay with LED indicator and long-life construction. It is designed to be used in a wide variety of applications, including control panels, power supplies, lighting systems, pump motors, and industrial machinery. It is a cost-effective option for controlling low-voltage, DC-powered circuits.

Working Principle

The G7J-2A2B-B DC24 is a latching relay, meaning that it requires a momentary pulse of current to activate or deactivate the relay. To activate the relay, an electromagnet within the relay is energized, causing a contact to move to the closed position and remain there, even after the energizing current is removed. To deactivate the relay, a reverse pulse is sent through the coil, which causes the contact to move to the open position and stay there.

The LED indicator built into the relay allows for quick and easy viewing of the relay state. When the relay is activated, the LED will light up; when it is deactivated, the LED will be off. This assures the user that the relay is in the correct state for its intended purpose.

Conclusion

The G7J-2A2B-B DC24 is a reliable, cost-effective solution for controlling low-voltage, DC-powered circuits. Its two-pole, 5 A design and LED indicator make it well-suited for a variety of applications, including control panels, power supplies, lighting systems, pump motors, and industrial machinery. Its latching design ensures that it will remain in the desired state, providing peace of mind for the user.
