Power Relays, Over 2 Amps: G7J-4A-B DC100 Application Field and Working Principle

The G7J-4A-B DC100 is a power relay in the category of power relays above 2 amps. In general, power relays are primarily used for switching, isolating, and protecting circuits in a wide variety of industries and applications. It is the size, isolation, and switching capacity that determines the type of application and power relay to select for the application or system. Being a power relay this size, the G7J-4A-B DC100 is suitable in a number of different applications.

The G7J-4A-B DC100 is a low current rated, 10 amp device with a coil voltage of 12 volts DC. This device can carry a maximum current of 10 amps when the atomized contacts are closed. This power relay has a number of features that makes it suitable for a variety of applications.

One of the primary features of the G7J-4A-B DC100 is its ability to be activated by external devices. This includes a rotary switch, safety circuit, or an electronic switch. The power relay can be used in these applications due to its ability to accept external inputs to switch the power on/off. Additionally, the G7J-4A-B DC100 can provide a number of protections that are specifically designed for high power applications including over temperature protection, under voltage protection, under current protection, and over current protection.

The G7J-4A-B DC100 can also be used in systems for motor control, lighting, and remote control. This is because the device is capable of switching, starting, and stopping motors as well as providing switching and status indications from the relay to an external monitoring device. The power relay can also provide signals to light circuits when the external device is activated.

The G7J-4A-B DC100 operates on the principle of electromagnetic induction. This occurs when an electric current flows through a wire and encounters a magnetic field. The movement of the electric current creates a magnetic field, and when the magnetic field is changed due to an external force, an electric current is created in the wire. The G7J-4A-B DC100 uses this principle in tandem with a rotary switch or safety circuit to actuate the relay. When the external device changes the magnetic field, the relay coil is energized and the power relay is activated.

The G7J-4A-B DC100 is a versatile power relay designed to operate in a variety of applications and systems. This device can handle up to 10 amps when the contacts are closed, while providing reliable protection and switching for different applications. The device is suitable for motor control, lighting, and remote control systems due to its ability to provide status and switching indications. It operates on the principle of electromagnetic induction, making it suitable for use with external devices and circuits to activate the relay.
