J7KN-316 110 Application Field and Working Principle

Power relays, with a current rating over 2 amps, fall into the category of J7KN-316 110 relays. These relays are designed to control high-power electrical circuits and switch large currents on and off.

The J7KN-316 110 relay is designed for applications where the high current needs to be controlled and regulated. It is typically used in power supplies, motor drives, industrial machines, lighting control, and automation systems.

A typical J7KN-316 110 relay is composed of a magnetically activated armature, a set of contacts, and a holding circuit. The armature is a steel rod that is attached to the rear of the relay and is responsible for the motion of the relay. It is activated by a magnetic field created by the coil inside the relay which is energized when an electrical current is applied to it.

The contacts are the electrical connection points of the relay and are responsible for completing the circuit. When the armature is activated, the contacts are opened or closed, depending on the switch setting. The contacts are protected from voltage spikes and arcing by the vacuum inside the relay.

The holding circuit is responsible for energizing the armature and the contacts when the current is applied to the relay. The circuit is made out of four components: the coil, a diode, a resistor, and a capacitor. When a current is applied to the coil, it creates a magnetic field which activates the armature and opens or closes the switch. The diode and resistor ensure that the current is only applied to the coil when the switch is open, and the capacitor is used to store and release energy when the switch is open and closed.

The J7KN-316 110 relay is an important component in power control applications and is a necessary component for switching large currents on and off. It is reliable, easy to use, and is designed to handle high current applications.
