Power Relays, Over 2 Amps: JC2A-DC12V-TV Application Field and Working Principle

The JC2A-DC12V-TV is a high-quality, low-cost, high-reliability, ultra-compact, miniaturized 2-pole (SPDT) TV relay for current rating up to 2 Amps. This type of relay is specifically designed for applications where power control is needed both in terms of on/off operations and proportional control.

Application Fields:

The JC2A-DC12V-TV relay is commonly used in a wide range of industrial, automotive and household control applications, such as general-purpose motors, heater controls, lighting switches, door locks, etc. It can also be used for control power measurements and pulse control for industrial automation.

Working Principles:

The JC2A-DC12V-TV relay consists of two components: a contactor and a switching system. The contactor is a coil of metal, usually copper or aluminum, that carries the current when the relay is energized and performs the switching function. The switching system controls the movement of a reed switch, by magnetic force. When the relay is energized, an electric current flows through the contactor, producing a magnetic field that attracts the reed switch. This causes the contacts to close, and the load is connected to the power supply.

The JC2A-DC12V-TV relay is also known as a latching relay. Unlike other types of relays, which are energized continuously, a latching relay holds its position even if the power is removed. It has two positions: on and off. When the relay is insulated, the switch is ‘on’. When it’s energized, the switch is ‘off’. The latching relay can be used to control a variety of devices, such as light fixtures, motors and pumps.

The JC2A-DC12V-TV relay is generally considered very safe for use, though there are precautions one needs to take when handling and connecting them. Relays must be installed according to the instructions and the terminals must be insulated for maximum safety. It is important to read all installation instructions before connecting the relay to the power circuit.
