Signal Relays, Up to 2 Amps

Signal relays are used in a variety of industrial and technological applications, from automating processes to controlling complex operations. A signal relay is an electronic device that controls an electrical circuit by connecting or disconnecting the circuit when triggered by an external signal. It is a switch that allows electricity to flow or disconnects the power under the control of a signal.The TXD2-L-12V-3 is a low-power, latching-style signal relay designed for a variety of applications. It is a durable, compact, and robust relay, allowing maximum current up to 2 A. This type of signal relay is primarily used in low-current circuits and works on 12V DC power supply. Its latching-style mechanism eliminates the need for continuous electrical power, and saves energy.

Application Field

The TXD2-L-12V-3 signal relay is an ideal choice for a wide range of applications, including automotive and electronic system applications. It is especially suitable for applications in dimmers, heating control, automotive air conditioning, motor starters, electric tools, sensors, and medical equipment. In addition, it is often used in applications that require synchronization, such as video games, digital film, and other audio-visual gadgets.

Working Principle

The TXD2-L-12V-3 signal relay operates by closing or opening an electrical contact when triggered by an external device. The external device, such as a transistor, provides the necessary electrical current to energize the coil of the relay to close the contact. The contact may be a relay, an electromagnet, or a switch.When energized, the coil creates an electromagnetic field, which attracts a metal disc connected to the contact, allowing the current to pass through and complete the circuit. When the coil is de-energized, the metal disc moves back to its original position, and the contacts open, disconnecting the circuit. This latching-style mechanism allows the relay to remain in a fixed position until it is triggered again—hence, no electrical current is needed to keep the circuit open or closed.In short, the TXD2-L-12V-3 latching-style signal relay provides reliable service in low-current applications, offering high performance and low power consumption. It is the ideal choice for a range of applications, especially those that require synchronization and maximum current up to 2A.
