Signal Relays, Up to 2 Amps - D3422 Application Field and Working Principle

Signal relays, also known as low-voltage contactors, are electromechanical switches mainly used for low-current applications such as signal transmission and conversion in electronic circuits. The D3422 is a type of signal relay that handles up to 2 Amps, making it suitable for a wide range of applications.The D3422 is a DPDT (double-pole double-throw) contactor and has a maximum switching current of 2 Amps. It features two mechanically and electrically separate contacts and is suitable for AC or DC operation. The D3422 is mainly used in a variety of industrial, commercial, residential, and signal control applications. It is ideal for use in general purpose motor control, temperature control, signal switch, lighting, and relay protection applications.The D3422 operates based on an electric solenoid that is actuated by an electrical control signal. The electric solenoid consists of a solenoid coil and an armature. When a current is passed through the solenoid coil, the armature is attracted and moves towards it, resulting in the armature arm being held in a fixed position. The armature is a link between the control signal and the contact point, allowing the connection to open or close when the control signal is activated.The construction of the D3422 is lightweight and allows for simple installation. It features a color-coded actuator which can be easily identified for troubleshooting. It is also equipped with a removable dust cover that prevents dust and other contaminants from getting into the contact points.The D3422 is also a durable device. It has a contact pressure of 4.5 to 8.5 Newtons, which ensures that the contacts remain tightly closed and remain in contact even under extreme temperatures and vibration. It also uses a high-quality dielectric material to ensure that the contacts are insulated and not affected by vibration or dirt.In summary, the D3422 Signal Relay is a versatile and reliable signal relay designed for low-current applications. It is ideal for industrial, commercial, residential, and signal control applications, and features a removable dust cover, a color-coded actuator, and a durable contact pressure. With its high-quality construction, the D3422 provides an excellent performance and a long service life.
