Signal Relays, Up to 2 Amps: TQ4-L-24V Application Field and Working Principle

Signal relays are electrical devices that control the flow of power from one circuit to another. They are a type of switch that uses an electromechanical actuation (a current-controlled mechanical process) to complete or interrupt a conducting path. Signal relays are different from regular relays, because they can respond to signals from other electronic components with a lower supply voltage than the power capacity they need to switch. This makes them ideal for applications where a low-voltage power supply is available, such as in computer control systems, alarm systems, and other electronics.The TQ4-L-24V is a signal relay designed to switch up to 2 amps with a supply voltage of 12 to 24 volts. It has a relay coil for actuation, a NO (Normally Open) contact, and a NC (Normally Closed) contact. This relay can be used in many applications, including digital electronic monitoring and control systems, automated control systems, and process control systems. In addition, it is dust-proof and vibration-proof, making it suitable for use in dusty or harsh environments.The working principle of the TQ4-L-24V is relatively simple. When the DC voltage applied to the relay is equal to or greater than its rated voltage, the electromagnet within the relay is actuated, and the contacts are closed. This allows the current to flow from the NO to the NC contact, connecting the two circuits. When the DC voltage applied to the relay drops below its rated voltage, the electromagnet deactuates and the connection between the two circuits is broken.The TQ4-L-24V has a wide range of applications due to its reliability and versatility. It can be used in alarm systems to detect and control various types of events, such as door opening and closing, motion activation, smoke and fire detection, and so on. Additionally, it can be used in temperature and humidity control systems and process automation systems.In summary, the TQ4-L-24V is a versatile signal relay that can switch up to 2 amps with a voltage supply of 12 to 24 volts. It has an actuating relay coil, a NO contact, and a NC contact. This relay is dust-proof and vibration-proof, making it suitable for use in harsh environments. It can be used in a variety of applications, including alarm systems, temperature and humidity control systems, and process automation systems.
