Signal relays play a pivotal role in many different types of circuits. As an integral part of the electrical system, signal relays provide an efficient and cost-effective way of controlling and regulating power through a circuit. The TQ2H-L2-9V is one such signal relay that offers up to 2 Amps current capacity for a range of different applications. This article will explore the application field and working principle of the TQ2H-L2-9V.

Overview of the TQ2H-L2-9V

The TQ2H-L2-9V is a signal relay, designed for use with applications requiring up to 2 Amps current capacity. This device is perfect for a variety of systems that need to switch power on or off in response to an input signal such as a voltage or current. This signal relay is designed for either general purpose or convenience equipment.

The TQ2H-L2-9V has a low contact rating of 1 Amp DC and 2 Amps resistive AC. It is designed to respond to an input signal in the range between 10 and 16 Volts DC and is capable of switching on up to 16 Volts AC at 60Hz. This device is approved by a number of different safety agencies, including UL, CSA, EN, VDE, and TÜV.

Application Field and Working Principle of the TQ2H-L2-9V

The versatile TQ2H-L2-9V can be used in many different applications, such as site access control systems, remote alarm systems, household appliances, and industrial machinery. It is often used to provide reliable switching capabilities for devices such as remote systems, pumps, elevators, compressors, fire alarms, HVAC units, motors, and other high-power equipment.

The TQ2H-L2-9V operates on the principle of magnetically-augmented switching. This is accomplished by a solenoid coil mounted inside the relay body. When an input signal is applied to the coil, the magnetic field generated by the coil attracts a metal plunger, which then completes the contact between the relay\'s two terminals. The switched output is effectively completed when the plunger is actuated, and the circuit is opened when the plunger is released.

This mode of switching operation provides the TQ2H-L2-9V signal relay with a number of features that make it suitable for a wide range of applications. It is designed for reliable switching of up to 2 Amps current capacity, and it does not require mechanical contact between the relay and the signal source (input). Furthermore, it is capable of resisting electrical noise and withstands high in-rush current.
