Signal relays are electronic devices which are typically used to control a higher power circuit by a low power signal. This allows a small electric current or digital signal to control a larger electric current or other electronic systems. The TQ4-L2-4.5V signal relay is a 4.5V device with up to 2 Amps of current. This device is ideal for applications in which a low-current control signal must activate higher current driven outputs.

Overview of the TQ4-L2-4.5V Signal Relay

The TQ4-L2-4.5V signal relay is a 4.5V device with up to 2 Amps of current. This device is capable of switching up to 1000VAC/DC and has a built-in over current protection feature. It features compact dimensions and is suitable for surface mounting. The contact arrangement is a single pole single throw (SPST) with a normally open contact. This device is available in a range of coil voltages, including 4V, 6V, 9V, 12V, and 24V.

Application Field of the TQ4-L2-4.5V Signal Relay

The TQ4-L2-4.5V signal relay is ideally suited for applications which require a low-control signal to activate outputs with higher current. It is particularly suitable for general purpose switching, motor controllers, and lighting control. It is also well-suited for applications which require precise timing and control of complex electronic processes, as well as applications which require reliable detection of high or low voltages.

Working Principle of the TQ4-L2-4.5V Signal Relay

In its simplest form, the TQ4-L2-4.5V signal relay is designed to respond to an electrical signal by activating or deactivating a pair of contact terminals. When the coil of the signal relay is energized, a magnetic field is created around the coil which attracts an armature which is linked to the contacts. This movement of the armature causes the contacts to move from their normally open position to their closed position, completing the circuit. When the energized coil is then de-energized, the armature moves back into its original position, returning the contacts to their normally open position, thus breaking the circuit.

Conclusion

The TQ4-L2-4.5V signal relay is an electronic device that is used to control the current in a higher circuit by a lower signal. It can switch up to 1000VAC/DC and is suitable for surface mounting applications. It is well-suited for applications that require precise control of complex electronic processes, accurate detection of high or low voltages, reliable switching, and repeatability. Additionally, the TQ4-L2-4.5V signal relay has an over current protection feature.
