Power relays, which are designed to conduct or switch on and off electrical currents of more than 2 Amps, are essential in many industrial settings. The HJ2-DC12V-6 is a power relay that is highly used and is known for its dependable performance. This power relay has multiple applications and its working principles depend entirely on the specific application. In this article, the applications and working principles of the HJ2-DC12V-6 power relay will be discussed.

Motor Control

The most common application of the HJ2-DC12V-6 power relay is in motor control. In this case, the power relay is used to enable the motor to be switched on or off through the application of an external voltage. The working principle is that when an external voltage is applied to the relay, it switches on and the motor is activated. Conversely, when the voltage is removed, the relay switches off and the motor is deactivated. It should be noted that unless the voltage is within the specific voltage requirements of the relay, it will not switch on or off and the motor will remain inactive.

Light Control

The HJ2-DC12V-6 power relay can also be used in light control applications. In this case, the power relay is used to enable a light to be switched on or off by the application of an external voltage. The working principle here is similar to that of motor control; when the relay switches on, the light is activated, and when it switches off, the light is deactivated. Again, unless the voltage is within the specific requirements of the relay, it will not activate.

Safety Shut-Off

The HJ2-DC12V-6 power relay is also used in safety shut-off applications. In these cases, the power relay is used to disconnect the power to a particular device or system if it detects a specific fault or condition. The relay will then remain in the off position until it is manually reset. The working principle here is that the power relay is triggered by some type of sensor or input—such as a current or temperature limit—that is set in advance. If the sensor detects the predetermined level, the relay will immediately switch off, disconnecting the power to the device or system.

Interlocking Control

Finally, the HJ2-DC12V-6 power relay is used in interlocking control applications. In this case, the power relay is used to interlock two or more actions in order to prevent unintended operation. For example, a power relay can be used to interlock a motor and a pump so that the motor will not start unless the pump is already active. The working principle here is that the power relay will disconnect the power to the motor unless it senses the output of the pump. The output of the pump must be within the voltage requirements of the relay in order for it to operate sufficiently.

In summary, the HJ2-DC12V-6 power relay is a highly versatile device that can be used in multiple applications. While the working principles of the relay depend on the specific application, the common theme is that the relay switches on and off based on the application of an external voltage. This makes the HJ2-DC12V-6 power relay an essential component in many industrial settings.
