From the name of the relay, RJ2S-C-A120, we know it belongs to the power relays, and it needs sufficient current (over 2 amps) to drive its operation. It is designed professionally for low-voltage heating control of households and industrial applications.

A power relay, as its name implies, is made to switch high-power circuits. For example, it can be used to trigger a DC motor or Lamp when you press a button, for instance. Being controlled by low voltage, the power relay is widely used in various circuits and electrical systems.

RJ2S-C-A120 Application Field

Let’s take a closer look at the RJ2S-C-A120. Its application fields include 32A/30V small electric motor starters, air conditioning/warm air central heating switching, and low-voltage general control, etc. It is commonly used to control the power switch and switching frequency conversion of electrical apparatus in the electro-mechanical equipment. Also, it has been widely applied in rectifier circuits, LASER control, protective systems, and industrial machines with various switching systems.

RJ2S-C-A120 Working Principle

The working of RJ2S-C-A120 is quite simple. When the control signal of the low-voltage side is applied to the power terminal, the power circuit is connected and the electrical device is activated. On the opposite situation, when the control signal of the low-voltage side is cut off, the power circuit will be closed and the electrical device is turned off as well.

Working Principle of RJ2S-CA120

Working Principle of RJ2S-C-A120.

The RJ2S-C-A120 mainly transforms the low-voltage control signal into a high-power signal, and it provides a secure switching and control for the electro-mechanical equipment in both normal and unhealthy environments, making it more reliable and stable.

The RJ2S-C-A120 is able to provide an excellent control interface for the large power-control systems, and work better than the manual switch. This power relay is specially designed to handle high current in extreme environments, and can maximize protection. It is also considered to have an environment-friendly design, due to its low power consumption, low thermal radiation, and low noise.
