Solid State Relays (SSRs) are an important type of device in an industrial automation or control application. The G3MC-202PL-VD-1 DC12 is a type of SSR that is used for a variety of applications. This article will discuss the application field of the G3MC-202PL-VD-1 DC12 and its working principle.

Application Field

The G3MC-202PL-VD-1 DC12 is a low-voltage AC output SSR that is used for low-power AC input control signals. It can be used to switch AC current in the range 0-4A. It is most commonly used to switch AC circuits in heating, cooling or illumination systems in residential, commercial and industrial applications. It is suitable for applications such as fan motors, appliances, and air conditioners.

The G3MC-202PL-VD-1 DC12 is also well-suited for applications that require low-level switching. It can be used to switch capacitive and inductive loads. It can also be used to switch low to high-power LEDs. It has a wide range of input voltages and provides a temperature range of -25 to +70°C.

Working Principle

The G3MC-202PL-VD-1 DC12 is a three-terminal solid state relay (SSR) that consists of a silicon controlled rectifier (SCR), photoelectric coupler, and baseboard. The SCR is a three-terminal solid state device that functions as an unidirectional current control element. The photoelectric coupler consists of a light-emitting diode (LED) and a photo transistor. The baseboard provides the necessary interface electrical circuitry.

The operation of the G3MC-202PL-VD-1 DC12 begins when an AC input voltage is applied to the input terminals. The input voltage then triggers the LED in the photoelectric coupler, resulting in the emission of light. The photo transistor then receives this light and conducts current. This current is then amplified and sent to the SCR, which controls the flow of the current. The SCR then switches the output current on and off based on the signal received.

The G3MC-202PL-VD-1 DC12 is an excellent choice for applications requiring low-level switching. It offers a simple, reliable solution for controlling AC power and is an economical way to switch low to high-power devices. It is easy to install and use and can provide years of reliable service.
