Solid State Relays (SSR) refer to electronic switches that are used to engage AC loads with low-level control signals. They are used in many fields such as telecommunications and home appliances. They are preferred over its mechanical counterparts due to their noise immunity, long life and greater reliability. The G3MB-202PL-DC24 is one such SSR. In this article, we shall discuss the application field and working principle of this device.

Application field

The G3MB-202PL-DC24 is a lightweight, compact module that is used to control low-power AC loads (resistive and inductive). It is suitable for powering LED lighting, general-purpose AC motors, Pumps, solenoid etc. This SSR is highly reliable and safe to use with no spark hazard as well as low interference. Furthermore, it offers complete insulation between input and output so as to prevent any short circuit and other electrical damages. This makes it an ideal choice for many demanding engineering applications such as heating/cooling equipments, home appliances etc.

Working principle of G3MB-202PL-DC24

The G3MB-202PL-DC24 SSR consists of a main PCB and two opto-isolators. The low-current control signal is fed to the input of an opto-coupler. The LED inside it emits light and this light is received by a photodetector inside the other opto-isolator. This causes the output transistor to turn ON and the AC load is engaged. Furthermore, the device also contains a zero-cross circuit which allows it to turn the AC load ON only after the zero-crossing point of the AC waveform. This ensures that no unwanted noise is generated.

The G3MB-202PL-DC24 is an ideal choice for low-power AC loads due to its long life, high reliability, safety, and low interference levels. It can be used in a variety of applications such as pumping systems, home appliances, heating/cooling equipments etc. It works on the simple opto-isolator principle which makes it highly efficient and allows it to be used in a variety of hazardous environments.
