Solid State Relays (SSRs) play a vital role in industrial and commercial applications across a wide range of industrial sectors. G3VM-21LR(TR) is a highly reliable and cost-effective SSR, that offers superior performance and features for automation, heating, motor control, and many other applications. In this article, we will look at the application field and working principle of G3VM-21LR(TR).

Applications of G3VM-21LR(TR)

The G3VM-21LR(TR) is suitable for a wide range of applications, including:

• Industrial motor control
• Programmable logic controllers (PLCs)
• Heating and cooling systems
• Air-conditioning and refrigeration
• Lighting and lighting control
• Test and monitoring systems
• Industrial automation and process control

The G3VM-21LR(TR) is also capable of fast switching, making it ideal for applications that require rapid response times, such as in manufacturing, where rapid switching can reduce downtime and improve efficiency. The SSR can also handle higher loads than traditional mechanical relays, allowing it to be used in applications with high inrush current or high load duration, such as in high power motor starts.

Working Principle of G3VM-21LR(TR)

The G3VM-21LR(TR) utilizes an optically isolated semiconductor element, such as a thyristor, to control current. The semiconductor element is operated using an optical coupler which is optically connected to an external control source, such as a PLC, which when activated sends a signal to the semiconductor element closing its control contacts. The control contacts are connected to a load, such as a motor. When the external control source sends a signal to the SSR, it is triggered, activating the semiconductor element and turning on the power supplied to the load.

The G3VM-21LR(TR) is a contact self-holding SSR, which means that the SSR remains active even after the external control source is deactivated. This feature makes the SSR suitable for applications that require the load to remain powered for long periods of time, without the external control source being continuously activated. If the external control source is deactivated, the SSR will remain active until the power to the SSR is cut off.

The G3VM-21LR(TR) is rated for a maximum of 6 Amps, with a maximum working voltage of 250V AC / DC. It also has a wide operating temperature range, which allows it to be used in a variety of conditions and environments. The G3VM-21LR(TR) is also designed with surge protection, which ensures that it is protected from surges in the supply voltage, which could otherwise damage the SSR and the connected load.

Conclusion

The G3VM-21LR(TR) is a highly reliable and cost-effective Solid State Relay, which can be used for a wide range of applications. The SSR is capable of fast switching, and is rated for a maximum of 6 Amps, with a maximum working voltage of 250V AC/DC. It is also designed with surge protection, and has a wide operating temperature range, making it suitable for applications in a variety of conditions. In addition, it is a contact self-holding SSR, which means that the SSR remains active even after the external control source is deactivated.
