A Solid State Relay (SSR) is an electronic switching device, which contains no moving parts. It is comprised of a trigger or sensing device, an electrical output, and a control circuit. Commonly used in industrial, commercial and residential applications, Solid State Relays are ideal for controlling motors, lights, thermocouples, solenoids, valves, pumps and fans. One such device suitable for these applications is the G3VM-201G2.

G3VM-201G2 Application Field

The G3VM-201G2 is an optically coupled SSR that is small-sized and low-priced, making it ideal for applications requiring low power consumption and simple control. It is predominantly utilized for low power switching and can be connected to all types of DC and AC loads. It can be used to control lighting and HVAC systems, pumps and fans, solenoids, valves, microwaves, and other industrial-grade circuitry and equipment. In addition, this SSR is well-suited for any medium-intensity electrical resistance load and is even compatible with general-purpose relays.

Working Principle

The central principle of the G3VM-201G2 SSR is to provide electrical isolation between the input and output devices to protect them from overcurrent and other factors. This SSR is not designed to be driven directly – it requires either an interface circuit or a PLC to control its operation through an input signal. When input power is applied, the triac lever is charged through the LED while the diode prevents the triac from passing any DC current. This produces an ohmic energy across the triac, allowing the electrical shield to be broken, creating a conducting path between the output terminals.

Performance

The G3VM-201G2 offers excellent performance. Its rated input voltage is 3-20 VDC for both normally open and normally closed SSRs. The maximum operating power is 5 W, providing a maximum switching power of 0.2 A/ 10 VDC. The operating temperature range is from -40°C to 85°C. In addition, the SSR has an insulation resistance of 100 MΩ at 500 VDC, making it suitable for a wide variety of applications.

Conclusion

The G3VM-201G2 is a reliable and cost-effective Solid State Relay, ideal for applications requiring low power consumption and simple control. This SSR is predominantly utilized for low power switching and can be used to control lighting and HVAC systems, pumps and fans, solenoids, valves, microwaves, and other industrial-grade circuitry and equipment. It offers excellent performance making it suitable for a wide variety of applications.
