Solid State Relays are the commonly used devices in electrical and electronic circuit for remotely controlling on and off alternating current loads. They are often used in industrial control, building automation, remote sensing and monitoring applications. G3VM-81G1(TR) is an example of such solid state relay. The G3VM-81G1(TR) is a solid-state relay (SSR) with a wide range of application fields.

The G3VM-81G1(TR) is a long life, low power, low cost, double-pole, double-throw (DPDT) relay for use in load control, signal switching, and circuit protection applications. It is designed to switch DC or AC loads up to 240Vac/0.5A, 60VDC/0.5A, and 50W or (Vac+2%) with a wide range of temperatures ( -55°C to +85°C). It has a high switching frequency of up to 2kHz and a wide-range voltage supply of 6 to 24Vdc.

The G3VM-81G1(TR) is designed with a built-in thermal fuse that prevents overloading of the output load. It also has an excellent thermal protection feature, which prevents unplanned power consumption due to thermal run-away. The relay does not include a built-in circuit breaker, so an external circuit breaker must be used to protect the relay and the loads connected to it. The rated load/resistive load of this SSR can be effectively switched off at any time.

The working principle of the G3VM-81G1(TR) is based on solid-state semiconductor technology. An input voltage (typically 12Vdc) is applied to the SSR control input and the controlled load is connected across the relay output terminals. When the input voltage is off, the relay will be in an off-state and no current will flow through the controlled device. When the input voltage is applied, the internal semiconductor switch will close, allowing the load to be supplied with voltage. The state of the SSR can be checked by a red LED indicator that will be on when the SSR is in an on-state and off when in an off-state.

The G3VM-81G1(TR) relay is suitable for a wide range of industrial and commercial applications such as lighting control, motor control, safety systems, HVAC control, and other signal switching applications. It is also commonly used in telecommunications, automotive, and medical equipment.

Overall, the G3VM-81G1(TR) is a versatile, reliable, low cost, long life, and low power solid state relay that can be used in various application fields. It has a wide range of features and provides reliable switching of up to 240Vac, 60VDC and 50W loads with excellent temperature protection. The protective thermal fuse ensures a longer life and increased safety. The SSR is also designed with a built-in red LED indicator to show on and off-state of the relay.
