The G3VM-351D(TR) is a type of Solid State Relay (SSR), a device which allows electric current to flow from a connected power source to a certain load. SSRs are used in a variety of industrial and consumer applications, acting as an electrical switch to turn devices on and off, control machines or circuits, and execute other tasks. G3VM-351D(TR) is a photo-triac type SSR, with high input-output isolation voltage, a broad range of operating temperatures, low energy consumption, and a long service life.

The G3VM-351D(TR) consists of a photocoupler, a control circuit, a triac, and terminal block. The photocoupler utilizes a light source to control the conduction of the triac, allowing electric current to flow from the input side to the output side. When a voltage is applied to the input side of the SSR, the photocoupler will be illuminated and create a current, which in turn will trigger the control circuit. The control circuit sends current to the triac gate, allowing the current to flow from the input side to the output side of the SSR.

The G3VM-351D(TR) allows for zero-cross conduction, which further reduces the power loss and improves the circuit response time. It is also capable of suppressing voltage peaks generated by the triac switching, and has a built-in zero-cross circuit which send a signal when the input voltage reaches a specific point. The G3VM-351D(TR) is also available with a built-in control amplifier and a single-step drive control.

The G3VM-351D(TR) is designed for both low- and high-power applications. The maximum rated operation voltage is 30VAC or 32VDC, and the control response frequency range is from 0-80 Hz. The SSR can switch up to 5A/260VAC, and the input control voltage range is from 9V to 30V, with a terminal resistance of 100KΩ. The breakdown voltage is 40V, and the surge-withstanding voltage is 500V.

As a Solid State Relay, the G3VM-351D(TR) is commonly used in automative equipment, industrial machinery, consumer electronics, office automation systems, and medical device applications. Its robust design, high input-output isolation voltage, and long service life make it ideal for use in high-power applications. It is also a cost-effective solution, as compared to traditional electromechanical relays.
