G3VM-21LR1(TR)

Solid State Relays (SSRs) are electronic switching components that are used in many control systems today. The SSRs are used to switch an electrical current on and off with the aid of an externally supplied input signal. The G3VM-21LR1(TR) is one such Solid State Relay developed by Omron Corporation.

This particular SSR is a single-phase, zero-cross type which is ideal for controlling a low-power AC load in applications like motor drive systems, air conditioners, and vending machines. It is also suitable for use in communication networks, digital consumer electronics, and in industrial control applications.

Application Field of G3VM-21LR1(TR)

The G3VM-21LR1(TR) is a single-phase, zero-cross type SSR and is suitable for controlling a low-power AC load. These SSRs feature a wide current range from 2A to 21A. They are especially suitable for use in various applications such as motor drive systems, air conditioners, vending machines, digital consumer electronics and industrial control systems. They can also be used in communication networks.

Working Principle of G3VM-21LR1(TR)

The working principle of G3VM-21LR1(TR) is based on the basic principle of AC-ON/OFF control, where the switch control signal is used to open or close the loop. The inputs of the SSR are the input signal from the controller, and the power/ground connection. The input signal can be either a 0-10V DC signal or a TTL compliant input signal.

The output of the SSR is controlled by the input signal. When the input signal is low, the output of the SSR is off, whereas when the input signal rises, the output of the SSR switches on. The output voltage across the load is proportional to the input signal. The current across the load is determined by the type of the SSR. The G3VM-21LR1(TR)has a current range of 2A to 21A. This current range can be increased when two or more G3VM-21LR1(TR) SSRs are connected in series.

The G3VM-21LR1(TR) also features a built-in Zero-Cross latch circuit that ensures that the output voltage is in phase with the input signal. The protective features of the SSR include a reverse-battery protection circuit, which prevents short-circuit damage to the device.

In conclusion, the G3VM-21LR1(TR) is a Solid State Relay that is suitable for use in controlling a low-power AC load in applications such as motor drive systems, air conditioners, and vending machines. It has a wide current range from 2A to 21A and features a built-in Zero-Cross latch circuit which ensures that the output voltage is in phase with the input signal. It is also equipped with protective features such as reverse-battery protection circuit which helps to prevent damage to the device.
