The G3VM-401FR(TR05) is a solid state relay from Omron. It is a one-of-a-kind device that utilizes Insulated Gate Bipolar Transistor (IGBT) to efficiently control electrical loads directly from a photodiode or microcomputer. This SSR provides features such as plug-in connections, high reliability, and small form factor. It is widely used in switching applications, such as motors, lighting, welding, and heating.

Overview

This paper introduces the G3VM-401FR(TR05) Multi-Voltage SSR, which is an electrically isolated, phase-controlled thyristor module. This device is designed to control electrical loads with either a Photodiode or a microcomputer. The G3VM-401FR(TR05) operates at 12-48V AC/DC, and each channel has built-in reverse polarity and over-temperature (10°C~+50°C) protection. It also has a Latch to prevent accidental switching off, and AC/DC indicator lights.

Applications

The G3VM-401FR(TR05) device has numerous potential applications. It is well-suited to switching applications, such as motor control, lighting, welding, AC/DC load control, and heating. The G3VM-401FR(TR05) can also be used in telecommunications, industrial equipment, medical equipment, HVAC/R, and automotive industries, because of its high-performance switching capabilities.

Working Principle

The G3VM-401FR(TR05) is designed to control an electrical load directly from a photodiode or microcomputer. It works by controlling the flow of electrical current using a semiconductor material, which is placed between the main supply line and the load line. The SSR works by controlling the conductivity of the semiconductor material using the output current from the photodiode or microcomputer.

When the photo diode or microcomputer output current is low, the semiconductor material of the G3VM-401FR(TR05) switches to a non-conducting state. When the output current is higher, the material will conduct, allowing current to flow from the power line to the load. This action is called switching, and thus the device can be used to control electrical loads effectively.

Advantages of the G3VM-401FR(TR05)

Since this SSR uses a photodiode or microcomputer instead of a mechanical relay, it achieves high reliability and quick response time with low power consumption. It is also low cost, as it requires fewer components to assemble compared to other SSR designs. Finally, the G3VM-401FR(TR05) also features a device break-before-make operation, so it is suitable for use in applications where a load circuit break must occur before a new circuit is established.

Conclusion

The G3VM-401FR(TR05) is an advanced Solid State Relay (SSR) that utilizes a photodiode or microcomputer for switching loads. It provides users with exceptional features such as plug-in connections, high reliability, and small form factor. This SSR also has numerous applications, such as motor control, lighting, welding, and heating. Finally, the G3VM-401FR(TR05)’s unique design ensures an accurate, reliable, and energy-efficient operation even in harsh environments.
