Solid state relays (SSRs) are reliable electrical devices that are composed of a switch, an LED light, and a metal oxide semiconductor field-effect transistor (MOSFET). SSRs are utilized in a wide range of applications, from controlling high voltage power distribution to regulating temperature and humidity. The G3VM-61B is a hybrid solid state relay from Omron Electronics which is ideal for applications in telecommunications, automotive, HVAC, and industrial automation. This article discusses their application fields and working principles.

Application Fields of G3VM-61B

The G3VM-61B is a single-phase or 3-phase solid state relay with a built-in fly wheel diode. It can be used in various applications such as motor control, lighting dimming, machine tool control, motor speed control, and industrial automation. Its unique features make it suitable for controlling high voltage supplies. The G3VM-61B is constructed of high-frequency relay switching with a built-in varistor which efficiently brings power up to 4,000VAC with an accessory. The unit is also protected against false triggering due to shock, vibration or EMI.

The G3VM-61B is also suitable for lighting control in HVAC systems and has an advantage over traditional relays because it consumes less power, reduces system size and minimizes the need for plugs. It is also suitable for industrial automation systems as it has excellent surge protection capabilities. In addition, the G3VM-61B is designed to be used in motor control applications due to its built-in fly wheel diode.

Working Principle of G3VM-61B

The G3VM-61B is a hybrid SSR which is composed of a controllable switch, an LED light, and a MOSFET. The SSR is made up of two terminals, one is an input terminal and the other is an output terminal. The input terminal is connected to a power source while the output terminal is connected to a load. When the power source is turned on, the input voltage is applied to the SSR’s MOSFET which is then triggered, resulting in a current flow from the power source to the load. The LED light indicates the status of the switch. When the switch is switched on, the LED will light up.

The G3VM-61B is designed for operation with a wide variety of input voltages, ranging from 24 to 380VAC. It supports a control voltage ranging from 4-24VDC and its switching current is up to 15A. The built-in varistor provides reliable surge protection against false triggering due to shock or EMI. Furthermore, the fly wheel diode helps reduce motor induced electrical noise.
