The G2R-1-T AC12 is a power relay built by Omron. It is one of their larger power relays with a rated carry current of over 2 amperes. This is a single-phase relay with a number of features that make it very useful in applications requiring higher currents. In this article, we will discuss the application fields and working principles of the G2R-1-T AC12.

Applications

The G2R-1-T AC12 power relay can be used in a wide variety of applications. It can be used in the motor control field, for controlling the motor\'s start up and shut down. It can also be used for applications in power conditioning and distribution, such as power factor correction and power protection systems. The relay can also be used for air conditioning and refrigeration systems, and in the switchboard and SCADA systems.

In addition, the G2R-1-T AC12 power relay can be used in the lighting field, as it can be used to control the output of lights, allowing for dimming or flashing functions. It can also be used in HVAC systems, where it can be used for switching control of air conditioners. Finally, it can also be used in the emergency power supply systems, for controlling the inputs and outputs for reliable power in emergency situations.

Working Principle

The G2R-1-T AC12 power relay is a single-phase relay. It consists of a coil and an armature. When the electric current passes through the coil, the armature is attracted and pulls onto a set of contact points. This closes the circuit and allows the current to flow, thus completing the switch.

The G2R-1-T AC12 has a number of features built into it that make it a very reliable relay. For one, it has an internal fuse to protect against circuit overload. It also features an LED that lights up when the power is on, allowing the user to easily check the power status. In addition, it also has an internal thermal protection device that prevents the relay from overheating.

Finally, the G2R-1-T AC12 also features an optional PTC (positive temperature coefficient) resistor that is used to protect the relay from momentary overloads. This feature is especially useful for protecting the circuit from motor start up surges or large inrush currents.

Conclusion

The G2R-1-T AC12 is a powerful power relay with a rated carry current of over 2 amperes. This single-phase relay can be used in a wide variety of applications ranging from motor control to air conditioning and emergency power supply systems. The G2R-1-T AC12 power relay also features an internal fuse and LED, as well as an optional PTC resistor for overload protection.
