12HGA11J52
The product is named General Electric 12HGA11J52 Auxiliary Relay Module. General Electric, a globally recognized brand in the electrical and industrial technology domain, manufactures this module.
2. Product Description
2.1 General Function
The 12HGA11J52 is an auxiliary relay module that plays a crucial role in electrical control systems. Its primary function is to act as an intermediary in the control circuit. It receives control signals from a main control source, such as a programmable logic controller (PLC), a control relay, or an operator – interface device. Once it receives the signal, it can then switch or amplify the electrical power to control other electrical devices. This is especially useful in applications where the main control signal does not have sufficient power to directly drive the load, or when isolation between the control circuit and the load circuit is required.
2.2 Key Features
- High – Voltage Coil Operation: The module is designed with a 125V DC coil voltage. This relatively high – voltage operation makes it suitable for use in industrial settings where the electrical systems often operate at such voltage levels. It can effectively respond to control signals within this voltage range, ensuring reliable operation.
- High – Current Handling Capacity: With a continuous current rating of 20A, the 12HGA11J52 can handle substantial electrical loads. This allows it to be used for controlling high – power devices such as large – capacity contactors, solenoid valves, and motors in industrial applications.
- Single – Pole, Double – Throw (SPDT) Contact Configuration: The SPDT contact configuration provides flexibility in circuit design. It has three connection terminals, allowing for two different output states. One of the common applications of this configuration is in circuits where a device needs to be connected to two different power sources or switched between two different operating modes. For example, in a motor – control circuit, it can be used to reverse the di
