GE 12HFA51A42H | Auxiliary Relay | 125VDC

In stock

The 12HFA51A42H is a single-board design that includes the following components:

A digital-to-analog converter (DAC)
An isolation transformer
A power supply
A control interface

The DAC converts the digital output of the ECU to an analog signal that can be used to control the excitation system. The isolation transformer isolates the ECU from the excitation system to prevent damage to the ECU from electrical noise. The power supply provides power to the board and the control interface. The control interface provides a connection to the Excitation Control Unit and the excitation system.

The 12HFA51A42H is a reliable and efficient converter board that is used in a variety of applications, including power generation, industrial control, and transportation.

product description：

GE 12HFA51A42H | Auxiliary Relay | 125VDC.Here are some key points about auxiliary relays: They are commonly used in industrial applications, such as power distribution systems, motor control circuits, and process control systems. They can be used to provide additional contacts for switching higher currents or voltages than the control circuit can handle directly. They can be used to provide isolation between different circuits, allowing for safer operation and troubleshooting. They can be used to perform specific functions, such as time delay, sequencing, or logic operations. They are typically controlled by a separate control circuit, which can be a manual switch, a PLC (Programmable Logic Controller), or other control devices.
