HIER460302R1 UN0824B-P V1 ABB Analog Input/Output Module

more description

The ABB HIER460302R1 UN0824B-P V1 is vital for controlling the voltage and reactive power of synchronous generators and motors in various power generation and industrial applications.This module acts as a critical interface, acquiring analog signals from sensors (e.g., voltage, current, temperature from the generator or associated equipment) and outputting analog control signals to actuators within the excitation system. Its high precision ensures accurate data acquisition and precise control of the excitation current, which directly impacts the stability and efficiency of the synchronous machine.

feature

Dual Analog Functionality: It combines both analog input and analog output capabilities within a single module. This integration allows for comprehensive feedback (reading sensor data) and direct control (sending command signals) within the excitation loop.

Dedicated for Unitrol Excitation Systems: This module is purpose-built to integrate seamlessly into the ABB Unitrol system architecture.

Temperature Extremes: Capable of operating reliably across a broad industrial temperature range.

application

Synchronous Generator Excitation Control: This is the primary application. The module reads generator voltage, current, and potentially other parameters and outputs precise analog control signals to the exciter to regulate the generator's output voltage and reactive power. 

Renewable Energy Grid Integration: In some larger renewable energy plants (e.g., large wind farms with synchronous generators, or hybrid plants), it can be used for grid stabilization and reactive power compensation.
