Overview

The GE IS220STAIH2ACB Exciter Analog I/O Terminal Board is designed for use in GE's Mark VIe and EX2100 excitation systems. It provides 16 differential analog input channels, offering flexibility to support various signal types, including:

• 4–20 mA current loops

• ±1 mA, ±5 VDC, ±10 VDC voltage signals

This wide range of supported signals allows it to monitor critical process variables such as temperature, pressure, and flow, making it essential for generator control and protection in power plants.

The board integrates seamlessly with control processors and I/O packs and offers features like onboard diagnostics, jumper-selectable configurations, and DIN rail mounting for easy installation. Additionally, it supports real-time data processing and fault isolation, helping enhance system reliability and performance.

This module is commonly used in gas, steam, and hydroelectric power plants where precise analog input is crucial for safe and efficient generator operation.

Technical Data

Typical Applications

• Excitation System Monitoring: Used for capturing analog signals from sensors to support generator control and protection.

• Industrial Process Control: Interfaces with transmitters that measure temperature, pressure, and flow.

• Power Plant Automation: Essential for real-time analog signal acquisition in gas, steam, and hydroelectric facilities.

• System Diagnostics: Provides fault detection and signal validation, enabling predictive maintenance and reducing system downtime.

• Retrofit Projects: Compatible with legacy Mark VIe installations, making it ideal for modernization and system expansion.

Example: In a hydroelectric plant, the IS220STAIH2ACB board can be used to monitor water flow and turbine pressure through 4–20 mA transmitters, feeding real-time data directly to the excitation controller. Its diagnostic features help operators quickly isolate faults, enhancing system uptime and performance.
