Overview

The GE IS200EMIOH1ACA Exciter Main I/O Board is designed to serve as the primary interface between the exciter control system and external field devices. It efficiently handles digital inputs, relay outputs, and communication signals, ensuring seamless coordination between terminal boards and control processors.

Moreover, this board supports high-density signal routing and integrates securely into a VME rack configuration. Its robust design includes front-mounted LEDs for power and status indication, helping operators quickly assess system health. In addition to its core I/O functions, the EMIO board plays a vital role in fault detection, system protection, and operational continuity in high-demand industrial environments.

Therefore, the IS200EMIOH1ACA is widely used in gas, steam, and hydroelectric power plants where reliable excitation control is essential for generator performance and safety.

Technical Data

Typical Applications

• Excitation Control Systems: Interfaces with terminal boards to manage exciter enable, field flashing, and trip signals.
