The IS200ERIOH1A is a notable product from GE, which is an essential component in the generator excitation control system. It functions as an input – output interface board, playing a crucial role in the data exchange and control signal transmission within the excitation system.
This board is designed to receive various input signals from different sensors and monitoring devices in the generator and its associated equipment. These input signals can represent electrical parameters such as voltage, current, and frequency, as well as non – electrical parameters like temperature and pressure. After receiving these signals, the IS200ERIOH1A processes them and converts them into a format that can be understood by the main control unit of the excitation system.
On the output side, the board generates control signals based on the instructions from the main control unit. These output signals are used to control different components in the excitation system, such as contactors, relays, and valves. By accurately transmitting and receiving signals, the IS200ERIOH1A helps ensure the stable and efficient operation of the generator’s excitation system, which is vital for maintaining the quality and reliability of the electrical power output.

4. Application Areas and Application Cases
Application Areas: The IS200ERIOH1A is mainly used in power generation facilities, including thermal power plants, hydropower plants, and gas – fired power plants. It is also applicable in industrial settings where large – scale generators are used for self – power generation, such as in large manufacturing plants, refineries, and data centers.
Application Case: In a hydropower plant, the IS200ERIOH1A is installed in the generator’s excitation control system. It receives input signals from sensors that measure the generator’s stator voltage, rotor current, and the temperature of the exciter. After processing these signals, it sends control signals to adjust the field current of the generator through the excitation system. This ensures that the generator maintains a stable output voltage and frequency, even when the water flow through the turbines changes due to seasonal variations or reservoir management.
5. Comparison with Competing Products
Compared to similar products in the market, the IS200ERIOH1A has several advantages. In terms of signal – handling density, it can accommodate more input and output channels in a smaller space, which is beneficial for systems with limited cabinet space. Its accurate signal conversion capabilities provide more reliable data for the control system, leading to better – controlled generator operation. The reliability of the IS200ERIOH1A is superior, with a lower probability of failure and better resistance to environmental factors. Additionally, its flexible configuration options make it easier to adapt to different generator setups and application requirements.
6. Selection Suggestions
Compatibility: Ensure that the IS200ERIOH1A is compatible with your existing generator excitation system. Check the communication interfaces, power supply requirements, and input/output signal types to avoid integration issues.
Performance Requirements: Evaluate your specific application requirements, such as the number of input and output channels needed, the accuracy of signal conversion, and the response time. Make sure the IS200ERIOH1A can meet these performance criteria.
Budget: Consider your budget when selecting the product. While the IS200ERIOH1A offers high – quality performance, it is important to ensure that it fits within your financial constraints.
7. Precautions
Installation: Follow the installation instructions in the product manual carefully. Incorrect wiring, improper grounding, or incorrect mounting can cause damage to the board or lead to signal interference.
Operating Environment: Keep the operating environment of the IS200ERIOH1A within the specified temperature and humidity range. Avoid exposing it to strong electromagnetic interference, corrosive substances, and excessive dust, as these can degrade the performance and lifespan of the board.

Ultra-Low Cost for Budget-Critical Applications: The Motorola MVME162-12’s simplified design (fixed ranges, 10-bit resolution, single-ended inputs) reduces hardware costs by 40% compared to Motorola MVME162-412. For a small organic farm’s irrigation monitoring system, pairing Motorola MVME-201 (8 built-in digital I/O) with Motorola MVME162-12 provides 4 analog inputs (for soil moisture sensors) and 2 analog outputs (for valve positioning)—all at a price point 35% lower than mid-tier analog modules. This affordability lets small operations automate basic analog tasks without overinvesting in unused precision.
Zero Configuration for Fast Deployment: Unlike Motorola MVME162-412 (software-configurable ranges), the Motorola MVME162-12 uses fixed 0–5 VDC input/output ranges—requiring no software setup or calibration tools. For a workshop’s tool cooling system, technicians can wire 4 temperature sensors (0–5 VDC) to the inputs and 2 fan controllers (0–5 VDC) to the outputs, then start using the module immediately via basic VME register reads/writes. This simplicity cuts deployment time by 80% compared to configurable modules, critical for small teams with limited automation expertise.
Compact Design for Chassis Space Efficiency: The Motorola MVME162-12 retains the standard 3U VME form factor of higher-end MVME162 modules but uses a streamlined circuit design to minimize power draw (0.5 A typical vs. 0.8 A for MVME162-412). In a portable test enclosure (e.g., a mobile environmental sensor unit), this low power consumption extends battery life during fieldwork, while the 3U size fits alongside a Motorola MVME-167-01A and a Motorola MVME-050 (digital I/O) in a compact chassis. This space efficiency eliminates the need for larger, costlier enclosures—saving an additional 20% on system hardware.
