I/O modules

The IS200EROCH1A IS200EROCH1ADD manages exciter field current for synchronous generators.

This board regulates voltage output with high precision. Its rectangular frame measures 230 millimeters in width. The board height reaches 170 millimeters exactly. Depth stays at a compact 25 millimeters. You will find this unit weighs approximately 0.85 kilograms. Therefore, installation requires only four mounting screws. Three terminal blocks serve as main connection points. Each block accepts up to 12 AWG copper wires.

The IS200EROCH1A IS200EROCH1ADD contains exactly 186 discrete components.

A 3300 microfarad capacitor bank stores energy for stable output. This bank filters rectified AC into smooth DC voltage. Six power MOSFETs handle the output switching duties. Each MOSFET can carry up to 25 amperes peak. Four status LEDs monitor regulation and fault conditions. These indicators help you diagnose issues quickly. The board accepts two types of control signals. You can use either 0–10V analog or 4–20mA loop inputs.

This exciter regulator board connects directly to generator field windings.

It maintains constant voltage under varying loads. Moreover, the board includes over‑excitation protection logic. You can adjust PID parameters via onboard potentiometers. The unit also features a built‑in de‑excitation circuit. This circuit safely discharges field energy during shutdowns. Consequently, you protect both generator and exciter components. GE designed this board for harsh power plant environments. Its conformal coating resists moisture and airborne contaminants.

In summary, the IS200EROCH1A IS200EROCH1ADD delivers reliable excitation control. Use this board for turbine generators or large motors. It ensures stable voltage regulation across all operating conditions. Order this exciter board for your power generation system.
