Product Overview

The IS200EAUXH1ABB is a TMR‑compliant exciter auxiliary I/O interface board for GE EX2100e static excitation systems integrated with Mark VIe turbine‑generator control platforms. It handles auxiliary discrete input signals and contactor control interfaces between excitation cabinet field hardware and the main exciter DSPX controller.

This board performs contact signal conditioning, noise filtering, contact status acquisition and contactor driving logic. It transmits real‑time auxiliary status data via the HSSL serial bus to the main exciter controller for generator excitation logic, interlock protection and fault alarm processing. The ABB hardware revision features conformal coating, improving resistance against humidity, dust and mild corrosive gas in power‑plant cabinet environments. It is an ESD‑sensitive VME‑format circuit board designed for rack‑backplane installation inside the EX2100e excitation control cabinet.

Application Notes

• Exclusively applied for GE EX2100 / EX2100e excitation systems under Mark VIe turbine‑generator control system.
• Must pair with DSPX exciter controller via HSSL serial communication link.
• Strict ESD protection required; anti‑static wrist straps must be used for handling and replacement.
• Not hot‑swappable with excitation system live; cut off all cabinet power before servicing.
• Install in climate‑controlled industrial cabinet; avoid condensation, dust and corrosive gas exposure.
• Verify hardware revision compatibility during spare‑part replacement; mixed revisions may affect TMR voting performance.
• Follow GE official EX2100e service manual for wiring and commissioning.
• OEM manufacturing discontinued; supplied as refurbished / surplus spare part for combined‑cycle power plants, thermal power stations and gas‑turbine generator excitation cabinet maintenance and retrofits.
