GE IS200ESYSH3ABB ESYS Excitation I/O Terminal Board

Product Description: The IS200ESYSH3ABB is a GE Speedtronic Mark VI EX2100e excitation control system simplex I/O interface terminal board (ESYS). It is the main signal interface for generator PT voltage, CT current, discrete trip contacts and auxiliary analog signals. It transfers field excitation loop signals to the main controller through HSLA / HSSL high-speed serial link daughter card, supporting generator voltage regulation, excitation limit and protection interlock logic. The suffix ABB represents this specific hardware revision variant, widely used for generator static excitation cabinets in combined cycle power plants.

Features:

• Exclusive for GE EX2100e excitation platform, H3 group simplex single-channel control architecture
• Integrates CT (1A/5A) and 3-phase PT transformer isolated measurement inputs
• Supports discrete contact inputs, trip relay outputs and auxiliary analog signal termination
• Requires HSLA high-speed serial daughter board to communicate with the EX2100e main control pack
• Built-in isolation transformers and surge suppression to suppress grid noise and transients
• ABB suffix defines hardware BOM and PCB revision, conformal coating option available
• Eurocard plug-in form factor, installed in Mark VI VME rack, hot-swap capable
• Status LED indicators for power, link and channel fault diagnosis

Applications:

• Thermal power plant EX2100e generator excitation control cabinet
• Combined cycle gas turbine generator voltage regulation and protection system
• Hydroelectric generator static excitation control panel signal termination
• Oil & gas island power generation unit excitation spare replacement
• Legacy Mark VI EX2100e system maintenance and retrofit project

FAQ:

Q: What does ESYS stand for?
A: ESYS = Excitation System I/O Board, dedicated termination interface board for EX2100e excitation control.

Q: What is the difference between IS200ESYSH3ABB and other ESYS revisions?
A: ABB is hardware revision code. Different revisions have component differences; must match the EX2100e firmware version, not directly plug-and-play interchangeable.

Q: Can it work without HSLA daughter card?
A: No. HSLA HSSL serial link sub-board is mandatory for data communication between ESYS and main controller.

Q: Can it be used on Mark VIe EX2100eS?
A: No, this board belongs to classic Mark VI EX2100e, incompatible with Mark VIe IONet architecture.

Q: Is IS200ESYSH3ABB still in production?
A: EX2100e Mark VI series hardware is obsolete. Available stock is NOS surplus or fully tested refurbished boards.
