GE IS200ACLEH1BCB AC Line Excitation Board – Mark VIe Turbine Control System
When an AC line excitation board fails inside a GE Mark VIe turbine control cabinet, the consequences are immediate and severe: the generator loses voltage regulation, excitation collapses, and the unit trips offline. For power plants operating on tight dispatch schedules, even a two-hour unplanned outage can translate into hundreds of thousands of dollars in lost generation revenue and grid stability penalties. The IS200ACLEH1BCB — paired with its daughter card IS215ACLEH1BC — is the precision interface that prevents this scenario, continuously conditioning and routing AC line signals to the excitation control loop with the reliability that critical baseload and peaking generation assets demand.
Within GE’s Mark VIe ecosystem, the IS200ACLEH1BCB occupies a specialized but indispensable role. Unlike general-purpose I/O boards, this module is purpose-engineered for AC line sensing and excitation feedback in GE’s EX2100 and LCI excitation platforms. It is deployed globally across gas turbines, steam turbines, and hydro generators where GE Mark VIe serves as the primary control architecture — a footprint spanning thousands of units across six continents. Its continued availability as a spare part is a strategic necessity for any plant maintenance program built around long-term asset reliability.

Frequently Asked Questions
Q: Is the IS200ACLEH1BCB compatible with both TMR and Simplex Mark VIe configurations?
A: Yes. The board functions in both Triple Modular Redundant (TMR) and Simplex Mark VIe architectures, though slot assignment and I/O mapping must be verified against your specific system configuration file.
Q: Do I need to order IS200ACLEH1BCB and IS215ACLEH1BC together?
A: In most installations, yes — the IS215ACLEH1BC daughter card is required for full functionality. Konmask.com can supply both as a matched set. Please specify your requirement when inquiring.
Q: What is the lead time for this part?
A: Lead time depends on current stock status. In-stock units ship within 3 business days. For sourced units, typical lead time is 2–4 weeks. Contact us for real-time availability.
Q: Can Konmask.com provide a certificate of conformance or test report?
A: Yes. Test reports and certificates of conformance are available for refurbished units upon request. New surplus units can be supplied with original GE packaging and documentation where available.
Q: Do you ship to the Middle East, Southeast Asia, or Europe?
A: Yes. We ship globally via DHL, FedEx, and UPS with full export documentation including commercial invoice, packing list, and certificate of origin where required.
