GE IS200AEPAH1AFD  IS210BPPBH2CAA – Matched Excitation/Backplane Modules for Mark VI/VIe Control Cabinets

This pairing is typically used in GE Mark VI/VIe turbine and generator control architectures. The IS200AEPAH1AFD acts as an exciter/analog interface board, while the IS210BPPBH2CAA functions as a power/backplane distribution module inside the cabinet. From my experience, teams reach for this set when they need a drop-in, like-for-like replacement that preserves wiring, I/O mapping, and cabinet layout with minimal commissioning time.

Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock items; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express delivery: FedEx, UPS, DHL

Key Features

• Designed for GE Mark VI/VIe – Compatible form factor and connectors for standard GE control cabinets, which usually means less rework in the field.
• IS200AEPAH1AFD (AEPA) – Excitation/analog interface module handling field feedback and control signals to the exciter power section.
• IS210BPPBH2CAA (BPPB) – Backplane/power distribution module that routes control power and signals across the rack; no external networking required.
• Backplane/VME-style integration – You might notice that both boards rely on the cabinet backplane for power and data, keeping wiring neat and serviceable.
• Service-friendly – Plug-in replacement approach makes swap-outs fast; typically no panel drilling or harness modification.
• Stable in harsh environments – Specified for industrial ambient ranges commonly seen in turbine halls and generator rooms.

Technical Specifications

Application Fields

These modules show up in gas turbine, steam turbine, and generator excitation systems where GE Mark VI/VIe controls are installed. In many cases you’ll see AEPA used to process field feedback and command the exciter bridge, while BPPB routes control power and signals in the same cabinet. Typical sites include combined-cycle plants, cogeneration units, and utility-scale generator rooms where uptime and predictable spares make the difference during peak season.

Advantages & Value

• Reliability in known fleets – Field-proven in GE Mark VI/VIe cabinets; operators often report stable behavior after a simple swap and check.
• Compatibility – Fits existing backplanes and wiring, typically avoiding software or mechanical changes.
• Faster recovery – When a trip or diagnostic fault points at the exciter interface or power backplane, this pair helps restore service without redesign.
• Cost control – Reduces engineering hours and unnecessary re-qualification, especially compared to redesigning I/O paths.
• Support – We can share handling notes and test logs on request; one thing I appreciate is how straightforward the acceptance checks usually are.

Installation & Maintenance

• Environment – Install in a clean, ventilated control cabinet. Maintain ambient within 0–60 °C and avoid condensation.
• Power & wiring – Provide stable 24 VDC control power (cabinet standard). Verify backplane connectors are seated; torque terminal screws per cabinet spec.
• ESD safety – Use wrist straps and antistatic handling. Seat the board vertically and evenly to prevent bent pins.
• Commissioning – After replacement, run cabinet self-tests, verify exciter feedback scaling, and confirm alarms/DI status clear. In most cases no firmware loading is needed for BPPB.
• Routine care – Annual visual inspection, light dust removal with dry air, check for hot spots or loosened connectors. Document any parameter changes.

Quality & Certifications

• Typically used within CE-marked GE Mark VI/VIe systems; UL/CSA conformance applies at cabinet/system level.
• RoHS status may vary by date code and revision; we can check the specific lot on request.
• Warranty: 365 days standard coverage from shipment.
