IS200AEPCH2CDC — GE Speedtronic Mark VI / Mark VIe AEPC Board
The IS200AEPCH2CDC is a printed circuit board from GE's Speedtronic Mark VI / Mark VIe turbine control system, belonging to the IS200 board family. It is an AEPC-type module — a VME-format card that mounts in the turbine control cabinet rack and serves within the system's interface and control electronics layer.
The Mark VI and Mark VIe platforms are GE's turbine control systems, used to govern gas and steam turbines in power generation and industrial drive applications. Boards in the IS200 series act as the interface between the control processors and the field devices — sensors, transducers, and actuators. The IS200AEPCH2CDC carries the "H2" board designation and a "CDC" revision suffix, distinguishing it from related AEPC variants.

Product Functions
- Control & interface electronics: Provides control and interface functions within the Mark VI/VIe turbine control cabinet, forming part of the system's processing chain.
- Signal handling: Supports the acquisition and processing of field signals used by the turbine control loop.
- System integration: Operates as part of the modular IS200 board set, coordinating with other controller and I/O boards via the backplane.
- Turbine control support: Contributes to the monitoring and control functions essential to gas and steam turbine operation.
- Rack-mounted modular design: As a VME-format card it slots into the control cabinet rack, allowing board-level replacement during maintenance without full system rewiring.
- System lifecycle support: Keeps existing Mark VI/VIe installations operational, supporting spares strategies for ageing turbine control systems.
Application Scenarios
- Gas turbine control: Control electronics within Mark VI/VIe cabinets for gas turbine governor, sequencing, and protection systems.
- Steam turbine control: Control and interface functions in steam turbine control applications.
- Power generation plants: Keeps legacy Mark VI/VIe turbine controls serviceable in utilities managing long-life assets.
- Oil & gas facilities: Support for turbine-driven compressors and mechanical drive applications under Mark VI/VIe control.
- Maintenance & overhaul: Sourced as a spare during scheduled outages to minimise downtime and rewiring effort.
- Legacy system lifecycle support: Supports spares and phased modernization strategies for plants still running Mark VI/VIe controls.
Frequently Asked Questions
What is the IS200AEPCH2CDC?
It is an AEPC-type printed circuit board from GE's Speedtronic Mark VI / Mark VIe turbine control system (IS200 board family), mounted in the control cabinet rack.
Which systems is it compatible with?
It is designed for GE Speedtronic Mark VI and Mark VIe turbine control systems. It is not intended for Mark I, II, or V platforms or other unrelated control systems. Confirm the "H2" designation and revision suffix match your system.
How does it differ from other AEPC variants?
The AEPC family includes several variants differentiated by board designation and revision suffix. The IS200AEPCH2CDC is defined by its H2 designation and "CDC" suffix, so always match the complete part number to your requirement.
What technical details should I confirm before buying?
Channel count, signal type, voltage ratings, dimensions, and connector configuration should be confirmed against the board label or GE documentation. Details vary between revisions and are not consistently published, so verification ensures a correct match.
Is it still available?
The Mark VI/VIe platform is a mature product. Boards in the IS200 series are generally available through GE and industrial spare-parts / repair specialists. Contact your supplier for current availability and lead time.
What should I verify before ordering a replacement?
Match the complete part number including the revision suffix, confirm the board designation corresponds to your cabinet position, and verify compatibility with your Mark VI/VIe firmware and system documentation. Providing a photo of the existing board to your supplier helps ensure a correct match.
