Description
The part numbers IS200AEPCH1ACC and IS215AEPCH1DB represent closely related hardware iterations of a specialized control board module used within General Electric’s industrial and renewable energy automation platforms.
Product Overview
-
Manufacturer: General Electric (GE) / GE Vernova / Emerson
-
Part Numbers:
-
IS200AEPCH1ACC (Base circuit board / card component designation)
-
IS215AEPCH1DB (Fully assembled functional unit / packed version, often superseding earlier “H1A” or “H1C” revisions)
-
-
Component Type: AEPC Wind Pitch Center Control Board / Application Control Processor (ACP)
-
Platform: GE Mark VI / Mark VIe Distributed Control System (DCS) / Mark VIe Wind Power Control Architecture
Key Specifications & Features
-
Primary Function: Acts as the Non-ESS Wind Pitch Center Control Board (AEPC module), responsible for managing the central pitch control systems, communication pathways, and coordinated angle adjustments for wind turbine blades.
-
Processor Integration: Utilizes an integrated internal processor board structure (such as pairing with the BPPC processor architecture) to process real-time control commands and feedback loops.
-
Software Compatibility: Requires configuration and programming via GE’s ControlST software suite (typically version 4.06 or later for the later ‘D’-suffix revisions).
-
Communication & I/O: Features robust onboard networking ports (such as Ethernet support for IONet/UDH integration) and serial communication lines (like RS-422) to tie the pitch center hub securely into the broader turbine controller layout.
Industrial Deployment
-
Applications: Widely deployed across utility-scale wind turbine generation farms running the GE Mark VIe control infrastructure, specifically dedicated to regulating blade pitch mechanisms for optimal power generation and emergency feathering safety.
