ABB 3BHE022291R0101 PCD230 A101 UNITROL Communication Control Measurement Module

Description

The ABB 3BHE022291R0101 PCD230 A101 (cataloged as PC D230 A: PEC80-CCM) is a specialized Communication, Control, and Measurement (CCM) module engineered for ABB UNITROL 6000 X-power excitation systems and PEC80 power electronic control architectures. Positioned within the primary control subrack, the module executes high-speed signal processing, excitation parameter acquisition, and control loop synchronization essential for excitation management.

As the central communication and measurement node of the PEC80 system, the PCD230 A101 coordinates data transfer between the central processing infrastructure, Converter Control Interfaces (CCI), and plant-level distributed control systems (DCS). Its dedicated bus architecture handles high-frequency analog and digital field values, enabling precise regulation of generator terminal voltage, reactive power, and field current.

Features

• Dedicated CCM architecture providing simultaneous communication handling, control logic execution, and measurement acquisition.
• Direct backplane bus compatibility with ABB UNITROL 6000 X-power and PEC80-based power electronic assemblies.
• High-speed deterministic data exchange supporting plant network protocols including Ethernet and serial field interfaces.
• Modular rack-mount card format with front-panel diagnostic indicators for system status and bus communication monitoring.
• Field-replaceable unit (FRU) engineering allowing direct mechanical and electrical interchangeability with identical part numbers.

Applications

• Static excitation systems (SES) for utility-scale synchronous generators and synchronous condensers.
• ABB UNITROL 6000 X-power excitation cubicle installations and retrofits.
• Power electronics and drive control systems utilizing PEC80 and 800PEC controller hardware platforms.
