Product Introduction

The ABB UCD240A101, part number 3BHE022287R0101, is the CCM6080 central control module for ABB UNITROL6000 generator excitation system and AC800PEC high-speed power electronics control platform. It acts as the main arithmetic and communication core of the excitation cabinet, performing automatic voltage regulation, reactive power control, interlock logic processing, fault diagnosis and multi-device data exchange. With high-performance processor and multi-channel communication interfaces, it realizes millisecond-level closed-loop regulation for synchronous generator excitation. Featuring galvanic isolation and heavy-duty EMC protection, the module operates reliably under harsh power plant environments with vibration, temperature variation and strong electromagnetic interference. Widely applied in hydroelectric, thermal and gas turbine generator sets. It is a core spare part for UNITROL6000 cabinet overhaul and main control board replacement.

Content Details

Brand: ABB Model: UCD240A101 Part No: 3BHE022287R0101 Product Type: CCM6080 Central Control Module Applicable System: UNITROL6000 Excitation System, AC800PEC Power Supply: 24VDC Communication Interfaces: Ethernet, CAN, serial ports and high-speed fiber links The ABB UCD240A101 3BHE022287R0101 is rack-mounted inside UNITROL6000 excitation cabinet. It collects generator terminal voltage, stator current, rotor current and grid frequency signals, executes AVR regulation algorithm and sends control instructions to pulse trigger modules. It supports multiple operation modes including constant voltage, constant reactive power and constant power factor, and handles unit startup, grid connection and fault protection logic. It exchanges real-time operating data, alarm events and diagnostic information with upper DCS/HMI via Ethernet and fieldbus. The module integrates comprehensive self-diagnosis and protection functions, including overexcitation, underexcitation, overcurrent and loss of field protection. Every unit undergoes full functional testing and aging screening before shipment to ensure stable 24/7 continuous operation. Built-in galvanic isolation between communication ports suppresses surge and ground loop interference to protect the core control circuit. LED indicators on the front panel display power status, running mode, communication link and fault alarms, helping maintenance engineers quickly locate hardware, signal or communication faults and reduce generator outage time. Typical application scenarios include thermal power generator excitation control, hydropower unit voltage regulation, gas turbine generator excitation and power plant excitation system retrofit. When the original central control module fails, UCD240A101 3BHE022287R0101 can be directly replaced to restore full closed-loop excitation control of the UNITROL6000 system. This module complies with IEC, CE and UL industrial safety and EMC standards with IP20 protection rating. Compact Eurocard rack layout and high-quality industrial components support long-term stable heavy-duty operation. Whether you prepare spare inventory for power plant overhaul or purchase components for excitation system upgrade projects, the ABB UCD240A101 central control module provides dependable core control for your UNITROL6000 excitation system.
