Description
PCD230 PCD230A 3BHE022291R0101 ABB Controller
PCD230/PCD230A (material number 3BHE022291R0101) is the main processor module in the ABB AC 800PEC/Advant Controller 800xA distributed control system, also known as the Communication Measurement Control Board (CCM module). It is not simply an I/O module or communication module, but a core computing unit that integrates real-time measurement, multi protocol communication, and precision control. It simultaneously plays the triple roles of “eyes”, “mouth”, and “brain” in the system.
core positioning
This module is the control center of the AC 800PEC system, responsible for data acquisition and processing, control logic operations, historical data recording, and communication scheduling with the upper system. In the power industry, it is also used as an excitation regulator measurement board, which accurately controls the excitation current and ensures the stable operation of the power grid by monitoring key parameters such as voltage, current, and power factor of the generator in real time. Special attention should be paid: There is a product on the market called “PCD230 Pillow Tension Gauge” used for tension measurement in the paper/film industry, which is completely different from this communication measurement board. When purchasing, be sure to check the order number 3BHE022291R0101.

computing power
Equipped with a 600MHz RISC processor and a 64 bit IEEE 754 floating-point unit (FPU), optimized for applications with extremely fast control cycles. The shortest control cycle can reach 100 microseconds, supporting multi task parallel processing and managing multiple I/O channels and communication protocols simultaneously. The memory configuration varies depending on the model, with a typical 256MB RAM and up to 1MB of logical memory. It supports model-based design using MATLAB/Simulink, and the code can be automatically generated from the model and downloaded directly without manual interaction.
communication interface
The motherboard is equipped with two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, and two RJ45 serial ports (COM3, COM4), where COM3 is an RS-232C port with modem control signals, and COM4 is an isolated port for connecting configuration tools. Supports various industrial protocols such as Ethernet, Modbus TCP, Profibus, Profinet, and Anybus, and can seamlessly integrate with DCS, PLC, HMI, and third-party systems. Supports up to 36 bidirectional fiber optic links, capable of connecting a large number of distributed I/O modules. Fiber optic direct connections do not require additional switches, significantly reducing cabling costs.
Electrical Characteristics
The working power supply is DC 9-36V ultra wide range input, supporting dual power redundancy and automatic switching in case of any fault. Equipped with voltage isolation, reverse connection protection, 80V surge protection, overvoltage protection (OVP), undervoltage protection (UVP), and overcurrent protection (OCP) functions. Extremely low power consumption, can operate without forced cooling. The module implements electrical isolation of no less than 2.5kV between the computing side and the I/O side, effectively blocking on-site grounding circuits and transient interference. Automatically detect the electrical ID of the module when powered on, and refuse to enter the running state when it does not match the system configuration.
Physical specifications
Standard printed circuit board, installed in the AC 800PEC system rack. The onboard LED indicator lights display real-time power status, communication activity, hard disk read/write, and fault conditions, and support remote web server viewing of status and diagnostic logs. Support hot plugging, replacement during operation does not affect the system. The working temperature range is -40 ° C to+75 ° C, the protection level is IP20 (some models can reach IP67), and the working humidity is 5%~95% RH (non condensing). Compliant with industrial grade EMC certification, with strong resistance to electromagnetic interference.
Redundancy capability
Support CPU redundancy, communication redundancy, and dual power redundancy triple redundancy architecture, ensuring system availability of over 99.9% in industries such as power and chemical engineering that require high continuity. Built in real-time self diagnostic function, fault codes can be located at the channel level.
Programming and Compatibility
Compliant with IEC 61131-3 standard, supporting programming languages such as ladder diagram (LD), functional block diagram (FBD), structured text (ST), etc. Compatible with ABB Control Builder/Automation Builder development environment, and can also generate control code directly using MATLAB/Simulink. Fully integrated into the ABB System 800xA architecture, supporting FPGA flexible configuration protocols and application functions without adding additional processor load.
Typical Applications
Generator excitation control and unit monitoring for power generation (gas, steam, hydro), with a response speed of 100 μ s that can be adjusted instantly during grid fluctuations; Remote control of DCS and pipeline valves in petrochemical refineries, suitable for harsh environments with a wide temperature range of -40~+75 ° C; Control of rolling mills and monitoring of blast furnaces in the metallurgical industry, with 36 fiber optic links supporting a large number of I/O point extensions; Remote monitoring and dosing control of water treatment/environmental protection pumping stations; Subway power supply and railway signal control for traffic traction, anti vibration and anti impact design.
