ABB PCD231 AC 800PEC Converter Control Interface

The ABB PCD231 (Order Number: 3BHE025541R0101, also designated as PC D231 B) is a Converter Control Interface (CCI) module engineered for ABB AC 800PEC control platforms and UNITROL 6000 X-power excitation systems. It serves as an interface board between high-power converter hardware and central controllers, executing signal acquisition, parameter measurement, and thyristor firing control for industrial power electronics.

Communication and Network Interfaces

The module incorporates robust communication options for multi-axis drive and power management systems. It features a 4-port Ethernet switch interface for network connectivity, an RS-232 serial interface for local control-panel access, and dedicated CAN and RS-485 fieldbus links. An integrated optical module interface provides three optical channels for high-speed, noise-resistant data exchange within power converter assemblies.

I/O Configuration and Measurement

The PCD231 manages extensive input and output signals to monitor and regulate power conversion processes. It includes 11 standard control digital inputs alongside a dedicated pulse-blocking input for emergency shutdown capability, accompanied by 8 digital outputs rated at 24 VDC. For thermal and electrical monitoring, the module provides 8 KTY temperature sensor interfaces and measures active converter variables such as voltage, current, and DC output voltage.
