ABB AC 800PEC / UNITROL: PCD231B101 (3BHE025541R0101) PEC80-CCI Module

The ABB PCD231B101 (Part Number: 3BHE025541R0101), cataloged as the PEC80-CCI, is an advanced Exciter Control and Communication Interface module. It is a fundamental building block of ABB's high-performance UNITROL® 6000 static excitation systems and the AC 800PEC power electronic control platform.

Working in tandem with the main control module (such as the PCD230A), the PCD231B101 acts as the crucial high-speed interface that translates the controller's rapid calculations into precise, actionable signals for the power electronic converters. In the demanding environment of power generation, where milliseconds dictate grid stability, this module ensures flawless communication and deterministic control over the generator's magnetic field.

Frequently Asked Questions (FAQ)

Q1: How does the PCD231B101 differ from the PCD230A?

A: In the UNITROL 6000 architecture, the PCD230A (CCM) acts as the main processing and measurement brain, while the PCD231B101 (CCI) is the specialized communication and control interface bridging the processor to the field execution hardware.

Q2: Can I hot-swap this module while the generator is online?

A: If your UNITROL 6000 is configured in a fully redundant dual-channel setup, it is often possible to swap a failed module on the standby channel. However, always strictly follow ABB's site-specific operating procedures.

Q3: Does this module require software programming before installation?

A: The PCD231B101 is primarily a hardware interface module. Its behavior is dictated by the firmware loaded into the main AC 800PEC controller, typically making it a direct drop-in replacement.

Q4: How fast is shipping for an emergency outage in Riyadh?

A: We prioritize power generation emergencies. With ready-to-ship stock, express air freight (DHL/FedEx) typically reaches major Middle Eastern hubs in 3–5 business days.
