Description
Product Introduction
⚙️ Product: KSD211B101
🏷️ Part Number: 3BHE022455R1101
🔧 Brand: ABB
🔌 Product Type: Input Coupling Unit (ICU)
The ABB 3BHE022455R1101 is identified in ABB product references as KS D211 B101: Input Coupling Unit ICU, rather than a conventional PCI Express communication board. It belongs to the ABB UNITROL® excitation-system product family and is associated with static excitation systems.
⚡ The unit provides an interface between field-side signals and the associated ABB excitation/control architecture. It is used in industrial power-electronics environments where reliable signal coupling and system interfacing are required.
🏭 The 3BHE022455R1101 is particularly associated with UNITROL 6000 medium static excitation systems. When sourcing a replacement, the complete ordering number should be matched because similar ABB interface and coupling units can have different electrical or system functions.

Installation & Use
🛠️ Before installation, verify KSD211B101 / 3BHE022455R1101 against the existing unit nameplate and system documentation.
🔌 Isolate the associated excitation system before removing the existing unit. Inspect connectors, terminals, wiring, and mounting hardware before installation.
📋 Confirm the signal connections and system configuration before energizing. Do not substitute a visually similar ABB coupling unit without checking the complete part number.
📊 After installation, check system diagnostics, input/output signal transfer, excitation-system communication, and generator-control functions. Perform the required functional checks before returning the excitation system to normal operation.
⚠️ Identification note: although the supplied listing describes this part as an “ABB PCI Express” board, the available ABB product identification for 3BHE022455R1101 points to KSD211B101 / Input Coupling Unit ICU.
