Model: 2UBA004782R0025 Brand: ABB Series: Industrial Drive Spare Parts Core Function: Control interface circuit board for ABB industrial drive system, responsible for signal acquisition, logic processing and internal signal transmission between drive subunits Product Type: Drive Control PCB Board Key Specifications: 24 V DC internal power supply, multi‑channel signal terminals, gold‑plated connectors, conformal coated circuit board, cabinet‑mount installation, industrial grade anti‑interference design
The ABB 2UBA004782R0025 is a dedicated replacement printed circuit board designed for ABB heavy‑duty variable‑frequency drive units. It handles internal signal routing, feedback signal conditioning and inter‑board communication inside the drive cabinet. This board transfers real‑time status signals between power section and main control unit, supports fault detection and alarm signal output. As an obsolete OEM spare component, it is widely used for maintenance, repair and retrofit of existing ABB drive equipment in process‑critical industrial sites.
Series
2UBA‑series boards are ABB original spare PCBs for variable‑speed drive platforms. Each part number corresponds to a specific hardware function including control interface, power feedback, trigger board and signal conditioning board. These conformal coated circuit boards are engineered to withstand high‑vibration, temperature‑fluctuating cabinet environment, and serve as direct replacement components for aging drive hardware.

Function
ABB 2UBA004782R0025 receives feedback signals from drive power units, processes and transmits these signals to the main control board. It routes control commands from main controller to corresponding subunits. The board monitors internal hardware status, triggers fault alarm when abnormal signal occurs, and realizes reliable inter‑module signal interaction inside the frequency converter system.
Purpose
Used to replace failed original circuit board inside ABB industrial drive. Restore normal operation of variable‑speed drive equipment, reduce system downtime for production lines. Mainly applied for equipment maintenance and spare‑part stock for legacy ABB drive installations.
Application Fields
Metallurgical industry, water treatment plants, chemical processing facilities, power plants, mining equipment, paper‑making production lines, heavy‑duty industrial drive maintenance, factory automation retrofit projects.
