Product Overview

• Part No: UAD206A101, alternative code 3BHE024578R0101
• Brand: ABB

• Category: Signal Processing BoardUAD206A101 is a high-performance signal processing board based on ABB AC800PEC control platform. It is responsible for collecting, conditioning and transmitting analog and digital feedback signals within power electronic systems. The module processes current, voltage measurement signals and interlock status signals, transmits valid data to the main controller, and distributes synchronous control commands to drive boards. It ensures high-precision signal transmission for closed-loop control, acting as an essential signal intermediate unit for generator excitation and medium voltage power conversion devices.
