APBU-44C 64669982 | ABB PPCS Fibre Optic Branching & Data Logging Unit
The ABB APBU-44C 64669982 is a PPCS fibre optic branching and data logging unit used in ABB ACS800 multi-axis drive systems. It distributes DDCS/PPCS fibre optic communication between the RDCU drive control unit and individual inverter or supply modules, and can collect and store operational data for monitoring and analysis.
This unit is typically DIN-rail mounted and requires an external 24 V DC control supply. The APBU-44C supports connection to up to four inverter or supply modules, while the APBU-44CE variant can support more channels. Because the suffix after the part number may vary, the exact hardware version, firmware, installed options and compatible drive configuration should be verified with the product nameplate or official ABB documentation before purchase.
