Description
The ABB APBU-44C is a PPCS Branching and Datalogger Unit designed for the ACS800 Multidrive system. The APBU-44C is used to implement the parallel connection of multiple ACS800 series inverter or supply modules, enabling efficient power distribution and centralized monitoring in industrial drive applications.
The ABB APBU-44C has connections for four inverter or supply modules, as designated by the "44" in the model number. The APBU-44C is connected in the PPCS fibre optic link between the RDCU drive control unit and the modules, facilitating high-speed, noise-free communication over fiber optic cables.
The ABB APBU-44C contains an integrated datalogger for collecting and storing real-time data from the module power stages. The APBU-44C datalogger helps with fault tracing and analysis, providing valuable diagnostic information for maintenance personnel to identify and resolve system issues.

Features:
- ABB ACS800 multi-drive branching unit
- PPCS fiber optic communication distribution
- Integrated communication branching architecture
- Compatible with RDUC drive control units
The unit is installed between the RDUC drive control unit and connected power modules, providing communication branching for up to four inverter or power modules through the ABB PPCS fiber optic network. This configuration simplifies communication architecture while maintaining reliable data exchange between the control unit and connected drive modules.
The APBU-44C ABB BRANCHING UNIT may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The APBU-44C is a DIN rail-mountable unit requiring an external 24 V DC power source connected to terminal X1. Power consumption does not exceed 15 W. It is connected in the PPCS fibre optic link between the RDCU drive control unit and the modules. The standard APBU-44C provides connections for four inverter or supply modules via fibre optic channels V1 through V14.
Configuration is performed via DIP switches: S1 and S2 set the DDCS node address, and S3 selects the operational mode. A memory backup battery (actuator 6) maintains datalogger memory contents during power loss. Status LEDs indicate power (PWR), battery condition (BAT), and fibre optic data transmission (TXD) and reception (RXD).
- Heavy Manufacturing: Synchronizes multiple high-power motors in rolling mills, extruders, and conveyors
- Oil/Gas/Mining: Controls high-torque pumps, compressors, hoists, and drilling equipment
- Energy/Power: Integrates wind/solar converters and grid/rotor-side modules with parallel connections
- Marine/Offshore: Manages propulsion drives, thrusters, and heavy winches on ships
- Water/Wastewater: Regulates distributed I/O and high-voltage pump stations

Cable Type: Use plastic optical fiber (POF) cables for standard links up to 10 meters, or Hard Clad Silica (HCS) cables for longer runs.
Transceiver Match: Connect the transmitter terminal (TX) of the sending board to the receiver terminal (RX) of the receiving board.
Channel Assignment: Link your parallel inverter modules sequentially starting from Channel 1 to maintain clear system diagnostics.
Technical notes
The ABB APBU-44C is a DIN rail-mountable unit, providing space-efficient installation in control cabinets. The APBU-44C requires an external 24V DC power source via the X1 terminal block. The APBU-44C features DDCS address setting via switches S1 and S2, with a mode switch S3 for configuration, enabling flexible addressing in the PPCS fiber optic communication network.
FAQs
