The ABB DSSB-01C (68300746) is a high-performance control unit for ACS800-07 drives and ACS800 DSUs, serving as the core interface for managing power circuitry and control logic. It features 16 digital I/O channels and precise analog signal processing capabilities (±0.1% accuracy) to meet complex industrial automation needs. The unit also provides real-time monitoring and supports multiple communication interfaces, including Ethernet and RS-232/485, to enhance diagnostic capabilities.
The DSSB-01C operates with closed-loop feedback, monitoring the DSU input current to detect ground faults. Its microprocessor uses advanced algorithms to process sensor inputs, outputting a 0-24 VDC signal to regulate power components with sub-millisecond response times.
The DSSB-01C 68300746 ABB Control Board for DSU Unit may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

It acquires raw signals from the grid side via current/voltage transformers, and then performs digital processing and algorithm calculations by an internal high-speed microprocessor. Upon system startup, it controls the closing of the pre-charge circuit and main contactor according to a preset timing sequence to prevent large current surges into the DC bus capacitor. During operation, it continuously compares feedback data with set thresholds. Upon detecting parameter deviations or external alarm signals, it immediately disconnects the main circuit or triggers protection logic via an output relay, thereby achieving precise logic control and safety protection for the rectifier power components and downstream inverter system.
The DSSB-01C is designed for heavy industrial environments, providing high-precision power circuit monitoring and management:
ACS800-07 Drive System: Used as a core control component or spare part for various cabinet drives (power range from 45 kW to 2800 kW).
Diode Power Supply Unit (DSU) Control: Manages the three-phase AC-to-DC rectification process, ensuring stable power supply to the intermediate circuits of the inverter unit.
MultiDrive Power Supply Section: Typically integrated into the power supply section of the ACS 600 MultiDrive system to coordinate input power and system safety.
Hazardous Area Operations: Typically included in the ACS800DSUV3 kit for robust power management in demanding industrial process control and motor management applications.
