ABB DSSB 145 DC Converter Board

Quick Overview

The DSSB145 is a high-efficiency DC/DC Converter Board specifically engineered for ABB MasterPiece 200 and Advant OCS control systems. It acts as a critical power regulation hub, converting a 220V input into stable, regulated DC outputs required by sensitive automation modules. Beyond power conversion, the DSSB145 is a multifunctional component featuring PROFIBUS DP and PA communication capabilities and 16MB of programmable memory, enabling it to bridge the gap between power supply and field device integration in complex industrial architectures.

Key Features

• Integrated Power & Communication: Combines a robust DC/DC converter with PROFIBUS DP/PA interfaces, allowing the board to power control modules while simultaneously managing data exchange with motor control centers and remote I/O.

• Programmable Versatility: Equipped with 16MB of memory, the board can be programmed to handle specific control logic or communication routing, offering more flexibility than standard passive converter units.

• Rugged Thermal Design: Built to operate reliably in high-temperature zones and unconditioned control cabinets typical of power plants and chemical processing facilities.

• Galvanic Isolation: Provides isolated DC power to eliminate electrical noise and protect the MasterPiece 200 CPU and I/O modules from input-side surges.

• Compact Footprint: Measuring only 12 x 10 cm, the board is designed for high-density installation in tight control racks where space is at a premium.

• Modern Retrofit Ready: An ideal choice for upgrading legacy Advant OCS systems, replacing older converter boards with a more reliable, programmable, and communication-capable unit.
