Overview

The ABB DSSB145 is a high-efficiency DC/DC converter board designed for ABB’s MasterPiece 200 and Advant OCS control systems. It converts a 220V input to stable, regulated DC outputs for automation modules, ensuring reliable performance in demanding industrial environments.

This board supports PROFIBUS DP and PA communication, allowing integration with remote I/O, motor control centers, and field devices. In addition, it features 16MB of programmable memory and dual I/O points, offering flexible deployment across diverse control architectures. Its compact, rugged design allows installation in tight control cabinets and high-temperature zones.

For example, in a power plant DCS, the DSSB145 supplies isolated DC power to control modules while communicating with field instruments over PROFIBUS.
