The SDCS‑CON‑3A is a control and interface board developed for ABB’s DCS 600 / DCS 800 series drive control architecture. It serves as a central logic module coordinating internal drive control electronics, I/O channels, communication links (including optical bus) and diagnostic functions.
In the drive rack, the SDCS‑CON‑3A handles control commands, system logic, feedback loops and communication between the converter modules and higher‑level automation systems. It is built for heavy duty industrial use where reliability, integration and modular replacement capability are required. Its design emphasises compact installation, robust performance and compatibility within the DCS modular ecosystem.
This board is widely used for motor drive control systems in manufacturing plants, process industries, marine/offshore drives and retrofit installations where modular control boards deliver high uptime and simplified maintenance.
