ALSTOM 12004-101-01 SBS Serial Bus Baseplate

ALSTOM 12004-101-01 is an SBS serial bus baseplate for Alstom turbine control system. It acts as the carrier rack to install SBS series I/O modules, distributing 24V DC power and proprietary serial bus signals between main controller and individual I/O cards.

This baseplate adopts RS485 physical layer for SBS bus communication, and provides galvanic isolation to protect circuits from high electromagnetic interference in power plant environment. It supports hot swapping of plug-in I/O modules, widely used as spare replacement for turbine control cabinet maintenance and retrofit projects.
