ABB DSBC170 57310256-DB Advant Master Bus Module

ABB DSBC170 Master Bus Module

The ABB DSBC170 (part number 57310256-DB) is a master bus communication module designed for ABB MasterPiece 200 and Advant Master DCS control systems. It acts as a primary communication interface within system subracks, driving master bus communication and enabling high-speed data exchange between central processing units and distributed I/O racks.

System Architecture and Bus Interface

The module operates as a core communication interface on the ABB Master bus network. Installed into dedicated subrack positions, it establishes synchronous data communication links across backplane assemblies to coordinate process data transfer between controllers and field interface units.

Hardware Configuration and Mounting

Designed in a standard ABB Master rack-mounting form factor, the board connects directly to the system backplane via multi-pin edge connectors. Its hardware assembly features onboard status indicators for real-time diagnostic monitoring of bus communication activity and module status during operation.
