Products Description
The ABB DSBC110 57310256-E is a Profibus-DP Bus Termination Module (also referred to as a bus matching module or repeater board) designed specifically for the ABB Advant OCS and System 800xA legacy platform bus systems .
As a physical layer key component for Profibus-DP networks, this module provides built-in terminal resistance at the beginning and end of linear bus segments to suppress signal reflections and ensure stable communication. When the main controller is located at the bus endpoint, the DSBC110 must be installed on the bus connector to match the cable impedance, preventing data packet collisions and bit errors caused by impedance discontinuities .
This product serves as a critical spare part for the maintenance, expansion, and troubleshooting of legacy ABB distributed control systems, addressing common issues such as communication fluctuations, bit errors, and network interruptions .
