Product Description

ABB DSBC170 | Advant OCS Master Bus Communication Module

High-Speed Bus Repeater for Reliable Data Exchange in Distributed Control Systems

1. Product Overview

The ABB DSBC170 is a high-performance master bus communication module and bus repeater engineered for ABB Advant OCS distributed control systems, serving as a critical interface to enable seamless and high-speed data transmission between controllers, I/O modules, and field devices in industrial automation networks. It features robust bus signal repeating capability with 2500V AC isolation between bus segments, supporting the Advant Master Bus protocol for deterministic data exchange, ensuring reliable communication even in noisy industrial environments with long cable runs or multiple network nodes. Equipped with LED status indicators for bus activity, error detection, and power supply, it facilitates quick troubleshooting and system monitoring, making it an essential component for maintaining operational continuity in process control, power generation, and manufacturing automation applications.
