Description
Product Overview
The ABB DSBC172 is a high-performance bus extender module designed for ABB’s S800 I/O distributed control system, serving as the critical link for expanding communication capabilities in industrial automation setups. Engineered to support MasterBus300 and PROFIBUS DP protocols, the DSBC172 enables seamless data transmission between I/O racks and higher-level controllers like ABB’s AC 800M series, extending the system’s coverage up to 1,200 meters without signal degradation. Unlike standard bus modules, it features dual redundant communication paths with automatic failover, ensuring continuous operation in mission-critical applications such as steel mills or chemical processing plants.
The DSBC172 integrates seamlessly with ABB’s S800 I/O backplane architecture, supporting up to 16 I/O modules per extended rack. Its hot-swappable design allows maintenance without system shutdown, while real-time diagnostics monitor network health, voltage levels, and temperature in harsh environments (-20°C to +60°C). With IP65-rated enclosure and SIL 2 safety integrity level certification, the module is ideal for safety-critical systems requiring high availability and fault tolerance.

Main Features and Advantages
Extended Communication Reach:
The DSBC172 extends the S800 I/O system’s bus length up to 1,200 meters using fiber-optic or twisted-pair cables, making it ideal for large-scale industrial facilities such as automotive assembly lines or offshore platforms. Its signal regeneration technology ensures zero data loss even in high-interference environments, reducing downtime by 40% compared to non-extended systems.

Redundant Architecture:
Dual independent bus interfaces provide seamless failover within 50 milliseconds, critical for 24/7 operations in power generation or wastewater treatment plants. The module’s predictive diagnostics (e.g., cable break detection) alert operators to potential issues before system failures occur, minimizing mean time to repair (MTTR) by 50%.

Modular System Integration:
Compatible with ABB’s DSPC172 backplane and DPW11S power supply, the DSBC172 supports scalable configurations from small panels to multi-rack installations. Its IP65-rated enclosure allows direct installation in dusty or wet environments (e.g., cement plants or food processing lines) without additional protective housing.
