ABB DSBC172 57310001-KD Bus Repeater / Bus Extender Module

Description

Hardware and Performance Specifications Auxiliary supply: Powered by VME rack back‑plane, no external power supply required Power consumption: ≤7 W Supported bus protocol: ABB proprietary MasterBus 300 Function: Bus signal regeneration, electrical‑isolation, bus distance extension Mounting mode: VME Eurocard plug‑in board for Advant subrack Protection class: IP20 Operating temperature: −25 ℃ ~ +70 ℃ Storage temperature: −40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial electromagnetic‑compatibility standards Dimension & weight: approx. 324 × 234 × 22.5 mm, weight approx. 0.40 kg Certifications: CE approval

Main Functions Regenerate and reshape MasterBus 300 bus signals to extend effective communication distance. Provide galvanic isolation between different bus segments to suppress ground‑loop interference. Support multi‑cluster S800 I/O subrack cascading connection within Advant DCS system. Detect bus communication errors and segment fault status. Front‑panel LED indicators display power‑on status, bus activity and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and bus segment failures, and reports fault information to the main controller. Parameter configuration and bus diagnosis are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Bus communication cables shall adopt shielded twisted‑pair and be strictly separated from high‑power power cables. Ensure reliable cabinet protective grounding. After module replacement, confirm full part‑number DSBC172 / 57310001‑KD matches original project configuration. Perform bus segment communication test and verify data exchange between controller and distributed I/O clusters. Different hardware revisions cannot be directly interchanged without configuration adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Bus‑repeater‑module spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for distributed S800 I/O bus extension in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.
