ABB DSSB140 Bus Supervisor Board

Technical Specifications Model: DSSB140 System Compatibility: ABB Advant Master DCS System Bus Interface: Advant Master internal backplane bus Mounting: Eurocard controller rack plug‑in Power Supply: From controller rack backplane Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE

Functional Features Real‑time monitoring of internal backplane bus data transmission status inside controller rack. Implements bus arbitration mechanism to resolve bus access conflict between multiple modules. Detects bus communication error, signal distortion and bus hardware failure. Transmits bus fault alarm information to main processor board. Front‑panel LED indicators display bus running status and fault alarm state. Supports hot‑swap operation under authorized Advant Master maintenance workflow.

Application Scenarios DSSB140 bus supervisor board spare‑part replacement for Advant Master controller rack. Internal bus communication monitoring and management for legacy ABB DCS control system. DCS system troubleshooting and hardware overhaul maintenance projects.

Performance Parameters Bus monitoring cycle complies with Advant Master bus timing specification MTBF: 208000 hours Shock and Vibration: Complies with IEC 60068‑2‑6

Installation Requirements Insert DSSB140 fully into target controller rack slot and tighten front locking screw. Confirm backplane connector is completely engaged without poor contact. Complete protective earthing according to Advant Master system grounding specification. Reserve ventilation heat‑dissipation space around board slot. Ambient operating temperature shall keep within 0 ℃ ~ +60 ℃ without condensation. Verify system bus communication function after hardware installation completion.
