Technical Specifications Multi‑module slot positions, integrated system signal bus and power distribution traces. Working power transferred from power supply module. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Gold‑plated contact connectors for each slot.
Functional Features Offers mechanical installation slots for various plug‑in control and I/O modules. Routes system communication bus signals among inserted modules. Distributes DC working power from power module to every slot connector. Provides standardized signal interconnection between all rack internal units.
Application Scenarios Back‑plane spare part for ABB old‑generation control rack. Used for cabinet reconstruction and hardware fault replacement.
Performance Parameters Low‑loss bus signal transmission. Reliable power distribution for multi‑slot load. Stable gold‑plated contact conduction performance.
Material Composition Metal rack fixing frame. Multilayer glass‑fiber epoxy back‑plane circuit board. Gold‑plated slot contact assemblies. Screw‑type mechanical fixing components.
Structural Characteristics Horizontal rack‑mount back‑plane assembly. Multiple parallel module slots arranged on front surface. Rear side equipped with fixed mounting holes for rack frame.
Working Principle Power supply module feeds DC power onto back‑plane power traces. Bus signals are routed across internal circuit traces among each slot. When modules are inserted, gold‑plated contacts realize electrical connection for power supply and signal intercommunication.
Installation Requirements Completely cut off rack power supply before replacement. Fasten DSAB‑01C to cabinet rack frame with fixing screws. Check each slot connector for mechanical damage. Insert corresponding modules into slots. Restore power supply and verify bus communication for each module.
Usage Notes Avoid mechanical scratch to gold‑plated contact surfaces. Prevent conductive dust accumulation inside slot sockets. Do not bend circuit board during installation. Verify communication status of all modules after replacement.
