Technical Specifications Rack back‑plane bus connector, fieldbus wiring terminals, module clamping and locking structure. Operating power supplied by rack back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%.
Functional Features Provides fixed installation base for matching fieldbus communication module. Realizes electrical connection between communication module and rack back‑plane bus. Provides screw‑type terminals for external fieldbus cable wiring. Supports module replacement without removing fieldbus cable.
Application Scenarios Spare fieldbus terminal base for ABB DCS control rack. Applied in industrial fieldbus networking and cabinet maintenance project.
Performance Parameters Stable fieldbus signal transmission performance. Reliable back‑plane bus connection characteristic.
Material Composition Flame‑retardant plastic base housing. Multilayer glass‑fiber epoxy printed circuit board. Rack back‑plane plug‑in connector, fieldbus screw‑type terminals and module locking mechanical structure.
Structural Characteristics Standard rack plug‑in base structure. Rear connector connects to rack back‑plane bus. Metal locking screw for rack slot fixing.
Working Principle TB711FC1 is inserted into control rack slot and connected to back‑plane bus. After communication module is installed on base, module exchanges data with rack CPU through base and back‑plane bus. External fieldbus cable connects to screw terminals of base, and signal transmits to communication module through internal circuit.
Installation Requirements Install matched fieldbus communication module and lock. Connect fieldbus cable to front‑panel screw terminals. Restore rack power supply, download communication configuration parameters, verify fieldbus data exchange function.
