Technical Specifications Back‑plane controller bus interface, AF100 fieldbus port. Auxiliary power 24 V DC, typical power consumption 4.4 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Supports multi‑station AF100 bus expansion.
Functional Features Communicates with controller through back‑plane bus. Executes AF100 fieldbus protocol processing. Collects measurement and status data from distributed S800 I/O stations. Transmits control output commands from controller to remote I/O modules. Front‑panel LED shows AF100 bus link and module fault status. Built‑in hardware self‑diagnosis detects fieldbus interruption and internal hardware faults.
Application Scenarios AF100 bus communication spare part for ABB 800xA DCS system. Widely used in distributed remote I/O control projects of process industry.
Performance Parameters Reliable AF100 bus real‑time data transmission. Supports multi‑node remote I/O expansion. Fast bus fault detection response.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. AF100 protocol processing and signal driving assemblies. Back‑plane plug‑in connector and AF100 fieldbus port.
Structural Characteristics Standard controller rack plug‑in module. Front side fitted with AF100 bus port and status LED indicators. Rear side equipped with back‑plane bus connector. Weight approximately 0.42 kilogram.
Working Principle After power‑on initialization, module communicates with each remote S800 I/O station via AF100 bus. It collects field I/O data and uploads to controller through back‑plane bus. Controller output commands are forwarded to target remote I/O stations.
Installation Requirements Insert CI810B 3BSE020520R1 into designated rack slot and lock fixing latch. Connect AF100 dedicated bus cable to front‑end port. Ensure back‑plane connector is fully engaged. Restore power supply, configure bus parameters and verify all remote I/O station data communication.
Usage Notes Adopt original AF100 matched bus cables. Follow specification limits for maximum bus length and station quantity. Hot‑plug under powered state is forbidden.
