Technical Specifications Part Number: 3BSE058590R1 Model: CI861K01 Communication Protocol: FOUNDATION Fieldbus H1 Interface: FOUNDATION Fieldbus H1 bus terminal interface Power Supply: Supplied by rack CEX‑Bus backplane Operating Temperature: ‑20 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: AC800M rack plug‑in module, matched with TP861 baseplate Protection Class: IP20 Certifications: CE, ATEX intrinsic‑safety relevant certification support
Functional Features Provides independent FOUNDATION Fieldbus H1 bus physical channel for AC800M controller. Realizes cyclic process‑data exchange and acyclic parameter access for H1 field‑bus instruments. Supports H1 bus‑segment field‑instrument power supply distribution function. Front‑panel LED indicators display module power‑on, running, H1 bus communication and fault‑alarm status. Supports module hot‑swap, field‑bus wiring remains on TP861 baseplate during replacement. Complete H1 bus‑segment short‑circuit, bus‑noise and equipment‑offline comprehensive diagnosis function. Supports redundant configuration for high‑reliability process‑automation‑system projects.
Installation Requirements Fix TP861 baseplate to designated slot of AC800M rack, insert CI861K01 module and lock spring‑clip buckle. Connect FOUNDATION Fieldbus H1 shielded field‑bus cable to screw‑type terminals of TP861 baseplate. Install terminal matching resistance at two ends of H1 bus‑segment complying with FF‑H1 specification. Complete cabinet protective earthing complying with AC800M system grounding specifications. Lay H1 field‑bus cables separately from high‑power power cables. Reserve heat‑dissipation ventilation‑space around module slot. Ambient operating temperature must stay within ‑20 ℃ ~ +60 ℃ without condensation.
