ABB CI820V1 Fieldbus Communication Interface Module

Technical Specifications Model: CI820V1 Bus Interface: S800 ModuleBus dedicated field‑bus interface Communication Medium: Shielded twisted‑pair cable Power Supply: 24 V DC supplied by rack backplane Operating Temperature: ‑20 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: AC800M rack plug‑in module Protection Class: IP20 Certifications: CE

Functional Features Realizes high‑speed data interaction between AC800M controller and S800 remote‑I/O stations. Automatically downloads configuration parameters for each S800 I/O module on remote‑stations. Collects running‑status and fault‑diagnosis information of remote‑I/O modules and uploads to main controller. Supports hot‑swap operation of S800 remote‑I/O modules under system running condition. Front‑panel LED indicators show module power‑on, running, ModuleBus communication and fault‑alarm status. Built‑in bus‑signal galvanic‑isolation circuit restrains field‑bus ground‑loop interference. Supports ModuleBus communication‑redundancy configuration for high‑availability control‑system.

Application Scenarios AC800M control‑system S800 remote‑I/O expansion cabinet spare‑part‑replacement. Chemical, power‑plant, pulp‑and‑paper‑industry distributed remote‑signal‑collection automation projects.

Installation Requirements Insert CI820V1 module into designated slot of AC800M rack and lock spring‑clip buckle. Connect S800 ModuleBus shielded twisted‑pair field‑bus cable to front‑side bus‑signal terminals. Complete cabinet protective‑earthing complying with AC800M system grounding specifications. Lay ModuleBus field‑bus cables separately from high‑power power‑cables. Reserve ventilation‑heat‑dissipation space around module slot.
