ABB CI801‑EA (3BSE022366R2) — Product Overview
Brand: ABB
Series: S800 I/O (Fieldbus Communication Interface, Profibus DP‑V1)
Product Introduction
The CI801‑EA (catalog number 3BSE022366R2) is a Profibus DP‑V1 communication interface (FCI) for ABB’s S800 distributed I/O system. It supports hot configuration, HART pass‑through, module supervision (OSP), and isolated power for downstream modules. Acting as the gateway between a Profibus DP master (typically a PLC or DCS controller) and the S800 I/O rack, it simplifies integration by bridging field-level I/O modules with the control system.
