ABB CI856K01 (3BSE026055R1) — Product Overview
Brand: ABB
Series: AC 800M Communication Interface (S100 I/O Interface Kit)
Product Introduction
The ABB CI856K01 (part number 3BSE026055R1) is a communication interface kit designed to connect ABB’s AC 800M controller series with the S100 I/O system. It contains both the CI856 communication interface and the TP856 baseplate. Mounted on a DIN rail, it bridges CEX-bus to S100 field I/O racks, facilitating distributed control with modular flexibility.
