ABB CI856K01 3BSE026055R1 AC 800M Communication Interface Module
Product Overview
The ABB CI856K01 is a communication interface module designed for integration of S100 I/O into the AC 800M control system via the CEX-Bus. It plays a crucial role in reusing existing ABB Master and Advant OCS installations by supporting connectivity to up to five S100 I/O racks. The CI856 module enables a seamless transition to modern control without major rewiring or hardware overhaul.
