ABB CI851 3BSE018116R1 Interface Module

Product Introduction

The ABB CI851 (3BSE018116R1) Interface Module is a key component within ABB’s AC 800M automation platform, specifically designed to integrate PROFIBUS-DP networks into the ABB Control System. This module serves as a PROFIBUS-DP Master, allowing the AC 800M controller to communicate with decentralized field devices such as I/O modules, drives, sensors, and actuators in real time.

Equipped with a DP-V1 interface, the CI851 ensures robust, high-speed, and deterministic communication with devices compliant with the PROFIBUS-DP standard. Its seamless plug-in design for the PM851/PM861/PM862/PM864 controllers makes it highly adaptable for process automation in demanding industrial environments.

Manufactured with industrial-grade components and ABB’s stringent quality standards, the CI851 ensures high availability and compatibility across multiple automation applications, from power generation and oil refining to advanced manufacturing systems.
