ABB CI857K01 / CI857 (3BSE018144R1) — Product Overview

Brand: ABB
Series: AC 800M / System 800xA — INSUM Ethernet Communication Interface


Product Introduction

The CI857K01, also known simply as CI857 (ABB part number 3BSE018144R1), is an Ethernet-based INSUM fieldbus interface module. Designed for ABB’s AC 800M controllers, it enables seamless integration with the INSUM Ethernet network, providing reliable, long-distance data exchange with precise time-stamped control loops. The interface is hot-swappable and powered through the controller’s backplane—no separate power needed.

Product Applications

  • Process automation, including long-distance signal distribution and motor synchronization within ABB’s 800xA systems

  • Ideal for environments needing time-distributed control loops, accurate time-stamping, and extended Ethernet ranges

  • Bridges INSUM field communication with devices like MCUs, gateways, and redundant network nodes

  • Supports high-availability systems where fieldbus uptime and live maintenance are required (hot-swap capable)


Product Advantages

  • Seamless INSUM integration: High-capacity master interface for control loops up to six CI857 modules and 128 MCUs per CI857

  • Hot-swap ready: Replace interface units under power without stopping processes

  • Field-hardened design: Industrial IP20 rating with robust corrosion protection and extended temperature range

  • Powered via backplane: No external power needed—draws clean power through CEX-Bus

  • ABB-certified quality: Designed for industrial Ethernet environments and ABB’s modular architecture
