ABB CI857 3BSE018144R1 System 800xA INSUM Communication Interface

Product Overview

The ABB CI857 (3BSE018144R1) serves as the dedicated Master interface for ABB’s INSUM (Integrated System for User-optimized Motor control) within the System 800xA architecture. This module enables AC 800M controllers to integrate seamlessly with intelligent Motor Control Centers (MCC), providing real-time supervision and control over motor starters and switchgear. We supply this unit as 100% brand new original equipment, ensuring full technical compliance with G3 harsh environment standards for mission-critical industrial applications.

Technical Specifications

The CI857 utilizes a high-speed CEX-Bus connection to provide deterministic data throughput between the controller and the INSUM network.

Engineering Advantages

• Seamless Safety Integration: The CI857 works directly with High Integrity (HI) Controllers. This allows engineers to implement complex motor control strategies within safety-instrumented systems without compromising SIL ratings.

• Corrosion Resistance in Harsh Zones: Standard G3 conformal coating protects the internal circuitry against atmospheric pollutants. This solves the common industrial pain point of hardware failure in wastewater treatment or chemical processing plants where corrosive gases often degrade standard electronics.

• Efficient System Maintenance: The module supports Hot Swap functionality. Technicians replace units while the controller remains energized, significantly reducing Mean Time to Repair (MTTR) and preventing unnecessary process shutdowns.

• Compact CEX-Bus Footprint: With a narrow width of only 59 mm, the CI857 maximizes rail space. This compact design allows for the installation of up to 6 units on a single CEX-bus, facilitating large-scale motor networking in restricted cabinet environments.

FAQs

• Can I use the CI857 with non-INSUM Ethernet protocols?

  No. The CI857 specifically runs ABB's proprietary INSUM protocol to communicate with intelligent motor starters. For standard Ethernet or Modbus TCP applications, you must select the appropriate CI-series module (e.g., CI867).

• Does the CI857 support redundancy?

  This specific module does not support line or module redundancy. For applications requiring high-availability communication, ensure your network topology accounts for the single-master nature of the CI857.

• Is this a genuine, factory-sealed ABB part?

  Yes. We guarantee this CI857 3BSE018144R1 is 100% Brand New and arrives in original ABB packaging. We do not sell refurbished or "new-surplus" units with compromised service lives.

• What cable type does the RJ-45 port require?

  The unit utilizes standard 8-pin RJ-45 connectors. For optimal performance and noise immunity, especially in G3 environments, use high-quality shielded twisted pair (STP) cables compliant with ABB's INSUM installation guidelines.
