ABB CI857 3BSE018144R1 | AC 800M INSUM Communication Interface

Product Overview

The ABB CI857 is a specialized communication interface module tailored for the AC 800M controller. As an INSUM protocol master, it acts as the vital bridge between the control system and intelligent motor control devices. By facilitating the exchange of critical diagnostic and operational data, the CI857 allows for advanced motor management strategies within the ABB Ability™ System 800xA, ensuring optimal performance and protection of high-value industrial motors.

Technical Configuration

This interface module is engineered for high-density motor control integration:

• Protocol Support: Native INSUM protocol implementation for seamless communication with ABB motor control centers.
• Network Capacity: Capable of managing up to 128 downstream INSUM devices per single CI857 module.
• Performance: Fixed transmission speed of 10 Mbps ensures rapid update rates for motor protection and status data.

Technical Specifications

Installation & Maintenance

Physical Deployment: The CI857 mounts directly onto the AC 800M CPU backplane or a dedicated communication expansion base. While the unit is lightweight at 0.55 kg, it must be installed in an environment that maintains the IP20 integrity and avoids condensation, especially during storage where temperatures can range down to -40°C.

System Limits: This module does not support line or module redundancy. For critical motor control loops, system designers should consider distributing INSUM devices across multiple CI857 modules to minimize the impact of a single point of failure.

Engineering Advantages

• Optimized Diagnostics: Provides access to deep-level motor parameters that standard I/O modules cannot capture.
• Standardized Integration: Fully CE and RoHS certified, ensuring adherence to global industrial safety and environmental standards.
• Scalable Architecture: The ability to connect 128 devices per master allows for highly efficient use of rack space in large motor control centers.

Technical FAQs

Q1: Does the CI857 support redundancy?
A1: No, the CI857 3BSE018144R1 is designed for non-redundant configurations and does not offer line or module redundancy options.

Q2: What is the maximum distance for the INSUM network?
A2: The distance depends on the physical layer and cabling used (e.g., LonWorks). Refer to the ABB INSUM System documentation for specific cabling guidelines.

Q3: Can the CI857 be used with AC 800F controllers?
A3: No, this module is specifically designed for the AC 800M series of controllers within the 800xA ecosystem.
