3BSE018144R1 ABB CI857 Master Communication Module INSUM

Product Overview

The ABB CI857 (3BSE018144R1) is a dedicated communication interface module designed for the AC 800M controller series. Operating as an INSUM Master, the CI857 facilitates high-speed integration between the control system and intelligent motor control centers. Despite its lightweight and compact design (approx. 0.3 kg), this module provides a powerful 10 Mbps bandwidth for real-time monitoring of up to 128 devices, ensuring high-density data acquisition without adding significant mechanical load to the CEX-bus rail.

Technical Configuration

Mechanical & Network Features

• Lightweight Architecture: At only 0.3 kg (approx. 0.66 lbs), the module is optimized for high-density rail mounting.
• Protocol Support: Native INSUM protocol integration for ABB intelligent motor control units.
• Device Capacity: Supports up to 128 INSUM devices per single CI857 module.
• Communication Speed: 10 Mbps fixed transmission rate for responsive data throughput.
• Compliance: Fully CE-marked, RoHS, and WEEE certified.

Installation & Maintenance Guide

Engineering Guidelines

CEX-Bus Loading: Due to its minimal weight of 0.3 kg, the CI857 places negligible mechanical stress on the AC 800M CEX-bus. However, always ensure that the total weight and power consumption of all combined modules do not exceed the mechanical specification of the mounting rail and the electrical capacity of the bus.

Shipping & Handling: For international logistics, the compact dimensions and light weight of this unit contribute to lower shipping costs. Ensure the unit is shipped in anti-static packaging, as the lightweight plastic housing (IP20) requires standard protection against impact and ESD during transit.

Engineering Advantages

The CI857 3BSE018144R1 provides a centralized gateway for motor management, reducing the need for extensive hard-wiring. Its low-mass design makes it ideal for seismic-sensitive installations or mobile offshore platforms where every kilogram of cabinet weight is scrutinized. By utilizing the INSUM protocol, engineers gain access to advanced diagnostic data directly within the AC 800M environment, lowering the Total Cost of Ownership through streamlined commissioning.

Technical FAQs

Q1: What is the exact weight of the CI857 module?
A1: The net weight of the module is approximately 0.3 kg. For shipping purposes, including the original ABB box and protective materials, we typically calculate a gross weight of 0.5 kg.

Q2: Does the weight include the baseplate?
A2: No, the 0.3 kg weight refers to the CI857 plug-in module itself. The AC 800M baseplates are separate mechanical components.

Q3: Is the module robust despite its light weight?
A3: Yes, while light, the housing is engineered to meet industrial vibration standards and is IP20 rated for protection against solid objects when mounted correctly in a cabinet.
