ABB CI865 3BSE040795R1 AC 800M Satt I/O Interface

Product Overview

The ABB CI865 (3BSE040795R1) is a specialized communication interface designed for the AC 800M controller family. Its primary function is to facilitate the connection between the controller and Satt I/O devices, acting as the Master in the network configuration. This module connects directly to the CEX-Bus (Communication Expansion Bus), allowing for efficient data exchange and system scaling. As an essential part of ABB's automation ecosystem, it ensures backward compatibility and modernization paths for existing Satt I/O installations.

Communication & Connectivity

Equipped with a standard BNC connector, the CI865 provides a stable physical interface for Satt I/O communications. The module is highly scalable, supporting up to 4 units on a single CEX-Bus. One of its most critical industrial features is Hot Swap capability, which empowers technicians to replace or maintain modules without powering down the system or causing process downtime. This ensures maximum system uptime in continuous manufacturing or power generation processes.

Physical Characteristics & Weight

The CI865 features a robust yet compact design, measuring 185 mm in height, 59 mm in width, and 127.5 mm in depth. Including its base, the unit has a maximum weight of 700 g (approx. 1.5 lbs). Its narrow 59mm profile is specifically designed to optimize cabinet space, allowing for high-density mounting on DIN rails. The IP20 protection class ensures safety against solid objects, while the hardware is built to operate reliably within an environment temperature range of +5 to +55 °C.

Technical Specifications

Environmental Durability

To withstand harsh industrial atmospheres, the CI865 is G3 compliant according to ISA 71.04 standards. This provides advanced protection against corrosive gases and humidity, significantly extending the module's lifespan in facilities like chemical plants or wastewater treatment centers. Electrically, the unit is efficient, with a typical power consumption of only 120 mA at 24 V DC, and it meets all modern environmental directives, including RoHS and WEEE compliance.

Technical FAQs

Q1: What is the maximum number of CI865 modules I can use per controller?
A1: You can configure up to 4 CI865 units on the CEX-Bus of a single AC 800M controller, allowing for extensive Satt I/O network expansion.

Q2: Does the CI865 require a specific base for installation?
A2: Yes, the module is typically mounted on a TP830 Baseplate or compatible unit to interface with the CEX-Bus and provide secure mechanical mounting.

Q3: Can I replace a faulty CI865 while the system is running?
A3: Yes, the CI865 supports Hot Swap functionality. However, always ensure that the application software and controller firmware version support online replacement before performing the task.
