Product Introduction
The ABB CI853 (3BSE018124R1) Interface Module is an advanced communication interface designed for integration between AC 800M controllers and the S100 I/O system. This module allows legacy S100 I/O units—widely used in ABB’s traditional control environments—to connect seamlessly with modern control platforms like the AC 800M, thereby extending the lifespan and functionality of existing hardware.
Installed within the ABB 800xA system architecture, the CI853 module provides a smooth migration path for facilities that want to retain their installed base of S100 I/O while upgrading to the flexibility and performance of the AC 800M family. It uses the ModuleBus interface to communicate with the controller and connects to the S100 I/O via a cable to the S100 I/O bus.
The CI853 thus bridges generational technology gaps, ensuring plant operators benefit from both cost-effective upgrades and advanced functionality, making it ideal for brownfield automation projects and modernization strategies.

Frequently Asked Questions (FAQ)
-
What is the main purpose of the ABB CI853?
It connects S100 I/O systems to the AC 800M controller family via ModuleBus. -
Can CI853 be used in a fully new installation?
It is primarily designed for retrofit or migration projects where S100 I/O already exists. -
Is CI853 compatible with all AC 800M CPUs?
Yes, it supports PM851 through PM865 controller modules. -
What is the maximum communication distance to the S100 I/O?
Up to 15 meters (50 feet) using a shielded cable. -
Does CI853 support redundant configurations?
While the module itself does not offer redundancy, redundancy can be architected at the system level. -
Can CI853 interface with S800 I/O?
No, CI853 is specifically for S100 I/O. Use CI854 or CI853 with ModuleBus for S800 I/O. -
Does the module require external power?
No, it receives power through the base unit (e.g., TU853). -
What type of installation is required?
It is mounted on a DIN-rail compatible base unit and connected via cables to S100 I/O. -
Is any software required for configuration?
Yes, configuration is done via ABB’s Control Builder software in the 800xA system environment. -
What is the product’s typical operating lifespan?
Over 10–15 years, depending on operational conditions and maintenance.
