CI840A-1 3BSE041883R1 ABB Communication Module for S800 I/O Systems

Description

The ABB CI840A-1 is a robust and compact communication module engineered for industrial automation systems that require reliable and scalable I/O integration. It is part of the S800 I/O family, which is widely used in System 800xA environments for process control, power generation, and manufacturing. This module supports thePROFIBUS DP-V1protocol, enabling fast and deterministic communication with field devices. It is designed for redundant applications, allowing two CI840A modules to operate in parallel withTU846orTU847base units. Moreover, the CI840A-1 supportshot swapping, meaning it can be replaced without shutting down the system, minimizing downtime and simplifying maintenance. In addition, its compact form factor and low power consumption make it ideal for installations with space and energy constraints. The CI840A-1 is built to withstand harsh industrial environments and ensures long-term reliability in mission-critical applications.
