Description

The ABB CI840A (3BSE041882R1) is a redundant PROFIBUS DP-V1 communication interface module engineered for integration within the ABB S800 I/O distributed control architecture. This module provides a high-availability master interface for connecting PROFIBUS field devices to AC 800M controllers via the ModuleBus. It facilitates deterministic cyclic and acyclic data exchange, supporting redundant controller configurations to eliminate single points of failure in process automation loops.

Designed for rail mounting on modular BasePlate configurations, the CI840A handles master-level communication tasks, parsing field instrumentation data and executing parameterization commands. Its hot-swap capability allows module replacement without interrupting the active process control loop, ensuring continuous operation in continuous-process industries.

Features

Redundant PROFIBUS DP-V1 master communication interface support for high-availability S800 I/O station architectures
Dual optical or electrical interface options for connection to redundant AC 800M controller CPU configurations
Supports up to 124 PROFIBUS slaves per master interface with baud rates up to 12 Mbps
Hot-pluggable module design enabling online replacement on MT810 or MT815 BaseUnits
Comprehensive diagnostic LED indicators for power, module status, communication health, and token ring status
Galvanic isolation between field communication circuits and internal ModuleBus electronics

Applications

Distributed control system (DCS) S800 I/O rack communication expansion
Redundant fieldbus master drop for continuous chemical and petrochemical processing
High-availability PROFIBUS DP network polling for smart instrumentation and actuators
Power generation turbine and auxiliary control loop interfacing
