ABB CI840A Interface PROFIBUS DP-V1 – 3BSE041882R1

Description

The 3BSE041882R1 CI840A serves as a high-performance communication interface designed to manage data exchange between the S800 I/O station and a PROFIBUS DP-V1 master unit. This field communication interface handles cyclic data exchange alongside non-cyclic configuration, diagnostics, and parameter assignment tasks. Engineered for seamless deployment across industrial automation environments, it offers complete software compatibility with the ABB 800xA distributed control system and Compact Product Suite platforms. The unit acts as a crucial link for field devices, translating signals reliably while permitting the implementation of complete physical media redundancy. Operating the 3BSE041882R1 CI840A within demanding industrial plants guarantees precise, real-time control loop execution and continuous communication uptime across critical automation networks.

Features

• Provides standard field bus communication interface using the PROFIBUS DP-V1 protocol.
• Integrates directly into multiple generations of S800 I/O systems, including versions 4.1, 5.0, and 5.1.
• Facilitates full redundancy schemes for dual interface topologies when paired with specific modular terminal units.
• Features a lightweight, space-saving design optimizing DIN rail space inside standard marshalling panels.
• Operates with absolute zero battery requirements, reducing routine infrastructure upkeep costs.

Applications

• Distributed Control Systems (DCS) integration via PROFIBUS communication infrastructures.
• Redundant field I/O data aggregation for System 800xA production networks.
• Factory automation assembly interfaces using Compact Product Suite controller packages.
• High-availability process lines requiring redundant communication modules on matching terminal units.

Technical Specifications

Installation Guidelines

• DIN Rail Assembly: Fit the interface module firmly onto its designated slot on the terminal base unit. Ensure the rear grounding contacts press cleanly against the DIN rail.
• Redundancy Configuration: To implement a redundant communication interface, two CI840A modules must be ordered and paired with either one TU847 or one TU846 terminal unit.
• Network Segment Isolation: Route the PROFIBUS DB9 network cable away from high-voltage motor starters and power lines to reduce EMI/RFI noise injection.
• Module Retention: Verify the module locking latches engage properly after insertion into the base unit to withstand industrial vibration and shock.

Compliance and Certifications

• RoHS Directive: Manufactured in accordance with the regulatory standards outlined in EU Directive 2011/65/EU.
• WEEE Category: Classified under Category 5: Small Equipment (No External Dimension More Than 50 cm).
