Basic Product Identification
Model & Article Number: Model CI840A, corresponding article number 3BSE041882R1.
Product Category: Fieldbus Communication Interface (FCI) module, part of ABB’s Compact Product
Suite and S800 I/O system, serving as a communication bridge between controllers/PLCs and field
devices via PROFIBUS.
Core Purpose: Enables data transmission between parent controllers/PLCs and distributed I/O
modules, supporting redundant and non-redundant industrial control system configurations.
Core Functional Characteristics
Protocol & Role: Complies with PROFIBUS DP-V1 protocol, functioning as a slave device in the
fieldbus network.
Redundancy Capabilities: Supports line redundancy and module redundancy, designed for high-
availability redundant applications to ensure uninterrupted communication.
Key Functions:
Provides supervisory functions for the I/O ModuleBus, isolating power supply to I/O modules for
stable operation.
Handles OSP (Open Standard Profile) tasks and I/O module configuration, supports Hot Configuration
In Run (configuration adjustments during system operation) and Hot Swap (hot-swappable for
maintenance without downtime).
Features HART pass-through to transmit HART communication signals between field devices and
controllers.
Termination Unit Compatibility: Matches with TU846 termination units (for redundant I/O) and TU847
termination units (for non-redundant I/O) for proper wiring and signal termination.
Additional Design: Input power is fused for overcurrent protection; compatible with HI Controllers for
extended application scenarios.
Technical Specifications
Power Consumption: Typical 190 mA at 24 V DC.
Mechanical Dimensions: Width 54 mm (2.13 in.), height 119 mm (4.69 in.), depth 96 mm (3.78 in.);
weight 0.2 kg (0.44 lbs.), consistent with S800 I/O series module size standards.
Environmental Adaptability
Temperature Range: Operating 0–+55 °C (+32–+131 °F, approvals apply to +5–+55 °C); storage -40–
+70 °C (-40–+158 °F).
Humidity & Pollution: 5–95% relative humidity (non-condensing); pollution degree 2 (per IEC 60664-
1).
Special Adaptability: Corrosion protection compliant with ISA-S71.04: G3; maximum ambient
temperature 55 °C (131 °F) for vertical mounting, 40 °C (104 °F) for other mounting orientations.
Protection Class: IP20 (per EN60529/IEC 529), suitable for installation in control cabinets.
