CI801 3BSE022366R1 ABB Bailey

Product Dimensions：

The CI801 is a modular, DIN-rail mounted fieldbus interface that manages communication between the master control system (such as an AC 800M controller) and up to 24 S800 I/O modules. It acts as a gateway, translating the internal module bus protocols into standard PROFIBUS DP-V1 messages and vice versa. The unit is designed with intelligence, meaning it handles the configuration, scanning, and diagnostics of its attached I/O modules independently, which significantly offloads the main controller. The "3BSE022366R1" designation refers to the precise ABB ordering and manufacturing part code, ensuring compatibility within the System 800xA architecture.

Product Parameters

• Product Type: PROFIBUS DP-V1 Fieldbus Communication Interface

• Model Designation: CI801

• Product ID: 3BSE022366R1

• Protocol Supported: PROFIBUS DP-V1 (enables advanced acyclic communication for parameters and diagnostics)

• Maximum I/O Modules: Connects up to 24 S800 I/O modules per cluster (using I/O cluster modems)

• Baud Rate: Auto-detecting transmission speed up to $12 \text{ Mbps}$

• Power Supply: $24 \text{ VDC}$ nominal input voltage

• Power Consumption: Typically $100 \text{ mA}$ at $24 \text{ V}$

• Isolation: Galvanic isolation between the PROFIBUS network and internal circuitry

• Mounting: Standard $35 \text{ mm}$ DIN rail mounting on a TU810, TU812, or TU814 Terminal Base

• Protection Class: IP20 rating, requiring placement within a secure control enclosure

Product Advantages

A major advantage of the CI801 is its support for PROFIBUS DP-V1 Acyclic Data, which allows operators to configure smart field instruments and retrieve complex diagnostic information without interrupting the cyclic process data transfer. The Hot-Swapping (HCIR - Hot Configuration in Run) capability is another key benefit; it permits the replacement of faulty I/O modules or configuration changes while the system remains fully operational, drastically minimizing downtime.

The High Scalability of the S800 system means you can attach a large variety of analog and digital I/O modules to a single CI801 interface, creating a compact yet dense field solution. Furthermore, the module features Comprehensive Onboard LED Diagnostics for power, network status, and module faults, allowing maintenance teams to troubleshoot network issues quickly on the factory floor.

Important Considerations and Precautions

When configuring the CI801, the PROFIBUS Station Address must be correctly set via the rotary switches on the side of the unit before power-up, as changing the address while the unit is active will not take effect until a power cycle occurs. Termination Resistors are mandatory at both physical ends of the PROFIBUS network segment; failing to enable termination or enabling it in the middle of a line will cause severe signal reflection and intermittent communication drops.

Because the module is rated at IP20, it is highly sensitive to Conductive Dust and Moisture, meaning it must be installed inside a cabinet with climate control if operating in harsh industrial zones. When wiring the $24 \text{ VDC}$ power supply, always use a Filtered SELV or PELV Power Source to protect the internal processing units from voltage spikes. Finally, ensure that the total Current Consumption of the attached I/O modules does not exceed the limits of the terminal base to prevent thermal overload.

Product Applications

The ABB CI801 is heavily utilized in distributed control configurations across the process and manufacturing sectors.

• Oil and Gas Facilities: Transmitting signals from remote wellheads and tank farms back to a centralized AC 800M controller.

• Chemical Plants: Integrating discrete valves, temperature transmitters, and safety loops into the main control network via decentralized S800 clusters.

• Power Generation: Monitoring auxiliary system parameters, such as cooling water loops and fuel delivery status, where high speed and data integrity are required.

• Water and Wastewater Treatment: Managing dispersed pumping stations, aeration basins, and filtration units over long-distance fieldbus lines.

• Pulp and Paper Mills: Controlling complex multi-stage rollers and chemical dosing feeds along the production line.
