CI801 ABB S800 I/O Communication Interface | 3BSE022366R1

Product Overview

The ABB CI801 (3BSE022366R1) serves as the high-performance Fieldbus Communication Interface (FCI) for the S800 I/O system. It functions as a configurable bridge between parent controllers (such as Advant 800xA or PLCs) and distributed I/O modules via the PROFIBUS-DPV1 protocol. This module manages comprehensive signal processing, gathers supervision data, and executes OSP (Output Set as Predetermined) handling. We provide this unit as 100% Brand New original equipment, ensuring full support for advanced features like Hot Configuration InRun and HART pass-through.

Technical Specifications

The CI801 delivers high-speed data throughput and robust environmental resilience for demanding industrial architectures.

Engineering Advantages

• Optimized Signal Coordination: The CI801 gathers all supervision information from connected I/O modules and transmits it to the controller in a synchronized stream. This eliminates communication bottlenecks in high-density distributed I/O racks.

• HART Pass-Through Capability: It facilitates the digital exchange of instrument data between HART-enabled field devices and the asset management system. This allows engineers to perform remote calibration and diagnostics without additional hardware.

• Hot Configuration InRun (HCIR): The module supports system modifications while the process remains active. This feature allows you to add or reconfigure I/O modules without stopping the parent controller, maximizing plant uptime.

• Corrosion Resistance: With G3-level protection according to ISA-S71.04, the CI801 operates reliably in harsh industrial atmospheres containing corrosive gases, such as those found in chemical plants or wastewater facilities.

• Integrated Safety Handling: The CI801 manages OSP (Output Set as Predetermined) states. In the event of a communication loss, it automatically drives outputs to a user-defined safe state to protect downstream equipment.

FAQs

Q: Does the CI801 support all S800 I/O modules?

A: No. The standard system software in the CI801 does not support DI830, DI831, DI885, AI880, DI880, and DO880 modules. Always verify module compatibility before finalizing your rack design.

Q: What is included with the 3BSE022366R1 package?

A: Each brand new unit includes one (1) CI801 module, one (1) 3BSC840098R2 Power Supply Connector, and one (1) 3BSE008538R1 TB807 Modulebus Terminator.

Q: How do I handle a modulebus extension with the CI801?

A: The CI801 uses the included TB807 terminator to close the local Modulebus. If you require an extension to additional I/O clusters, you must integrate the appropriate Modulebus optical link or cable interface.

Q: Is this unit compatible with third-party PLCs?

A: Yes. Since the CI801 communicates via industry-standard PROFIBUS-DPV1, it can interface with any third-party PLC or controller that supports a Profibus DP Master.
