CI801 3BSE022366R1 | ABB | S800L PROFIBUS Fieldbus Communication Interface

Product Overview

The ABB CI801 (3BSE022366R1) functions as the primary PROFIBUS Fieldbus Communication Interface (FCI) for the S800L I/O system. This module manages the data exchange between a PROFIBUS DP master and a cluster of S800L I/O modules via the internal Modulebus. We supply this unit as 100% brand new original equipment, ensuring seamless protocol conversion and high-speed signal processing for your distributed control network.

Technical Specifications

The CI801 utilizes a compact mechanical design and includes essential termination hardware to ensure immediate system stability.

Engineering Advantages

• Optimized S800L Integration: The CI801 provides a cost-effective, high-density interface specifically for S800L modules. Its narrow 85.6 mm width solves the challenge of overcrowded control cabinets by maximizing DIN-rail real estate.

• Turnkey Connectivity Kit: Each CI801 arrives with a TB807 Modulebus Terminator and a dedicated power supply connector. This ensures you have the necessary components to terminate the I/O bus correctly, preventing signal reflections and communication errors from day one.

• Simplified Fieldbus Architecture: The module acts as a transparent gateway, mapping I/O data to PROFIBUS DP registers. This removes the complexity of individual module addressing on the fieldbus, as the CI801 handles all local Modulebus traffic autonomously.

• Robust Zero-Battery Design: The interface requires no batteries for operation or memory retention. This maintenance-free architecture reduces long-term ownership costs and eliminates the risk of data loss during extended power outages in remote locations.

FAQs

• Which I/O modules are incompatible with the CI801?

  The basic system software loaded in the CI801 does not support the following modules: DI825, DI830, DI831, DI885, AI880, DI880, and DO880. If your system requires these specific modules, please consult with us for alternative FCI options.

• Does this unit include the Modulebus terminator?

  Yes. Each CI801 package includes one TB807 Modulebus Terminator (3BSE008538R1). You must install this at the end of your I/O cluster to ensure stable communication.

• What is the condition of this hardware?

  We guarantee this is a 100% Brand New original ABB part. It arrives in its original factory-sealed packaging with full technical documentation and has never been used or refurbished.

• How many I/O modules can the CI801 manage?

  The CI801 typically manages a cluster of up to 12 S800L I/O modules on a single local Modulebus, depending on the power consumption and total signal count of the connected units.
