TB811 3BSE008568R1 | ABB | S800 Modulebus Optical Port

Product Overview

The ABB TB811 (3BSE008568R1) functions as a high-speed Modulebus Optical Port designed for the S800 I/O system and ABB Drives equipment. This module provides the critical fiber optic interface required to extend Modulebus communication between clusters. We supply this unit as 100% Brand New and Original, featuring full G2 Compliance. It enables deterministic data exchange over long distances, ensuring your DCS or Drive system maintains high-integrity control signals without the limitations of copper cabling.

Technical Specifications

The TB811 utilizes a specialized optical interface to bridge communication across industrial hardware:

Engineering Advantages

• Total Electromagnetic Immunity: The TB811 utilizes fiber optic technology to transmit Modulebus signals. This eliminates the risk of electromagnetic interference (EMI) and radio frequency interference (RFI), making it the ideal solution for environments with heavy motors, VFDs, and high-voltage switchgear.

• Extended Communication Reach: Fiber optic links surpass the distance limitations of standard copper Modulebus connections. The TB811 allows engineers to distribute I/O clusters and ABB Drives across larger plant areas while maintaining the microsecond-level synchronization required for high-performance automation.

• Seamless Drive Integration: This module interfaces directly with ABB Drives equipment. It facilitates a high-integrity link between the drive logic and the S800 I/O system, allowing for centralized monitoring and control of power conversion hardware.

• Ultra-Compact DIN-Rail Design: With a width of only 45 mm, the TB811 minimizes consumption of valuable rail space. The slim profile allows for easy integration into high-density communication cabinets without requiring significant panel redesign.

• G2 Compliant Reliability: As a G2 Compliant module, the TB811 meets stringent industrial standards for hardware durability and signal stability. This ensures a long service life in continuous-duty applications where communication downtime results in significant production losses.

FAQs

• Which communication interfaces require the TB811?

  You typically use the TB811 together with the CI810 or CI820 Fieldbus Communication Interfaces to extend the local Modulebus to remote I/O clusters via optical fiber.

• Does this module support both plastic and HCS fiber?

  The TB811 supports standard industrial fiber optic specifications for the S800 system. Always verify your specific fiber cable attenuation and connector type (typically versatile link or similar) before finalizing your network layout.

• Is this a refurbished or used unit?

  Absolutely not. We guarantee this TB811 is 100% Brand New original hardware. It arrives in the original ABB factory packaging with all security seals, the 3BSE008568R1 part number, and technical documentation intact.

• Does the TB811 require external 24V DC power?

  No. The module draws its operating power directly from the communication interface (CI810/CI820) or the drive logic it attaches to, simplifying the electrical installation process.
