The ABB TB811 (Order Code: 3BSE008568R1) is a Modulebus Optical Port module designed for industrial automation systems. It serves as a critical interface within the ABB S800 I/O system, enabling the conversion of electrical signals to optical signals for transmission over fiber optic cables. This module is essential for extending communication distances and providing robust electrical isolation between control modules and I/O clusters.

Features

  • Optical Modulebus interface for S800 I/O systems.
  • Designed for integration with CI810 and CI820 communication interfaces.
  • Supports high-speed optical communication for distributed control architectures.
  • Provides 2.5 kV AC electrical isolation.
  • Continuous autodiagnostics for system start-up and operational monitoring.

Applications

  • Power & Energy: Generator set monitoring and substation automation.
  • Oil & Gas: Distributed control systems for refineries and offshore platforms.
  • Metals & Mining: Blast furnace control and large-scale production line management.
  • Pulp & Paper / Chemical: Drive system control and batch processing automation.
