Description

The ABB TB845 (Product ID: 3BSE021437R1) is a redundant ModuleBus cable adaptor designed for the S800 I/O system within the ABB Ability System 800xA platform. The device is used in combination with the TB846 adaptor and two TK801V0xx cables to extend the electrical ModuleBus, enabling S800 I/O modules operating on the same electrical ModuleBus to be mounted across separate DIN rails.

Features

  • Enables extension of the electrical ModuleBus across multiple DIN rails
  • Designed for redundant ModuleBus configurations in S800 I/O stations
  • Works in combination with TB846 adaptors and TK801V0xx extension cables
  • Compact form factor for standard DIN rail mounting environments

Applications

  • Distributed control system (DCS) extension in ABB Ability System 800xA installations
  • Cabinet expansion for S800 I/O cluster arrangements across multiple DIN rails
  • Redundant ModuleBus communication links in process automation architectures
