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
