ABB TB846 S800 I/O System TB846 Dual Modulebus Inlet Module

The TB846 is a redundant ModuleBus Cable Adaptor used in ABB's Ability™ System 800xA® I/O system, working alongside the TB845 [ABB Ability System 800xA®]. Here's a breakdown of its functionality:

• Purpose: Similar to the TB845, the TB846 facilitates extending the reach of the ModuleBus. This bus transmits data between I/O modules (controllers acquiring data from field devices) and the main controller in the System 800xA.

• Redundancy Partner: The TB846 works in conjunction with the TB845 to create a redundant connection. This means if the primary connection between modules fails, the TB846 enables communication through a secondary path, ensuring continued operation.

• Optical Extension (Optional): The TB846 can be used with the TB842 to provide an optical extension of the ModuleBus. This is helpful for longer distances or areas where electrical interference might be a concern.

• Usage: Here's a typical setup involving the TB846:

1. The TB845 is connected to the primary ModuleBus.

2. The TB846 is connected to the secondary ModuleBus.

3. Two TK801V0xx terminator modules are used, one at each end of the extended ModuleBus created by the TB845 and TB846 combination
