ABB TB810 3BSE008560R1 S800 I/O ModuleBus Optical Port Interface

Description

The TB810 3BSE008560R1 is a key component for distributed I/O in the System 800xA environment. Using Plastic Optical Fiber (POF) or Hard Clad Silica (HCS) fiber, it connects remote S800 I/O clusters to the main processor, ideal for environments with high electromagnetic interference or differing ground potentials. The module mounts easily on a DIN rail and connects directly to the ModuleBus, supporting both point-to-point and star-topology configurations with optical hubs, enabling a flexible and scalable I/O network.
