The ABB TB840 3BSE021456R1 is a Modulebus Cluster Modem for use with the ABB S800 I/O system , 

providing a fiber‑optic interface (Optical Modulebus) as well as electrical Modulebus connectivity. It 

enables a modular I/O architecture in which I/O modules are organized in clusters, facilitating communication 

with controllers over long distances or across distributed installations — especially in applications that 

require expansion, flexible I/O cluster distribution, or remote I/O stations.
