ABB TU846 3BSE022460R1 is a redundant communication-interface Module Termination Unit for two CI840 or CI840A modules and redundant S800 I/O stations.
The MTU provides redundant PROFIBUS DP-V1, service, ModuleBus and optical connections while distributing the documented 24 VDC supply range to the communication-interface arrangement.
Because TU846 is not hot-swappable, isolate power before replacement and verify both CI840 or CI840A modules, PROFIBUS lines, station addressing, ModuleBus, optical expansion, DIN-rail orientation and controller configuration.

ABB TU846 3BSE022460R1 terminates two CI840 or CI840A communication interfaces for a redundant PROFIBUS DP-V1 and S800 I/O station.
ABB TU846 3BSE022460R1 supports line redundancy, communication-interface module redundancy and redundant I/O when the controller and station are engineered for those modes.
ABB TU846 3BSE022460R1 provides two PROFIBUS connectors, two service-tool connectors, two ModuleBus connectors and an optical ModuleBus interface.
ABB TU846 3BSE022460R1 is not documented for hot swap, so power must be isolated and the redundant station placed in the approved maintenance state before replacement.
ABB TU846 3BSE022460R1 uses a nominal 24 VDC supply with a documented 19.2 to 30 VDC operating range.
Commission ABB TU846 3BSE022460R1 by checking both CI840 or CI840A modules, PROFIBUS lines, ModuleBus and optical links, redundancy switching, diagnostics and controller I/O status.
Provide the full ABB TU846 3BSE022460R1 label, CI840 or CI840A revisions, station topology, wiring photos, quantity and destination.
Send the complete TU846 3BSE022460R1 catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before quotation.
