Functional Description
The ABB TU846 3BSE022460R1 connects power supply, dual ModuleBuses, and two CI840/CI840A units. Engineers configure station addresses using dual rotary switches ranging from 0 to 99. The unit supports ModuleBus Optical Port TB842 via TB846, enhancing flexibility in system design. Mechanical keying prevents incorrect module insertion, while a DIN rail latching device ensures secure grounding and locking.
Design and Build
The ABB TU846 3BSE022460R1 measures 12.7x5.1x20.3cm and weighs 0.3kg, making it compact yet durable. It offers 36 mechanical keying options for configuration, ensuring compatibility with multiple module types. The maximum ModuleBus length from the unit to the terminator is 2.5 meters. Engineers must allow space on the left for removal and disconnect power before replacement to ensure safe maintenance.
Applications and Compatibility
The ABB TU846 3BSE022460R1 Module Termination Unit integrates seamlessly with redundant I/O systems in S800 I/O architecture. Engineers deploy it in power plants, manufacturing facilities, and process industries requiring high availability. For single I/O modules, ABB recommends the TU847.
