Product Features
ABB TU848 3BSE042558R1 supports dual power supply input, ensuring stable and redundant power supply for the device.
ABB TU848 3BSE042558R1 is equipped with a rotary switch for cluster address settings from 1 to 7.
ABB TU848 3BSE042558R1 has two mechanical keys for configuring the MTU to match the correct module type, with each key having 6 positions, providing a total of 36 different configurations. The configuration can be changed using a screwdriver, preventing the insertion of the wrong module type.
ABB TU848 3BSE042558R1 features a redundant ModuleBus to enhance system reliability.
ABB TU848 3BSE042558R1 includes a DIN rail locking device for locking and grounding, supporting DIN rail installation, which can be mounted vertically or horizontally.
Product Using Principle
TU848 3BSE042558R1 as a passive unit, supplies power to the TB840/TB840A modems via dual power connections, with dual electrical ModuleBus providing redundant backup for data transmission.
A rotary switch is used to set the cluster address, ensuring proper identification and communication of the device within the cluster.
Different configurations of mechanical keys can accommodate different types of modules, preventing incorrect installation.
TU848 3BSE042558R1 Connected TB840/TB840A to redundant I/O with an external power supply for signal transmission and isolation. Furthermore, it has a locking mechanism on the DIN rail to strongly fix and ground it, guaranteeing equipment reliability and safety.
