        Overview Manuals Specifications Shunt-Stick Planning Horizontal Installation Analog Input Matching

        Features:

        • Horizontal shunt-stick base: TU844 provides eight input-selection positions in a horizontal layout.
        • TY801 required separately: ABB states that the shunt stick is not included.
        • Redundant I/O scope: The approved module list covers AI845, AI880, AI880A, and DP840.

        TU844 combines redundant ModuleBus termination with per-channel voltage-or-current selection through TY801 shunt-stick positions.

        Because the shunt sticks are not included in the ABB product record, procurement must confirm their quantity and the intended input modes separately.

        Match TU844 and 3BSE021445R1 with the horizontal rail layout, I/O module, terminal schedule, mechanical keys, and accessories list.

        Availability is subject to Apter Power's current inventory and sourcing confirmation.
