        Features:

        • Eight floating AC outputs serve discrete field switching.
        • 115/230 V AC circuits form the field-side range of the 456-4 output card.
        • The compact U-format card fits established SIMATIC S5 rack service.
        The order code combines eight AC outputs with the fuse and switching limits of this 456-4 configuration.

        It places a concentrated field interface beside legacy S5 control logic for contactors, valves, and indicator loads.

        Check the rack slot, front connector, fuse grouping, and cabinet clearance before energizing a replacement card.

        Availability is reviewed against the 456-4 AC output lifecycle and Apter Power sourcing records.

        • Switches eight AC field circuits in machine panels.
        • Drives contactors, valves, and indicator loads from S5-135U or S5-155U racks.
        • Restores an existing 456-4 output position without changing cabinet architecture.
        • The eight AC output circuits connect through the 456-4 front interface used by the S5 rack.
        • Fit the specified output fuse arrangement and verify the connector jumper before applying field power.
        • Series 3TJ contactors are limited to the 115 V AC operating case described for this module.
        • Floating AC channels keep the field load side separated across the eight output points.
        • The output protection scheme is intended to interrupt a fault at the individual circuit rather than bypassing the module fuse.
        • VDE insulation checks distinguish the output groups from the group-to-earth test path.
        • The output stage can drive resistive and inductive loads within the ventilated or non-ventilated use cases.
        • Its AC switching design supports contactor and lamp duties in established S5 machine panels.
        • UL and CSA switching-capacity ratings provide separate selection limits for the connected AC load.
        Description
        Siemens 6ES5456-4UB12 is the eight-point 456-4 AC output card for floating 115–230 V field circuits. Its compact U-format places a concentrated switching interface in established SIMATIC S5 cabinets.

        The outputs suit discrete commands for contactors, solenoids, valves, and pilot devices where the control program already uses the 456-4 position. The high-voltage field side keeps the original rack-based architecture intact. The eight outputs are individually protected by fast fuses, which helps isolate a failed AC branch during cabinet service.

        For a replacement, compare the front-connector conductors, output grouping, fuse arrangement, and AC load class before energizing. Cabinet clearance should accommodate the 40 mm × 255 mm × 195 mm module body. The documented module switching capacity reaches 1440 VA under UL and 2000 VA under CSA, so the applicable load approval must be checked.

        Technical notes
        Before replacing Siemens 6ES5456-4UB12, isolate the 115/230 V AC field supply and verify every front-connector conductor against the 456-4 slot drawing.
