        Overview Manuals Applications Connectivity Configuration & Programming Diagnostics & Protection

        Features:

        • Sixteen floating outputs expand AC command density in one S5 position.
        • Its field side accepts 115/230 V AC for the sixteen-point output group.
        • Its 456-4 compact construction supports established cabinet layouts.
        This configuration provides sixteen AC output points with four-point fuse grouping and the specified 39 W operating dissipation.

        It is suited to grouped actuator commands where the original SIMATIC S5 address map must remain intact.

        Confirm the connector arrangement, load class, and available clearance before inserting the module into service.

        Availability depends on the sixteen-point AC variant remaining traceable in Apter Power procurement checks.

        • Controls a multi-actuator machine section from one S5 rack position.
        • Provides grouped AC commands for starters, solenoids, and interlocked devices.
        • Maintains the original 456-4 channel density during spare-module replacement.
        • The sixteen AC outputs are arranged as two isolated groups of eight for field-side distribution.
        • Each fuse group serves four outputs, giving the rack wiring a defined load-protection boundary.
        • The front connector carries the field circuits while the backplane supplies the module logic section.
        • Choose the rack address and fuse grouping from the existing S5 output map before wiring the card.
        • Contactor selection follows the documented 115 V AC or 230 V AC size ranges for each output group.
        • The front enable jumper must match the project wiring state before the controller is placed in RUN.
        • The module separates overload protection by fuse group so a fault does not remove every output point.
        • Inrush behavior should be checked against the connected lamp or contactor bank during commissioning.
        • The AC output design provides a defined residual-current limit when a channel is in the logic-zero state.
        Description
        Siemens 6ES5456-4UA12 combines sixteen floating 115–230 V AC outputs with the dense 456-4 SIMATIC S5 format. It is intended for grouped actuator interfaces that need more points in one rack position.

        The card can coordinate starters, relays, lamps, and other discrete AC loads while retaining the byte and channel organization of the existing S5 application. Its four-output protection grouping supports orderly field wiring. Four-output protection groups make the UA12 suitable for organized actuator banks where each branch can be inspected independently.

        Selection should follow the installed connector, fuse group, inrush behavior, and available enclosure space. The 40 mm × 255 mm × 195 mm form must be checked against the cabinet and adjacent cards. The 88–264 V AC supply range should be reconciled with the site distribution and the load inrush profile before energizing.

        Technical notes
        For Siemens 6ES5456-4UA12, confirm the sixteen-channel AC load grouping and the original S5 output address map before reconnecting the front terminal wiring.
