        Features:

        • Sixteen isolated inputs monitor 115 to 230 V AC signals.
        • The 436-4 input stage accepts pulse trains up to 20 Hz.
        • The compact card retains the established S5 front-connector format.
        This UA12 configuration provides sixteen AC input points, 10 kohm typical input resistance, and a 0.55 kg card weight.

        It is used to acquire machine status and permissive contacts without changing the existing controller program.

        Check AC source level, connector pinout, input grouping, and cabinet clearance before the module is installed.

        Sourcing review covers the UA12 436-4 input variant and the required AC signal arrangement.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Brings sixteen AC field states into an S5 controller scan.
        • Supports machine status and permissive acquisition in 436-4 positions.
        • Offers a direct spare path when the original input order is retained.
        • The sixteen AC inputs are split into two isolated groups for the field circuits.
        • The documented VDE test levels separate group insulation from the group-to-earth check.
        • The input voltage class must be isolated before performing connector or terminal measurements.
        • The 436-4 function is fixed by the hardware module and does not require a field firmware update.
        • Input transitions are delivered to the S5 process image using the selected delay behavior.
        • A replacement should retain the same STEP 5 input addresses and rack slot definition.
        • The card exchanges its input states through the SIMATIC S5 backplane rather than an external bus port.
        • Two-wire BERO devices can share the AC input arrangement when their field current is compatible.
        • The front connector carries the grouped AC signals while the rack supplies the internal logic section.
        Description
        Siemens 6ES5436-4UA12 is a sixteen-point 436-4 input card for floating 115–230 V AC signals. Two isolated input groups allow high-density status acquisition from established field circuits.

        It brings machine contacts, permissives, and switch states into the S5 scan while preserving the existing input byte arrangement. The module is suited to legacy panels that need a direct 436-4 spare. The two input groups are designed around the 436-4 high-voltage AC sensing arrangement rather than a low-voltage DC interface.

        Before installation, identify the AC source, front-connector pins, group separation, and rack address. The card occupies about 40 mm × 255 mm × 195 mm and weighs approximately 0.55 kg. A 10 kohm input resistance and the documented 20 Hz rate should be considered when checking contact sources and response timing.

        Technical notes
        Before inserting Siemens 6ES5436-4UA12, isolate the 115/230 V AC inputs and verify the sixteen-point connector map against the installed 436-4 rack position.
