        Overview Manuals AC Input AS-i Power Aux Output Terminals

        Features:

        • Selectable 115/230 V AC input feeds two controlled DC output paths.
        • The 30 V DC, 4 A path supplies AS-i while preserving data decoupling.
        • A separate 24 V DC, 5 A output feeds auxiliary loads.
        Siemens 3RX9306-1AA00 combines AS-i network power and auxiliary device power in one IP20 unit.

        The two output paths of 3RX9306-1AA00 carry different voltages and circuit roles.

        Input selection, branch protection, and terminal wiring determine safe startup of 3RX9306-1AA00.

        Verify the complete Siemens 3RX9306-1AA00 AS-Interface Combined Power Supply article number and documented interface before matching the installed unit.
        Siemens 3RX9306-1AA00 AS-Interface Combined Power Supply Manuals,Datasheets,Link 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.

        Selectable Mains Connection

        • Voltage selector: The unit is set for the 115 V or 230 V input range before energization.
        • Range check: Measured mains voltage must remain inside the selected documented range.
        • Frequency: The source remains between 47 and 63 Hz.
        • Protection: The mains branch uses the specified breaker characteristic and rating.

        Data-Decoupled 30 V Path

        • Network output: The 30 V DC output feeds the AS-Interface cable at up to 4 A.
        • Data decoupling: Communication signals remain superimposed on the powered AS-i conductor pair.
        • Current limit: The output protection acts when the network load reaches the documented boundary.
        • Fault check: Network cable polarity, load current, and short circuits are checked together.

        Separate 24 V Load Path

        • Auxiliary voltage: The 24 V DC output supplies loads that do not use the AS-i data path.
        • Rated current: Connected auxiliary loads share the documented 5 A output capacity.
        • Wiring separation: The auxiliary pair is not substituted for the AS-i profile conductors.
        • Load diagnosis: Voltage, current, polarity, and field-cable continuity are tested at the output.

        Conductor and Cooling Boundaries

        • Spring terminals: Input and output conductors use the documented 0.8 to 2.5 mm² range.
        • Polarity: Each DC path follows its marked positive and return terminals.
        • IP20 enclosure: The open-equipment rating requires installation inside a suitable enclosure.
        • Heat path: Cabinet airflow keeps the supply within its 55 °C operating maximum.
        Description
        Siemens 3RX9306-1AA00 is an IP20 AS-Interface combined power supply that converts a selectable 115 or 230 V AC input into two controlled DC paths. The AS-i path delivers 30 V DC with data decoupling, while the auxiliary path supplies 24 V DC without carrying AS-i communication.

        The 30 V output of 3RX9306-1AA00 is rated at 4 A and feeds the AS-Interface profile cable. Its separate 24 V output is rated at 5 A for auxiliary loads, so the two outputs must be wired to their documented conductors instead of being treated as one interchangeable supply.

        Spring-loaded terminals on 3RX9306-1AA00 accept the documented conductor range, while short-circuit protection and current limiting act on the DC outputs. The mains selector, protective device, and AC range must be checked before energizing the unit.

        Technical notes
        The data-decoupled 30 V AS-i output and separate 24 V auxiliary output on Siemens 3RX9306-1AA00 must remain on their assigned conductors.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why does 3RX9306-1AA00 power auxiliary devices but not establish AS-i communication?
        Measure the 3RX9306-1AA00 30 V AS-i output, verify profile-cable polarity and data decoupling, and check the master, addressing, and network short circuits.
        Why is the 24 V output of 3RX9306-1AA00 present while the AS-i voltage is low?
        Separate the 3RX9306-1AA00 output loads, inspect the AS-i cable for overload or short circuit, and confirm the 4 A network-current limit.
        What must be checked before changing the mains selector on 3RX9306-1AA00?
        Isolate 3RX9306-1AA00, confirm the actual source voltage, select the matching 115 or 230 V range, and verify the branch protection before re-energizing.
        Why does 3RX9306-1AA00 shut down after additional AS-i slaves are connected?
        Total the 3RX9306-1AA00 network current, inspect cable voltage drop and shorts, and keep the AS-i load within the documented 4 A output.
        Can the two DC outputs of 3RX9306-1AA00 be paralleled?
        No. The 3RX9306-1AA00 30 V AS-i and 24 V auxiliary paths have different functions and must remain on their assigned circuits.
