        Overview Manuals Source Decoupling Load Connection Terminal Sizing Altitude Derating

        Features:

        • Two positive DC input paths are decoupled before reaching one load output.
        • The module handles 12–48 V DC systems and up to 40 A output current.
        • Spring terminals and TH35 rail mounting carry the high-current wiring arrangement.
        Siemens 6EP4347-7RB00-0AX0 occupies the junction between two upstream SITOP supplies and a single protected DC load path.

        Its internal voltage drop is approximately 0.6 V, so downstream voltage follows whichever input branch is delivering power.

        Redundancy depends on two correctly separated source feeds; DC OUT1 is the common connection toward the load.

        The Siemens 6EP4347-7RB00-0AX0 SITOP RED1200 40 A Redundancy Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 6EP4347-7RB00-0AX0 SITOP RED1200 Redundancy Module 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.

        Two-Input Redundancy Path

        • First branch: The positive output of one supply terminates at DC IN1.
        • Second branch: A separate supply positive terminates at DC IN2.
        • Electrical separation: The internal decoupling stage prevents the two source positives from becoming one direct connection.
        • Redundant result: Either available branch can continue feeding the common output path.

        DC OUT1 Current Flow

        • Output terminal: DC OUT1 is wired toward the downstream load.
        • Voltage relation: Load voltage is approximately 0.6 V below the conducting input.
        • Current ceiling: The common path carries up to 40 A across the documented input range.
        • Temporary margin: A 120% current level is permitted from -40 to +45 °C.

        High-Current Conductor Interface

        • Terminal type: Spring-loaded clamps secure the two inputs and the output.
        • Solid conductor: Solid wiring may range from 0.75 to 16 mm².
        • Flexible conductor: Finely stranded wiring may range from 0.75 to 25 mm².
        • Wiring boundary: Each source lead and the load lead retains its own terminal position.

        Environmental Operating Limit

        • Normal altitude: The standard operating data applies through 2000 m above sea level.
        • Higher sites: Operation can extend to 6000 m with the documented derating.
        • Current option: Output may be reduced by 7.5% for each additional 1000 m.
        • Temperature option: The ambient limit may instead be lowered by 5 K for each additional 1000 m.
        Description
        Rather than generating a new control voltage, Siemens 6EP4347-7RB00-0AX0 sits between two DC power supplies and the load as a SITOP RED1200 redundancy module. The positive output of each upstream supply enters separately at DC IN1 or DC IN2, preventing the two source paths from being directly joined.

        The load connects to DC OUT1 on 6EP4347-7RB00-0AX0. Input may range from 10 to 58 V DC around the 12–48 V rating, and the module passes as much as 40 A while the output remains approximately 0.6 V below the active input path because of the internal decoupling stage.

        During operation from -40 to +45 °C, 6EP4347-7RB00-0AX0 permits 120% of rated output current. The two input paths allow one supply branch to remain separated from the other; this relationship forms the redundant feed, while the downstream equipment receives one combined load connection rather than two independently switched outputs.

        Spring-loaded terminals on 6EP4347-7RB00-0AX0 accept the high-current input and output conductors before the module snaps onto a TH35 rail. The IP20, Class III enclosure operates from -40 to +70 °C under natural convection, and installations above 2000 m must apply the documented current or ambient-temperature derating.

        Technical notes
        Siemens 6EP4347-7RB00-0AX0 accepts the positive output from each source at DC IN1 and DC IN2 and feeds the load from DC OUT1; it is a decoupling module, not a stand-alone power supply.

        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
        Is 6EP4347-7RB00-0AX0 a 24 V power supply by itself?
        No. 6EP4347-7RB00-0AX0 is a redundancy module; it receives power from two external DC supplies and decouples their positive paths before feeding the load.
        Where should the load be connected on 6EP4347-7RB00-0AX0?
        Connect the downstream load to DC OUT1 on 6EP4347-7RB00-0AX0, while the two upstream supply positives connect separately to DC IN1 and DC IN2.
        Why is the voltage after 6EP4347-7RB00-0AX0 lower than the supply setting?
        The internal decoupling path of 6EP4347-7RB00-0AX0 produces an approximate 0.6 V drop, so the load voltage follows the active input minus that value.
        Can each input of 6EP4347-7RB00-0AX0 carry 40 A at the same time?
        The specified output boundary for 6EP4347-7RB00-0AX0 is 40 A total. Size each source branch for the intended redundant arrangement rather than treating the module as two independent 40 A outputs.
        Which conductor sizes fit the spring terminals of 6EP4347-7RB00-0AX0?
        6EP4347-7RB00-0AX0 accepts 0.75–16 mm² solid conductors or 0.75–25 mm² finely stranded conductors at its input and output terminals.
        What changes above 2000 m for 6EP4347-7RB00-0AX0?
        For 6EP4347-7RB00-0AX0 above 2000 m, apply either 7.5% output derating or a 5 K ambient-temperature reduction for each additional 1000 m, up to the documented 6000 m limit.
