      Information

      Information

      Overview Manuals Common Applications Product Precautions
      In a matched Series 500 base, Siemens 500-2151 converts the documented 110/220 VAC source into the regulated rails required by the controller and installed I/O.
      • Serves as the AC base power supply for Series 500 hardware.
      • Uses the documented 110/220 VAC installation supply.
      • Provides a +5 V rail rated at 54 W.
      • Provides a -5 V rail rated at 3.75 W.

      Evaluate the incoming AC arrangement and every connected base load before exchange. A successful repair requires stable +5 V and -5 V rails together with a clean base startup.

      Important Notice: Do not apply specifications from 500-2151-A; the installed record and nameplate must identify the exact 500-2151 execution.

      The first document defines the exact Series 500 power-supply boundary; the second organizes AC-source checks, rail measurements, loading review and base-startup acceptance.

      Series 500 base renewal
      Restores regulated power to a controller base that is documented for 500-2151.
      AC-source compatibility
      Supports maintenance where the recorded installation uses the approved 110/220 VAC arrangement.
      Rail-voltage troubleshooting
      Separates incoming-power faults from +5 V or -5 V distribution problems.
      Loaded-base acceptance
      Confirms both regulated rails while the original controller and I/O load is connected.
      Work on 500-2151 only after the Series 500 base and its AC source are identified. Treat the supply and every connected load as one power system.
      1
      Verify 500-2151 rather than the separate 500-2151-A variant.
      2
      Confirm the documented 110/220 VAC installation arrangement.
      3
      Isolate incoming AC and prove the base de-energized.
      4
      Record line, neutral, protective-earth and output connections.
      5
      Inspect the base for shorts or abnormal loading before power-up.
      6
      Measure the +5 V and -5 V rails with the correct reference.
      7
      Observe the controller and I/O startup for supply instability.
      8
      Release only after rail voltages remain stable under load.

      Technical notes

      Technical notes

      Match Siemens 500-2151 to the complete installed record, host position and companion hardware. Preserve connections and settings; then verify diagnostics and regulated base power for a matched SIMATIC TI500 or TI505 installation under controlled conditions.

      FAQS

      • What does 500-2151 identify?
        500-2151 identifies the series 500 ac power supply used for regulated base power for a matched SIMATIC TI500 or TI505 installation.
      • Which installed system must 500-2151 match?
        Match 500-2151 to the recorded SIMATIC TI500 / TI505 host, position and companion hardware.
      • Which markings must be checked on 500-2151?
        Verify the complete 500-2151 text and every suffix, revision or assembly marking on the supplied item.
      • What should be recorded before removing 500-2151?
        Record the slot, connectors, cable labels, switches, parameters, adjacent hardware and diagnostic state.
      • Can 500-2151 be replaced by appearance alone?
        No. 500-2151 requires an exact identity and interface match against the installed-system record.
      • How should 500-2151 be isolated?
        Use the approved maintenance state, remove connected energy and prove the affected circuit safe.
      • What is checked after installing 500-2151?
        Check mechanical seating, wiring, settings, communication, diagnostics and every affected function.
      • What releases 500-2151 to service?
        A recorded acceptance test must confirm regulated base power for a matched SIMATIC TI500 or TI505 installation without unexpected alarms or process response.
