        More Information

        Overview Manuals Power Distribution Station Position Supply Connections Version Matching

        Features:

        • A 24 V DC input supplies the ET 200iSP station through the designated power-module position.
        • Separate internal paths feed the power bus, interface-module bus and station backplane.
        • The 7EA00 order suffix identifies the original PS DC 24V hardware release.
        The PS DC 24V module forms the supply entry point for the distributed I/O station rather than an ordinary signal channel.

        Its terminal-module position routes the incoming source toward the interface and electronic modules installed to its right.

        Station planning must retain the full order number because the later 7EA01 release is a different catalog item.

        The Siemens 6ES7138-7EA00-0AA0 ET 200iSP Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 6ES7138-7EA00-0AA0 ET 200iSP Power Supply 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.

        Routing supply through the ET 200iSP station

        • Supply entry: The station 24 V DC source enters through the terminal module assigned to the power supply.
        • Power bus: One internal path distributes operating power to the station components that use the ET 200iSP power bus.
        • Interface path: A separate path supplies the installed interface module at the head of the distributed I/O station.
        • Backplane path: The backplane supply supports communication and operation across the installed electronic modules.

        Locating the power module before the I/O modules

        • Supply slot: The PS module is installed in the designated supply section of the ET 200iSP station.
        • Downstream modules: The interface and electronic modules receive their station services after the supply path is established.
        • Terminal base: Field wiring terminates on the matching terminal module rather than directly on a loose power module.
        • Order control: The station parts list should retain 7EA00 to separate this release from 7EA01.

        Keeping incoming and internal power paths distinct

        • External source: The documented input is a 24 V DC station supply.
        • Internal distribution: The module converts the incoming connection into the ET 200iSP power, interface and backplane paths.
        • Field boundary: External supply conductors end at the terminal-module connection assigned to the PS position.
        • Station check: A wiring review should follow the terminal-module assignment for this complete order number.

        Distinguishing the original PS DC 24V release

        • Exact suffix: 7EA00 identifies this product and must not be shortened to a generic 6ES7138 entry.
        • Later release: 7EA01 is listed separately in Siemens ET 200iSP documentation.
        • Product role: Both the product name and brief description identify 7EA00 as a PS DC 24V supply.
        • Record accuracy: Keeping the complete order number prevents station records from mixing the two hardware releases.
        Description
        Siemens 6ES7138-7EA00-0AA0 is the PS DC 24 V power-supply submodule for the SIMATIC ET 200iSP distributed I/O station. Plugged into a TM-PS-A or TM-PS-B terminal module, it converts the incoming station supply into the output-voltage paths required by the ET 200iSP modules.

        Power for 6ES7138-7EA00-0AA0 enters through L+ and M on the terminal module, while the PA terminal connects the station equipotential-bonding conductor. Its output voltages are electrically isolated from the 24 V input and from one another, so the power bus, backplane bus and interface-module supply remain separated from the incoming circuit.

        When 6ES7138-7EA00-0AA0 is installed in a hazardous area, the enclosure and wiring arrangement depend on the zone. Zone 1 requires an EEx e enclosure, Zone 2 requires at least IP54, and intrinsically safe conductors must be routed separately from non-intrinsically safe conductors.

        Electrical protection for 6ES7138-7EA00-0AA0 includes reverse-polarity protection and 600 V DC insulation testing between the supply input and all output voltages. At the specified 24 V input, the module can draw up to 4 A, dissipate 20 W and accept no more than 78.6 W of input power.

        Technical notes
        Siemens 6ES7138-7EA00-0AA0 is the original ET 200iSP PS DC 24V version. Keep the complete 7EA00 suffix when checking the terminal-module and station configuration.

        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 can 6ES7138-7EA00-0AA0 not be treated as an ET 200iSP signal module?
        The 6ES7138-7EA00-0AA0 is the station power supply; it establishes power for the buses and interface section rather than reading or switching field channels.
        Where does 6ES7138-7EA00-0AA0 sit in an ET 200iSP station?
        The 6ES7138-7EA00-0AA0 belongs in the designated power-supply position on its matching terminal module, ahead of the downstream station modules.
        What must be checked before wiring 6ES7138-7EA00-0AA0?
        Confirm the 24 V DC source, terminal-module assignment and complete 7EA00 order number before wiring 6ES7138-7EA00-0AA0.
        Does 6ES7138-7EA00-0AA0 supply only the interface module?
        No. The 6ES7138-7EA00-0AA0 establishes power paths for the station power bus, interface-module bus and backplane bus.
        How is 6ES7138-7EA00-0AA0 separated from the later PS DC 24V version?
        Use the full suffix: 6ES7138-7EA00-0AA0 is listed separately from 6ES7138-7EA01-0AA0.
        Why should the terminal base be recorded with 6ES7138-7EA00-0AA0?
        Field supply wiring lands on the assigned terminal module, so recording that base with 6ES7138-7EA00-0AA0 preserves the station wiring relationship.
