Product Description for Siemens 6ES7400\u20111JA11\u20110AA0 SIMATIC S7\u2011400 Rack Module<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
6ES7400\u20111JA11\u20110AA0 is a brand\u2011new original aluminum\u2011made UR2 rack belonging to SIMATIC S7\u2011400 PLC system. It serves as the fundamental mechanical and back\u2011plane bus carrier for S7\u2011400 controllers. This UR2 rack contains 9 module slots and supports both central rack (CR) and distributed expansion\u2011rack (ER) installation modes. It can accommodate two S7\u2011400 power\u2011supply modules for redundant power configuration, as well as CPU modules, communication processors, digital and analogue I\/O modules and interface modules. The built\u2011in P\u2011bus and K\u2011bus transmit power and high\u2011speed bus signals among all plugged\u2011in modules. It builds the hardware foundation for high\u2011end PLC control systems widely deployed in petro\u2011chemical plants, power stations, metallurgy equipment, large\u2011scale production lines and PCS7 process\u2011control projects. The whole rack is mounted inside industrial control cabinets and forms a compact modular\u2011structure S7\u2011400 automation system.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Mechanical Fixing and Positioning\n
    <\/div>\n

    It provides standard slot positions to firmly install S7\u2011400 series modules. Anti\u2011vibration aluminum\u2011alloy structure prevents modules from loosening under workshop vibration conditions.<\/li>\n

  2. Back\u2011Plane Bus Transmission\n
    <\/div>\n

    Integrated P\u2011bus (Process bus) and K\u2011bus (Communication bus) deliver 5\u202fV DC power, internal data signals and MPI communication signals between all inserted modules.<\/li>\n

  3. Redundant Power\u2011supply Support\n
    <\/div>\n

    Two PS407 power\u2011supply modules can be mounted on this rack. Hot\u2011standby redundant power supply ensures continuous system running when one power\u2011supply unit fails.<\/li>\n

  4. System Expansion Realization\n
    <\/div>\n

    When used as an expansion rack together with IM460\u2011IM461 interface modules, it expands installation slots away from the central rack to reduce long\u2011distance wiring.<\/li>\n

  5. Heat\u2011Dissipation Structure\n
    <\/div>\n

    Aluminum profile accelerates heat dissipation for CPUs and high\u2011power modules, avoiding overheating failures for long\u2011term continuous operation.<\/li>\n

  6. Compatibility Guarantee\n
    <\/div>\n

    It matches all standard S7\u2011400 series modules and works with STEP\u20117 software for hardware configuration and system diagnosis.<\/li>\n

  7. Galvanic Isolation Design\n
    <\/div>\n

    Internal bus structure isolates field\u2011side interference to protect back\u2011plane circuits against surge currents from high\u2011power actuators.<\/li>\n<\/ol>\n<\/div>\n
