Product Description for Siemens 7KM9300\u20110AB01\u20110AA0 PROFIBUS\u2011DP Expansion Module<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
7KM9300\u20110AB01\u20110AA0 is a new\u2011original plug\u2011in communication expansion module under Siemens SENTRON product series. It is exclusively designed for 7KM PAC3220, PAC4220 power monitoring meters and 3VA COM100\/COM800 circuit\u2011breaker communication modules. This module provides PROFIBUS\u2011DP V1\/V2 interface for power measuring devices, enabling PAC meters to transmit real\u2011time electrical parameters, energy consumption data, demand values and device diagnostic data to upper\u2011level PLC systems such as S7\u2011300, S7\u2011400 and S7\u20111500 via PROFIBUS\u2011DP field\u2011bus. It gets power supply directly from the host PAC meter without separate external power supply. It adopts compact plug\u2011in design for quick installation without extra wiring work inside low\u2011voltage switchgear cabinets. It is widely used in factory power\u2011distribution rooms, commercial building power monitoring systems, data\u2011center power distribution equipment and industrial workshops for energy\u2011management and power\u2011data acquisition. This module complies with IEC\u201161158 PROFIBUS\u2011DP standard and is manufactured in HungaryNEX Instru….<\/div>\n<\/div>\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. PROFIBUS\u2011DP Communication Connection\n
    <\/div>\n

    It converts internal data signals of PAC power meters into standard PROFIBUS\u2011DP protocol data, supports baud\u2011rate from 9.6 kbit\/s up to 12 Mbit\/s, works as PROFIBUS\u2011DP slave station and exchanges cyclic input and output data with DP master PLCs. It supports DPV1 acyclic services for parameter configuration and advanced diagnosisNEX Instru….<\/li>\n

  2. Galvanic Isolation Protection\n
    <\/div>\n

    Built\u2011in 500 V AC electrical isolation separates internal meter circuits and external PROFIBUS\u2011DP bus circuits to block ground\u2011loop current and suppress electromagnetic interference produced by variable\u2011frequency drives and high\u2011power motors. It protects power meters from external surge damage.<\/li>\n

  3. Real\u2011Time Data Upload\n
    <\/div>\n

    Transmits measuring data including voltage, current, power factor, active energy, reactive energy and peak demand to central PLC or SCADA systems for energy\u2011cost allocation, power\u2011quality analysis and power\u2011consumption statistics.<\/li>\n

  4. Diagnostic Indication Function\n
    <\/div>\n

    A DIAG LED indicator displays module running status, bus connection status and communication faults. Fault codes can be read via PLC program to help maintenance staff find bus breakdown or communication\u2011failure problems quickly.<\/li>\n

  5. Plug\u2011and\u2011Play Installation\n
    <\/div>\n

    Module can be inserted into the reserved expansion slot of PAC meters without tools. After installation, the host meter automatically identifies this communication module without manual hardware setting.<\/li>\n

  6. Compatibility with Siemens Automation System\n
    <\/div>\n

    It cooperates with STEP7 and TIA Portal software for hardware configuration, parameter setting and online monitoring, matching perfectly with the whole SIMATIC automation platform.<\/li>\n

  7. Stable Long\u2011term Operation\n
    <\/div>\n

    It adapts to cabinet\u2011installation environment and continuously runs 24\u2011hours\u2011a\u2011day for long\u2011term power\u2011monitoring tasks without frequent maintenance.<\/li>\n<\/ol>\n<\/div>\n
