    The MM200 includes high accuracy metering of current signals. Current parameters are available as total RMS magnitude.

    Digital Counters
    The MM200 provides ten digital counters to aid in system analysis. The digital counters can be used for scheduling inspections on equipment, performing qualitative analysis of system problems and spotting trends.

    Learned Data
    Monitoring the motor’s operating characteristics assists in determining the motor start parameters and is a critical tool for determining the operating characteristics of the system, motor and connected load.

    Advanced Device Health Diagnostics
    The MM200 performs comprehensive device health diagnostic tests during startup and continuously at runtime to test its own major functions and critical hardware. These diagnostic tests monitor for conditions that could impact the MM200’s performance, evaluate the criticality of this impact and present device status via SCADA communications. Providing continuous monitoring and early detection of possible issues helps improve system availability by employing predictive maintenance

    The Hand Held Display (HHD) provides a rugged local interface for MM200 Motor Protection Systems where a local display is not used in the MCC.
    The HHD provides a graphical color local interface to the MM200 Motor Protection Systems allowing local operators to view and change setting files and quickly access relay diagnostic information.
    The HHD provides a clear and detailed view of all motor settings, diagnostic information and metering data available in the MM200 allowing local operators to make informed decisions on the motors operation.
