Rotary Motion Electric Actuator
MRP10, PRP10, PRP11 for torque 6-200 Nm

  • Stepping motor drive
  • High-speed operation control with 1/1000 resolution
  • 4-20 mA output plus Modbus-RTU communication for control and maintenance
  • Terminal box with transparent cover equipped with operating status indicator LEDs
  • Operator access to the terminal box only
  • Auto-Setup Function
    (linear motion type)
    The time and effort required to adjust the valve opening is greatly reduced.
    Those for maintenance work can be also saved.
    Auto-Setup Function (linear motion type)
  • Modbus Communication
    Directly connectable to PLC/PC network
    Actuators' operation data can be accumulated while in the normal operation.

  • TERMINAL BOX

  • Easy wiring

    The terminal box is separate from the main unit to make wiring work easier.

    Operation can be checked at a glance

    LEDs for operating status indicator can be checked through the rugged, transparent polycarbonate cover.

    Easy parameter setting

    Various parameters can be set with DIP switches or by using the Programming Unit (Model: PU-2A) connected to the modular jack in the terminal box, without opening the cover of the main actuator body. In addition, parameters can also be set from a PC using the configurator software (Model: STCFG).*1

Diagnostic Information Improves Equipment Maintainability and Reduces Costs

  • Diagnostic information is more than just real-time condition monitoring; it is important data for determining the timing and type of necessary maintenance. Because it can be used for both predictive and preventive maintenance, diagnostic information helps minimize downtime and extend the service life of equipment.

    Actuator operating status can be checked from the STEPTOP PC Configurator Software (Model: STCFG) screen or via Modbus＊1.

  • Opening data analysis example

    Opening position distribution data displays the distribution of the output stem open position to operating hours and can be used as a reference when considering valve sizing optimization.

  • Benefits of valve optimization

    　
    Improved control accuracy
    Greater flow control stability and improved process characteristics
    System stabilization
    Reduced problems by preventing overloads and abnormal operation
    Energy conservation
    Reduced energy loss due to improperly sized valves
    Extended equipment life
    Optimized operation for reduced valve and actuator wear
    Cost reductions
    Reduced frequency of unnecessary maintenance and replacement cost
