Multifunctional Module MOUVON MFM

MOUVON-MFM is an intelligent controller that has been designed to control tree-phase electric motors with power 1 - 250kW.



The analogue inputs PhR_CurrMeas and Ph_R measure the current and the voltage of one of the phases. The input signals are received from a voltage step-down isolation transformer (220/15V) and from a current transformer (Ix/0,5A). The incoming values serve as an indicator for the trouble-free operation of the motor and for the calculation of the consumed power.
The analogue output Curr_Out is included for the frequency control of the motor (which requires input signal of 4-20mA for the motor speed).
The inputs Ph_R, Ph_S and Ph_T are detecting the failure of phases and ensuring the correct phase sequence (R – S - T). The logic blocs built into each device indicate if one (or more) phases fail or the phase sequence of the motor is incorrect.
The input Dig_In - A is included for starting the motor manually (which is controlled according to the technological tasks by built-in software).
The input Dig_in – B is motor status feedback.
Initiation of the motor is controlled by a digital output Dig_Out signal through a contactor (or an interstitial  relay).

  • Protection class: IP20
  • Functions
    • Аnalogue inputs: 3
      • 12bit voltage/frequency tranformer;
      • 839 ms measurement time for every one chanel.
        AI_1 – direct input: up 0 to + 2,5V or ± 2,5V  (possibly temperature measurement up –40°C to +125°C by TMP36 Analog Devices’ sensor)  
        AI_2 – input: ± 25,0V AC/DC 0Hz – 1000Hz (fixed range with pre-tuning possibility)
        AI_3 – input: ± 0,5V AC/DC 0Hz – 1000Hz (fixed range with pre-tuning possibility).
      • Аnalogue outputs: 1
        АО_1 – voltage output: 4 – 20mA or 0 – 20mA (according to the requirements); Resolution: 8/16 bit; Passive (with an external power supply  +36V max.); Load resistivity:  RL ? 1,5k?.
        The device has an errors’ light indicator (such as: the max. value of the output voltage at 20mA  coudn’t be reached because of lack of  power or because of exceeding the max. resistance of charge value as well  the resistance of the wires).
