Functional circuit

Functional circuit 

The technological controlling measuring unit:

  • measures analog signals from flow rate, level, temperature and other sensors (the VP module); 
  • controls the measured parameter according to the two-point (relay) rule (the MK module);
  • calculates the square root from the measured parameter (MKM unit);
  • displays the current value of the measured parameter at the built-in LED digital display (the MIK module);
  • forms uniformed output signals of DC power within ranges of  0…5 mА, 4…20 mА, 0…20 mА to record the measured data or to control actuation devices (the MAV module);
  • displays measured values on the personal computer (hereinafter referred to as the PC) and adjusts the controller to the PC via the RS-485 or RS-232 interface (the MI module);
  • feeds sensors with the uniformed output signals or other devices via the current loop from the built-in power source (BPS).
Controlling logics

The measuring controller may include up to five galvanically isolated commutation channels.

Commutation is done using:

  • relay;
  • optical relay;
  • optical bidirectional triode thyristor.

Controlling signals are programmably calculated and depend on current states of the relay, the value of the measured input signal, fixed set-point, hysteresis values and logics of the commutation channel operation.

For each commutation channel, you may determine the response logics after receipt of signals from each threshold device.
