CONTROLLER BY TECHNOLOGICAL PROCESSES 

The controller by technological processes is indented for organization of remote switching ON/OFF,controlling and measuring up to 8 (with opportunity to increase up to 24), and regulation up to 8 (with opportunity to increase up to 16) parameters.

Provides the following types of adjustment:

  • manual (by inserted the necessary value);
  • automatic (the algorithm and value of limits of adjustable parameters are set ). The accuracy of adjustment depends on the given algorithm.

 

The main units of the controller are:
  • micro-controller (MC) with analog-digital converter based on pulse-duration modulation (ADC-PDM);
  • analog-digital converter based on pulse-code modulation (ADC);
  • nonvolatile RM;
  • interface of sequential standard ports RS-232 and RS-485;
  • interface of control and indication (ICI). Consists of the keyboard (16 keys) and liquid-crystal detector (LCD) with lighting control;
  • analog commutator (AC);
  • clock with RAM;
  • attenuator (Att);
  • analog filter and level converter (AFLC);
  • keys (photon-coupled and transistor).
