The MIK-22 Dual-Channel Microprocessor Controller is designed for automatic regulation and monitoring of technological parameters in industrial processes. It provides both manual and automatic control of parameters such as temperature, pressure, level, humidity, flow, and other physical quantities across various industrial sectors. The device includes two independent PID controllers.

⚙️ Functional Capabilities:

📊 Measurement and Indication:

  • Two universal inputs for measuring temperature or other physical quantities (pressure, humidity, flow, level, etc.). Sensor type switching does not require recalibration;
  • Switching to another sensor type is possible but requires calibration and changing jumper positions on the input board;
  • Indication of current values and control process status;
  • Input signal scaling;
  • Digital filtering and signal correction.

📈 Control Modes:

  • Two independent PID controllers;
  • Maintains stable parameter values according to defined setpoints;
  • Supports:
    • PID control: analog, pulse, and PWM;
    • Two-position (ON/OFF) and three-position control;
  • Manual control from the device’s front panel;
  • Output signal generation for actuators (e.g., solenoid valves, solid-state relays, frequency converters).

🚨 Alarm Functions:

  • Alarm function for out-of-range process variables, with discrete output activation;
  • Linear conversion of input signal into a standardized analog output signal.
