The MIK-311 is a universal microprocessor-based controller designed for automatic regulation and monitoring of technological parameters in industrial processes. It supports both manual and automatic control of process variables such as temperature, pressure, level, humidity, flow, and other physical values across various industrial sectors.

⚙️ Functional Capabilities:

📊 Measurement and Indication:

  • One universal input for measuring temperature or other physical values (pressure, humidity, flow, level, etc.) using sensors with standardized current or voltage outputs. Switching to another sensor type does not require recalibration.
  • Dedicated input for thermocouple signal compensation.
  • Real-time indication of measured values and control status.
  • Input scaling for each measurement channel.
  • Digital signal filtering and correction.

📈 Control Modes:

  • Maintains stable process values according to setpoints.
  • Supports:
    • PID control with auto-tuning (analog, pulse, and PWM);
    • Two-position (ON/OFF) and three-position control;
    • Manual control via the front panel.
  • Generation of control signals for actuators (e.g., solenoid valves, SSRs, VFDs).

🚨 Alarm Functions:

  • Alarm triggering when measured values exceed preset limits, activating discrete outputs.
  • Linear conversion of input signals to standardized analog output signals.
