MIK-312 is a universal microprocessor-based controller with a timer and advanced PID control functions, designed for automatic control and monitoring of process parameters in industrial applications 🏭. It supports manual and automatic control of parameters such as temperature, pressure, level, humidity, flow rate, and other physical values that can be converted by sensors into a standardized analog signal.

⚙️ Key Functions

🧩 Measurement & Signal Processing

  • Supports multiple sensor types: thermocouples, RTDs, and sensors with standard analog outputs (current/voltage) for pressure, level, etc. 
  • Scaling and mathematical processing of the measured signal 
  • Input linearization to compensate for non-linear sensor/transmitter characteristics 
  • Sensor type switching without calibration (software-supported input types) 
  • Manual calibration of analog inputs and analog output (if required) 

🎛️ Control Algorithms

  • Analog PID control (continuous control output via analog output) 
  • Pulse PID control (Up/Down
  • PID PWM heating control — power control using variable pulse width 
  • Two-position control (ON/OFF) with adjustable hysteresis 
  • Three-position control (open/close/stop) for reversible actuators 
  • PID Auto-Tuning — automatic PID parameter calculation for fast commissioning 

🎯 Setpoint & Mode Management

  • Setpoint (SP) adjustment and correction, including external signal/condition influence 
  • Ratio control mode — control based on a defined proportion 
  • Setpoint bank — store and quickly select operating setpoints/modes 

⏱️ Timer & Time-Based Modes

  • Time-based operation: delay, cyclic operation, and control using time intervals 

🚨 Alarms & Limit Monitoring

  • Monitoring of parameter limits: high/low thresholds, warning/alarm modes 
  • Alarms can be sent to discrete outputs and/or transmitted to upper-level systems 

🖥️ Configuration & Automation System Integration

  • Configuration via the front panel 
  • Service and configuration via USB and RS-485 
  • Integration into PLC/SCADA systems via RS-485 (Modbus RTU) 

🕹️ Remote (External) Control

  • External control using two discrete signals (Auto/Stop, Auto/Manual, setpoint selection, etc. — depending on configuration)
