Working Principle
PT100 RTD temperature sensor mounted on rolling mill roller transmits surface temperature measurement signal to module analog input circuit. Onboard PID processor compares measured temperature against user-configured setpoint value, modulating output power drive to roller heating elements via pulse-width modulation (PWM) control signal. Proprietary fieldbus communication continuously transmits real-time temperature data and fault status to central Komatsu rolling mill master PLC control system. Hardware thermal threshold circuit immediately cuts heating power upon exceeding maximum safe roller temperature limit to avoid mechanical equipment deformation failure.
Advantage Highlights
- ±0.5 °C ultra-precise temperature regulation eliminates inconsistent steel slab surface finish defects
- Heavy-duty galvanized steel enclosure withstands continuous rolling mill mechanical vibration and steel mill corrosive airborne particulate environment
- Integrated hardware over-temperature protection prevents costly roller mechanical damage events
- Native Komatsu mill fieldbus compatibility eliminates external communication gateway conversion hardware
- Long 6-year manufacturer certified service warranty for continuous 24/7 mill production operation
Applicable Industries
Hot steel slab rolling mills, aluminum alloy continuous casting rolling production lines, metal plate hot forming manufacturing plants
Installation Requirements
- Securely bolt-mount module inside IP40+ sealed rolling mill main electrical control cabinet
- Separate heating element high-current output wiring and low-voltage PT100 sensor signal wiring via cabinet cable partitions
- Supply stabilized 24 V DC SELV industrial control power to module power input terminals
- Maintain minimum 30 mm airflow clearance surrounding unit enclosure for continuous heat dissipation
Usage Precautions
- Do not exceed 6 A maximum channel heating drive current rating to avoid internal power circuit burnout
- Conduct monthly PT100 sensor wiring continuity diagnostic testing to prevent loss of temperature feedback control
- Clean enclosure ventilation filter panels weekly to remove accumulated steel mill conductive metal dust buildup
- Replace only with factory-original AIH-123QS-PP-UC control modules; non-Komatsu certified units void mill equipment production warranty
- Do not operate module with cabinet ambient temperature exceeding maximum +55 °C rating
