LT110 Series Digital Indicating Controller

LT110 series is 48×24mm size compact indicating controller. It is suitable for various systems such as semiconductor manufacturing equipment, electronic parts manufacturing equipment, food processing machine, packaging machine, molding machine etc.

  • Compact, lightweight, and space-saving
    The controller is vary small so it is effective for down sizing systems and control panel.
  • Full multiple range
    Thermocouples 5-types, and RTD 4-types, multiple range input is available.
  • PID auto tuning function
  • Various functions convenient for temperature control
    Functions such as sensor correction, set value lock, set value limit, control output OFF, alarm activation delay timer etc.
  • Conforming to CE marking and IP-65.
    The controller is conforming to European safety standard CE marking and front part complies with IEC standard IP65 dust and drip proof structure.
