PID Controller AI 518 / AI 519:

  • Adopt digital calibration technology for input measurement with input measurement accuracy 0.3% F.S., non-linear calibration tables for standard thermocouples and RTDs are available in the instrument.
  • Adopt advanced AI artificial intelligence control algorithm, no overshoot and with the function of auto tuning and self-adaptation.
  • Adopt advanced modular structure, conveniently providing plentiful output options, can satisfy the requirements of various applications, and make quick delivery and conveniences the maintenance of the instrument.
  • Friendly and customized operating interface leads to easy learning and simple manipulation. Any parameter can be promoted to immediate operator access in Field Parameter Table or password protected in Full Parameter Table.
  • With worldwide power supply of 100-240VAC or 24VDC and various installation dimensions for users to choose.
  • High quality and performance hardware design, using high performance tantalum capacitor or ceramic capacitor. Compared to competing models, it consumes less electricity, experiences less temperature shifting, provides higher stability and reliability, and can work in a wider range of temperature.
  • ISO: 9001 and CE Certified, achieving world class level of quality, anti-interference ability and safety.
