1. Main feature Advanced operation method leads to easy learning and simple manipulation; and the compatibility of operation is available among the instruments differ in the model and function. Provide nearly all of the functions contained by most similar industry automatic controller in the world, and the mature technique made it generally used in various kinds of industrial fields. Provide various models that can meet different needs either in the functions or price. With power supply of 85-264vac or 24vdc and various installation dimensions for users to choose. Adopt digital calibration system for measurement input with measurement input accuracy less then 0.2% f.S., non-linear calibration for common sensors is 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, equipped with plentiful output specifications, and can satisfy the needs of various applications. This makes it possible to shorten the date of delivery and convenience the maintenance of the instrument.  having the predominant performance of anti-interference. 2.
