High Accuracy
The series are manufactured with custom designed ASIC(Application
Specific Integrated Circuit ) technology which contains a 18-bit A to
D converter for high resolution measurement ( true 0.1 F resolution
for thermocouple and PT100 ) and a 15-bit D to A converter for linear
current or voltage control output. The ASIC technology provides
improved operating performance, low cost, enhanced reliability and
higher density.

Fast Sampling Rate
Fast Sampling Rate
The sampling rate of the input A to D converter reaches 5 times/second.
The fast sampling rate allows this series to control fast processes.
Fuzzy Control
Fuzzy Control
The function of Fuzzy control is to adjust PID parameters from time to
time in order to make manipulation output value more flexible and
adaptive to various processes. The results is to enable a process to
reach a predetermined set point in the shortest time, with the minimum
of overshoot and undershoot during power-up or external load
disturbance.
