Temperature Control/PID Modules

Temperature Control/PID Modules (F3CU04-0S / F3CU04-1S)

Versatile control at high speed, accuracy and resolution

This module enables fine control at high speed,
accuracy and resolution.
Its built-in "SUPER" function suppresses overshooting
using fuzzy theory to deliver improved manufacturing quality.
Its superior functions and performance can be easily
harnessed using its "dynamic auto-tuning" function or setup tool.

High-Speed, High-Accuracy, High-Resolution
- Input sampling cycle : 100 ms/2 CH, 200   ms/4 CH
- Input accuracy : ±0.1% of F.S.
-Input resolution : 0.1℃ (5-digit display)

Universal Input 
A single module can be used to support a variety of inputs (thermocouple, RTD, DC mV and DC V), selectable for each channel. By configuring individual channels to separate inputs, it delivers high efficiency at low cost. 

  

Dyanamic Auto-tuning Function

 - With a user setting the minimum number of parameters (such as input/output range and 
   control set point), this module automatically calculates the optimal PID parameters to
   simplify startup preparation, saving tuning effort and cost.
 - It even recalculates the PID parameters automatically when there is a major change in the
   control condition (i.e. change in control set point) during operation.
