Main features
Analog output and external contact input are added to the CB series
![](https://www.rkcinst.co.jp/english/wp-content/uploads/sites/2/2019/02/cb103403903_02_01_01e.jpg)
Analog outputs and digital inputs are available.
Control state discriminating type self-tuning
![](https://www.rkcinst.co.jp/english/wp-content/uploads/sites/2/2019/02/self_tune_01_01_01e.jpg)
PID parameters are automatically tuned when control is determined to be disturbed
Autotuning function is also available.
Close mounting is available
