Main features

Analog output and external contact input are added to the CB series

Analog outputs and digital inputs are available.

Control state discriminating type self-tuning

PID parameters are automatically tuned when control is determined to be disturbed

Autotuning function is also available.

Close mounting is available

Close mounting has been realized to efficiently utilize the panel space.
