Main features

Control state discriminating type self-tuning

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

Autotuning function is also available.

Closely contacted mounting is available

Closely contacted mounting has been realized to efficiently utilize the panel space.

Communication function (RS-485) is available (Optional)

Up to 31 controllers can be multidrop connected over the RS-485 communication line.

Communication protocol can be selected from RKC standard or MODBUS protocol.
