Main features

48(W)×24(H)mm sized compact temperature controller

Compact size controller that can be mounted on a small panel space

Large easy-to-read PV display on a compact front panel

Control state discriminating type self-tuning

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

Autotuning function is also available.

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.

Two types of colors; black base or white base

Two types of colors are offered to match the machine.
