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.

Analog Retransmission Output function is available (Optional)

• The output 1 can be configured as an analog  retransmission output. 

With this function, the measured value can be  retransmitted as an analog current signal  (4-20mA /0-20mA).

Two types of colors; black base or white base

• Two types of colors are offered to match the machine.

Please note that Shop RKC America, our online store, is exclusively available for

customers residing in the United States, Canada, and Mexico.
