Built for industrial process control, this temperature/process controller is supplied with Analog Current, Cool. It has accuracy of ±0.2% of full scale, ± digit. It also suits heating and cooling regulation.
Built for industrial process control, this temperature/process controller is supplied with Analog Current, Cool. It has accuracy of ±0.2% of full scale, ± digit. It also suits heating and cooling regulation.
The CN8500 temperature controller is extremely versatile and user-friendly. The operator needs to review only those parameters relevant to the particular application during setup.
A dual digital display offers optimum process information at a glance. The dedicated upper display shows the process temperature, while the lower display displays setpoint and setup parameters.
