Description
Description
Monitor and control temperatureor process applications withprecision using the CN142 Seriescontrollers. The CN142 Seriesprovides dual LED displays forlocal indication of process valueand setpoint value. Controlmethods include on/off, PID,auto-tune and manual-tune.Controller includes a 3 setpointramp/soak control feature, andalso includes alarm, event andtimer functions with optionalRS485 communications. Anoptional software packageCN-SW-HW-KIT includes cableand configuration module for quickconfiguration of units, as well ascopying configuration parametersfrom one unit to another. Theconfiguration module can alsobe purchased separately andwith a built-in battery feature,configuration settings can bedownloaded and copied to themodule without power appliedto controller. The module canthen be plugged into a new unitwithout power applied and theconfiguration setting can betransferred for easy set-up formultiple units.
