Monitor and control temperature orprocess applications with precisionusing the CN245 Series DIN railmountable controllers. The CN245Series provides dual LED displaysfor local indication of processvalue and setpoint value. Controlmethods include on/off, PID,auto-tune and manual-tune.Controller includes a 3 setpointramp/soak control feature, alarmfunctions, RS485 communicationsand heater loop break alarm.Beside operation as multi-setpointPID controller, the unit can beideally used as signal converterthanks to a universal input(selectable by parameter for upto 18 different signals) and theanalog output which is galvanicallyisolated and programmable forrescalable retransmission ofprocess/setpoint value.An optional 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 modulewithout power applied to controller.Module can then be plugged intoa new unit without power appliedand the configuration setting canbe transferred for easy set up formultiple units.
