Product Specs

This product has reached the end of it's life cycle but a replacement will be released soon!

Temperature Controller with Thermistor Inputs that allows you to monitor and control temperature or process applications with precision. The CN243 Series provides dual LED displays for local indication of process value and setpoint value. Control methods include on/off, PID, auto-tune and manual-tune. Controller includes a 3-setpoint ramp/soak control feature, alarm functions with optional RS485 communications heater loop break alarm. Analog output can be programmed for either control or retransmission of process variable. An optional software package CN-SW-HW-KIT includes cable and configuration module for quick configuration of units, as well as copying configuration parameters from one unit to another. The configuration module can also be purchased separately and with a built-in battery feature, configuration settings can be downloaded and copied to the module without power applied to controller. The module can then be plugged into a new unit without power applied and the configuration setting can be transferred for easy set-up for multiple units.
