Description

Monitor and control temperature or process applications with precision using the CN142 Series controllers. The CN142 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, and also includes alarm, event and timer functions with optional RS485 communications. 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.

Rated 5 out of 5 by from Works out of the box. Very versatile. After setting up the parameters correctly for my sensor and for dual mode operation, the auto tune drove the process right to set point and locked it there. No fuss.

Rated 5 out of 5 by from Good little unit I have only bench tested the CN142 so far, but it is working well. I'm using it to control a pellet feeder and igniter on a BBQ smoker. I needed a replacement controller with a variable process period so that I could minimize temperature surges in the smoker. The igniter is controlled via the alarm relay and turns off once the smoker has come up to temperature.
