The CN740 Series temperature controllers offer accurate temperature measurement and control in a 1/16 DIN package. Designed for direct or reverse acting (cooling or heating) control, the CN740 Series can be programmed for simple ON/OFF or more complex PID control functions. PID control is supported with manual or autotuning. Select relay, DC pulse or current output for control methods. The CN740 Series accepts a variety of thermocouple and RTD inputs. Process value and set-point value are displayed simultaneously on the large dual LED. Auto-tuning, engineering units (°F or °C), and alarm status is also indicated on the faceplate. Two alarm outputs are included on the unit with 12 preprogrammed alarm functions.
