The CN740 Series temperaturecontrollers offer accurate temperaturemeasurement and control in a1.16 DIN package. Designed for director reverse acting (cooling orheating) control, the CN740 Seriescan be programmed for simpleON/OFF or more complex PIDcontrol functions. PID control issupported with manual orautotuning. Select relay, DCpulse or current output for controlmethods. The CN740 Seriesaccepts a variety of thermocoupleand RTD inputs. Process valueand set-point value are displayedsimultaneously on the large dualLED. Auto-tuning, engineeringunits (°F or °C), and alarm statusis also indicated on the faceplate.Two alarm outputs are includedon the unit with 12 preprogrammedalarm functions.
