With DC Pulse, this temperature controller is used for industrial process temperature control and cooling control. It has inputs of Thermocouple, RTD, see chart.
With DC Pulse, this temperature controller is used for industrial process temperature control and cooling control. It has inputs of Thermocouple, RTD, see chart.
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.
