Designed for cooling control and networked temperature monitoring via rs485, this temperature controller provides 4 to 20 mA. 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.
