Additional Feature

The CN7200 Series ¼DIN temperature/process controllers are designed to accept thermocouple, RTD, current or voltage input and provide dual outputs for control. Available outputs include relay/relay, DC pulse/relay, current/relay, or linear voltage/relay. The units can be programmed for ON/OFF, PID, auto-tuning, or manual tuning control methods. The PID control is supported by 64 ramp/soak actions. The CN7200 Series also includes two additional alarm outputs. The second relay output can be reconfigured as a third alarm output. The alarm type can be selected from 13 different preprogrammed alarm functions. The controller features dual LED displays for local indication of process and setpoint values.

For product CN7653, Dual output, 4 to 20 mA/relay with RS485* means that the PID can control temperature by adjusting a current (4 A to 20 mA)?

Asked by: abcdef
Hi, thanks for your question. Yes, output #1 is an analog control output that can be programmed using the PID tuning parameters to control your process. You can either manually tune the PID values, or use autotune, providing the process is for temperature and you have a set point at least 100 degrees (C or F) above your starting ambient temperature. Please email us at with any further questions.

Hi, I am trying to run the CN7-A software with my Omega 7800 and my computer is recognizing it as a device and will not read it as a com port, clicking on the device states that there are no available drivers. please help

Asked by: ashley
Hi Ashley, Thank you for the inquiry. The CN7800 series have RS485 output requiring RS485 to USB adapter for most pc's. Please contact our temperature tech support by email TEMP@OMEGA.COM or call 800-359-1660 and select post sales for technical support. Best regards OMEGA
