Decent little controller
These little controllers come with a good array of features for the price. However, the mounting clips they come with are cheap, easily broken, and very difficult to get replacements without ordering a whole new controller.

Great Temp Controller
Controller was easy to install and program. It’s operation is simple and efficient. Very good quality build. I will use this brand for process controllers moving forward.

Is the relay electromechanical or solid state? Is the relay enclosed?
The CN733 has one Relay: SPST, 5A @ 250 Vac resistive. Thanks for connecting with Omega. Please contact our Tech Support with any further questions.

For the Current Output option, when the controller is tuned correctly, is the 4-20mA output altered to maintain the setpoint or is it just a constant pulse?
Thank you for your inquiry DJ92. A 4-20 mA output changes depending on how close or far away you are from the setpoint. Therefore, a 4-20 mA is not a constant pulse.

I can no longer enter auto tune. When I get to the AT selection, I can't select ON. Is there some way to restore auto tune functionality?
Hi Anonymous,
Please check that you are in PID mode and not in the Program mode for ramp soak.
Best regards
OMEGA
