Rated 3 out of 5 by Dave AGCA from Outstanding controller, abysmal manual. This would be a 5+ star product if it weren't for the extraordinarily poor manual. This is a complex controller with a tremendous number of features and settings that can handle very difficult process control problems easily...once you figure out how to use it. Technical support, while very well meaning and committed to helping, was of not much assistance as they also relied on the same manual, and generally suggested "reading the manual" as a way out. I wouldn't have called if I hadn't read the manual. I will admit, that I am old, but I have been using Omega controllers for decades with few problems. The descriptions in the manual for this excellent controller were abysmal.

Rated 1 out of 5 by qusai from DONT DO THSI TO YOURSELF! Extremely hard to program. You don't want to be spending hours just trying to program a simple step heating process and it still not working. Instructions aren't the best. There is no sense of hierarchy in the instruction steps nor a clear description of what each term means.

Rated 5 out of 5 by West O Beer from Already purchased a second time Controller was shipped and received quickly, works perfectly for our temp control at the brewery.

Rated 5 out of 5 by Ian B from Capable, Simple, Affordable Controller Handy little controller that has worked flawlessly so far. Installed to replace the failing electronics in a drying oven and found it easy to adapt to relatively low temperature use with the appropriate limits and alarms. Has brought control temperatures (using the same sensor) within 2C of the setpoint compared to 10C with the older electronics.

Rated 1 out of 5 by Oyvind from DON'T The unit was so hard to program that even with Omega engineers helping/instructing me over the phone I could not get it to work. After 4 calls and about 8 hours on the phone I gave up.

Rated 5 out of 5 by Jamar Mechanical from Very Reliable I could not locate the OEM controller, so I called Dwyer/Omega after speaking with their product specialest they were able to quickly come up with the controller that turns out to work better then the OEM one that it replaced, also giving me a feature which was an issue with the OEM controller which was to lock out the controler at different levels, enabling the user to only access what is needed, so for me, this controller was the way to go, Thank you Dwyer/ Omega

Rated 4 out of 5 by AcmeVial from CND3 Temperature Controller Great features for the price, especially the Auto-Tune feature. The manual it comes with is not very helpful so don't expect it to teach you how to set up a Temperature Controller. The online manuals are slightly better. Once you wrap you head around the programming aspect it's a great controller.

Rated 4 out of 5 by J Williams from Great Controller Great controller but Tech Support thru "Contact Support" on website had little knowledge of how to help with controller functions. Some trial and error, and too much manual reading to make it do what I wanted.

CND3-Series

1/16, 1/8, and 1/4 DIN Temperature and Process PID Controllers

Is output 1 the linear V output. Is it max 250V @ 5amp? Can it work on a contactor with a 110/120V coil?

Hi. CN16D3-L-AC PDI controller, What ore the outputs options and if more than one. How do I change the output mode.

Can the CN16D3-M-DC float since it is being suppled with 24 V DC?

Can the variables, in particular P, be negative?

Do you have a heater contactor for running (2) 1500 Watt, 240 VAC heaters ? Need (2) contactors each rated for 10 or 15A, in an enclosure.

omega recommend a cm16d3-m-ac controller how do i hook up wires to retransmit temperature signal to a plc

Hi, Model CN16D3-M-AC --> Can you confirm this would work connecting the DC output of controller to the control of a SSR model SSRL240DC10? thx!

What is the depth of the CN16D3-M-AC controller? Could not find the info in the manual or via chat.
