Rated 3 out of 5 by 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 4 out of 5 by from Powerful, Compact, bit tricky to learn Works well, good features, bit tricky to program until reading on line manual. The included paper document is not clear about the button press timings to activate the three different menus.. Increasing and decreasing temperatures a bit slow as numbers increment and decrement slow as you hold the button. Bubble membrane buttons are not so easy to use they are so small, and require significant pressure to activate. You have to hold the little head unit I installed them in from moving as you press. Seems to hold temperatures very nicely, display is nice. Overall it is a very nice feature packed unit, and fairly easy to use once you figure it out.

Rated 5 out of 5 by from good quality temperature controller This instrument does exactly what I want and is very stable. It is easy to program as long as you follow the flow chart provided.

Rated 1 out of 5 by 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 from Great device for the cost Great little device for the money. I used it to heat a battery at a specific ramp rate until failure. Once it ran through its autotune, it held VERY accurately to that ramp rate. It takes a bit to learn all the functions, but once you know the features you need regularly it becomes straight forward. It has a lot more functionality than I think I'd ever need.

Rated 5 out of 5 by from Nice price to feature ratio. Easy to use, very good cost to feature ratio. Ramp functions are very useful, would have been nice to have finer resolution on ramp timing, but it works quite well.

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

Asked by: JFWp
Thank you for your inquiry! The depth needed for the panel cutout is 79.7mm. If you need the depth for the entire controller itself please reach out to temp@omega.com.

What the screen displays on start up does not match anything I see in the manual. Is there a set up guide? The manual does not include a set up guide.

Asked by: Robertf
Hi Rob, Thank you for the inquiry. Sorry, that we do not have strart up. Manual goes directly in to set up pages. Please see the manual page 3. Refers to the 3 modes Regulation, Operation, and Initial Setting modes and how to navigate between modes. https://assets.omega.com/manuals/M-CND3.pdf Best regards OMEGA

The manual (p13) talks about setting the "control period". Exactly which parameter is this? Thank you

Asked by: sketel
The Control Period is the period of PID operation, if the control period is 10s, it means a PID operation is carried out every 10s. The result is then output to control the temperature. If the system heats up quickly, the control period shall not be set too long. For relay output, the lifespan of the relay shall be considered; a short period will shorten the lifespan of relay. Parameter "o1-H, o1-C, o2-H, o2-C"

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.

Asked by: Iceman
Hi Iceman, Thank you for the inquiry. Our control relays are currently limited to 10 A service; https://br.omega.com/omegaFiles/auto/pdf/XTRE_SERIES.pdf https://www.omega.com/en-us/communication-and-connectivity/interface-cards/electromechanical-relays/xtre-series/p/XTRE10B40A Best regards OMEGA

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

Asked by: james o
The output of this controller is a 'powered output' so simply run terminal # 5 (+) to the Positive input of your PLC, and #4 (-) to the Negative input of your 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!

Asked by: directandrew
Hi Directandrew, This will not work. You'll need the version with DC pulse; CN16D3-S-AC. Best regards, Omega

On the manual it lists the factory setting for the temperature lower limit is -200C, does that mean that it can accurately measure values at -200C and then heat up to room temperature? We are trying to use this controller with a low temperature system.

Asked by: Finn1384
This unit can control process temps to -200 C accurately if the sensor accuracy is compatible with the temperature range as well. Example of compatible sensor is the PT100 RTD. And example probe is ; PR-11-2-100-1/8-12-E Thank you for your question.
