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.

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

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.

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.

do you have an example of setting up a pattern in the CND3 controller? I have set the pattern 0, turned on prog mode. Put system in RUN, it just heats and heats. Does the pattern wait to hit temperature before moving on

Asked by: Kirkllwork
Thank you for the inquiry. Please forward this in an email to TEMP@OMEGA.COM so that we can help you trouble shoot the problem. Note; Start you first target temperature to ambient room temp. Best regards OMEGA

Does this Alarm stay latched and not be able to be reset if it is in an alarm condition. Example: Target heating SP of 800F and alarm high set at 1000F. If the PV is at 1050F, can you reset the alarm function? Same with a low temp alarm for cooling?

Asked by: ronb
Thank you for your inquiry. Alarms can be reset by activating the F1/F2 Buttons as reset.

Does the derivative control mode actually work in these controller's? I purchased 6 of the 1/32 Din's with no derivative action - to verify, we set Kd to max with no effect on controller output.

I have a CN08D3-L-AC controller. The manual describes a "remote mode" that would allow the setting value to be controlled with a 0-10V analog signal. Can I add this feature by adding a remote board to the controller? If so, what is the part number?

Asked by: bmendelson
Thank you for your inquiry. The unit can accept the signal directly. No extra hardware needed.

Is the SYNC Configuration Software used to configure the CN16D3-MR-2U-CM-AC. Can the setting in the instrument be saved to disk and downloaded into another like instrument.

Asked by: gharter
Hi Gharter, Thank you for the inquiry. SYNC program does not work with this controller. If you purchase the RS485 option with this controller you can use the free software linked up next to manuals on this web page. You would also need an RS485 to USB converter for your PC. Please forward questions on CND3 series software to TEMP@OMEGA.COM 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"

I have an AC device (CN16D3-LR-2U-CM-AC) rated at 100-240 V. How do I go about powering it? My device didn't include a power supply, but I noticed the rating matches the average outlet voltage, can it be powered directly without a transformer?

Asked by: ChemResearcher
Thank you for your inquiry. This controller is designed to be panel mounted and hard wired to the rear screw terminals with standard AC power (100 - 240 VAC). A power supply or transformer is not required.

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

Asked by: Tennessee1074
Thank you for your inquiry Tennessee1074. The 250 Vac @ 5 A output you are referring to is for the relay output of the controller. Yes, it can handle any voltage below 250 Vac as long the current rating of the load is below 5 A.
