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.

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.

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?

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

When making a pattern with many steps, I see we can choose the temperature and time of each step and set an initial slope. However, this slope applies to all the steps. Is it possible to give each step a different slope so I can have different rates?

Asked by: ktb1165
Hi KTB1165, Thank you for the inquiry. Recipes consist of Setpoint (SP) and time (Ti) to the set point. Ramp rate is determined by the initial SP to final SP difference and the time Ti to the target. Best regards, OMEGA

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.
