The CN7200 Series 1/4;DIN temperature/process controllers are designed to accept thermocouple, RTD, current or voltage input and provide dual outputs for control. Available outputs include relay/relay, DC pulse/relay, current/relay, or linear voltage/relay. The units can be programmed for ON/OFF, PID, auto-tuning, or manual tuning control methods. The PID control is supported by 64 ramp/soak actions. The CN7200 Series also includes two additional alarm outputs. The second relay output can be reconfigured as a third alarm output. The alarm type can be selected from 13 different preprogrammed alarm functions. The controller features dual LED displays for local indication of process and setpoint values.

Rated 4 out of 5 by Good Controller from Good controller. Good controller. Good controller. Good controller.

Rated 2 out of 5 by Perplexed from Could be a much more user-friendly instrument Although the CN7233 temperature controller that I purchased works, I cannot in good conscience award it any more than a 2 out of 5 stars due to inadequate documentation, bizarre display hieroglyphics, and some questionable logic affecting the user interface. The application is controlling a single-zone pottery kiln - about as simple as it gets. The feature that attracted my attention to the CN7233 is that it can have as many as 8 separate programs (patterns?) in memory with as many as 8 steps in each program (pattern). The documentation in both the Instruction Sheet included with the instrument and the Specifications - Installation and Operating Instructions available on-line fall short in presenting a concise, cogent set of instructions on how to set up, tune, and operate the controller. One item that is missing in the documentation is any detailed description on how to tune the instrument - no examples or other guidance to address this important feature, particularly for the ramp/soak function. The only substantive direction comes from the bold-face warning on page 11 of bulletin E-90-OCN which states: "Do not operate auto-tuning while a ramp function is operating. The ramp function will prevent self tune from operating properly. Make sure that all tuning is set up before operating ramp/soak". And then there is the word "off" found in Link parameter on page 12. What I discovered the hard way is that "Off" really means "On" unless there is an unused step at the end of a pattern. Where is the absolute "end" function? And "SP" doesn't mean set point, but rather where the decimal point goes. The display, IMO, is simply weird. A type K thermocouple is depicted as a reversed lower case "y". "r-S" is where one goes to find the "run" button as well as the "stop" button. The stop button is somewhat important because that is how one selects the program (pattern) to be used for the operation. Is that logical? The CN7233 could be a much better value if both the instructions and the user interface were cleaned up.

Rated 5 out of 5 by Sergei Hanukovich from Controller Works as Expected Works as expected, circuit diagram easy to read and overall design is standard, but nice. Interface is not immediately straightforward, but manual does good job of breaking all the functions down in a clear way. Technical support was helpful in determining the the PID controller that best suited my application needs.

Rated 4 out of 5 by Anonymous from Good for general lab use Fills my light/medium-duty heating and cooling needs. I use it to control metallurgy furnaces, PVD process heaters, hydrogen furnaces and a coolant bath for electrochemistry synthesis. It takes some time to acclimate to the old shcool user-interface, but it's not a deal-breaker. The auto-tune feature helps to keep the process temperature within one degree C when implemented properly.

1/4 DIN Ramp/Soak Temperature/Process Controllers

On the free software can I program the Ramp/Soak that I would like on the computer or does that have to be done directly on the controller itself

Does the CN7633 1/8DIN vertical controller use fuzzy logic?

Documentation says free software for Item# CN7823--- how do I get it?

Hello, where can I find the MODBUS register descrption for this CN7823 controller?

For product CN7653, Dual output, 4 to 20 mA/relay with RS485* means that the PID can control temperature by adjusting a current (4 A to 20 mA)?

Hi, I am looking for MTBF data for CN76153. Where can I get this data? Thank you.

Hi, I am trying to run the CN7-A software with my Omega 7800 and my computer is recognizing it as a device and will not read it as a com port, clicking on the device states that there are no available drivers. please help

We are currently in need of a controller for a 4-wire RTD PT100, with a 1/16 DIN format. Could you please provide information on the available options?
