Les régulateurs de température de la série CN740 offrent une mesure et un contrôle précis de la température dans un boîtier 1/16 DIN. Conçue pour un contrôle direct ou inverse (refroidissement ou chauffage), la série CN740 peut être programmée pour des fonctions de contrôle ON/OFF simples ou des fonctions de contrôle PID plus complexes. Le contrôle PID est pris en charge avec un réglage manuel ou automatique. Sélectionnez la sortie relais, impulsion CC ou courant pour les méthodes de contrôle. La série CN740 accepte une variété d'entrées thermocouples et RTD. La valeur du processus et la valeur de consigne sont affichées simultanément sur la grande double LED. Le réglage automatique, les unités techniques (°F ou °C) et l'état de l'alarme sont également indiqués sur la plaque frontale. L'appareil comprend deux sorties d'alarme avec 12 fonctions d'alarme préprogrammées.

inexpensive, works well.
I use this controller to maintain the temp in a molten salt furnace. With the auto tune it holds a constant temp with minimal over shoot and fast reaction time.

Reliability is marginal
Originally had six units, three failed after 1 year. The internal relay contacts became intermittent, one fused in the "on" position. They are only switching 2 amps, and are rated for 5.

CN9000A Replacement
Perfect replacement to the CN9000A, to be used in a NASCAR Oil Temperature Heater control for warming the engine oil and circulation before the engine is started. With this ability we don't have keep as close as an eye on the oil temperature in the tank while working this process that takes approximately 1 hour.

1/16 DIN Temperature Controllers
Product works well and can easily be integrated with most controls systems. The only complaint is that the lead time is often quite long if the items are not in stock.

Controller features have On/Off and PID Control
Because this controller has both On/Off & PID Control I was able to configure it to my oven.

Great Service
Bought this recently and pleased that I did, it performs as advertised.

Does Omega certify or if necessary, re-calibrate the CN742 controller for temperature and 4-to-20MA output. Target temp. is 80F. Does a new controller come certified?
Thank you for your inquiry. We do not re-calibrate this unit.

Is the relay output just a simple on/off signal? Is the DC Pulse a PWM signal, and, if so, what is the duty cycle and frequency range?
Hi AJRS,
Both relay and pulse outputs can be used as PID control. Output is based on cycle time not PWM and is set by user. Cycle time down to 1 second is available. But fastest relay cycle time should limited to 7 to 10 seconds.
Best regards

Can this model be used for over-temperature protection?
Hi Kathy,
The CN743 would not be recommended for use as a limit controller. The CN2516-R1 would be a 1/16 DIN size controller that would be suited for use as an over-temperature limit controller. It has the ability to latch which is what you'll want as a feature in a true limit controller.

Can you please share connection for CN743 with out SSR? I need to connect it with out using SSR. Please share the power supply connection for this.
Thank you for your inquiry. Due to this being a more complicated issue please call 1-888-826-6342, ask for Temperature Engineering or send an email to temp@omega.com

Does CN740 comes with mounting bracket?
Thank you for your inquiry. The mounting bracket is included.

I would like to speak with a technical rep regarding the operation of the CN74-3 temp controller. I am Working from Home (WFH). I do not have controller in front of me (located 34 miles from here).
Thank you for your inquiry. Feel free to call our Temperature Group at 1-888-826-6342 to discuss application. We are available until 6:30 EST

Does cn743 model comply with REACH and RoHS ?
Thank you for your inquiry. Unfortunately this product does not comply with RoHS and/or REACH.
Date published: 2022-07-07
Does CN743 require SSR? Can you please explain connection in video? By the Data file i can not understand the connections.
Thank you for the inquiry. The answer will depend on if your load pulls over the maximum current rating for the CN743's relay, which is 5 Amps. If your load pulls under 5 Amps, you will not require an SSR.
