Description

Comment fonctionnent les Régulateurs de température

Les régulateurs de température série CN740 offrent des mesures et une régulation précises de la température, dans un boîtier DIN 1?16. Conçus pour une action directe ou inverse (chauffage ou refroidissement), ils peuvent être programmés pour commander la fonction marche/arrêt et recevoir des fonctions de commande PID plus complexes. La commande par PID permet un réglage manuel ou automatique. Sélectionnez la sortie à relais, les impulsions CC ou la sortie en intensité comme méthodes de commande. La série CN740 accepte des signaux d'entrée de différents thermocouples et sondes RTD. La valeur mesurée et la valeur de seuil s'affichent simultanément sur l'affichage double à LED. Le panneau avant indique également le type de réglage (manuel/auto), l'unité de mesure (°F ou °C) et l'état de l'alarme. Chaque unité comprend deux sorties d'alarme et 12 fonctions d'alarme préprogrammées.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from 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.

Rated 4 out of 5 by from 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.

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?

Asked by: Smed
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?

Asked by: ajrs
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?

Asked by: Kathy E
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.

Asked by: Ravi09
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

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).

Does CN743 require SSR? Can you please explain connection in video? By the Data file i can not understand the connections.

Asked by: Ravi09
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.
