Description

La gamme de contrôleurs PID basés sur microprocesseur de la série Platinum offre une flexibilité inégalée dans la mesure de procédé. Bien qu'ils soient extrêmement puissants et polyvalents, ces contrôleurs ont été conçus avec le plus grand soin afin de simplifier leur utilisation et configuration. La reconnaissance automatique de la configuration du matériel élimine le besoin de cavaliers et permet au micrologiciel de se simplifier automatiquement, supprimant ainsi toutes les options de menu ne s'appliquant pas à une configuration spécifique. Disponibles en trois tailles : 1?32, 1?16 et ? DIN. Les modèles 1?16 et ? DIN peuvent être configurés en double affichage.
Chaque unité permet à l'utilisateur de choisir le type de sorties à partir de neuf types de thermocouples (J, K, T, E, R, S, B, C et N), des RTD Pt (100, 500 or 1 000 ? avec courbe 385, 392 ou 3 916), des thermistances (2 250 ?, 5K ? et 10K ?) ou entre la tension CC ou le courant continu CC. Les entrées de tension ou de courant sont bipolaires et entièrement adaptables à presque toutes les unités d'ingénierie avec décimal sélectionnable, idéal pour une utilisation avec pression, débit ou autre entrée de procédé.
Le contrôle peut être effectué en utilisant la stratégie de contrôle marche/arrêt ou PID chauffage/refroidissement. Le contrôle PID peut être optimisée grâce à une fonction de réglage automatique et, de plus, un mode de réglage adaptable à logique floue permet à l'algorithme PID d'être optimisé en permanence. L'instrument offre jusqu'à 16 segments de rampe et palier par programme rampe et palier, avec des actions d'événements auxiliaires disponibles sur chaque segment. Jusqu'à 99 programmes enregistrés pouvant être chaînés pour créer jusqu'à 1 584 segments discrets. Plusieurs alarmes peuvent être configurées au-dessus, en dessous, haut/bas et par déclenchement de bande en utilisant les seuils de déclenchement d'alarme absolus ou de déviation.
Le périphérique de la série Platinum est doté d'un grand affichage programmable à trois couleurs, avec fonction de changement de couleur et/ou de l'état des sorties désignées à chaque fois qu'une alarme est déclenchée. Plusieurs configurations de relais mécanique, de SSR, d'impulsion CC et de sorties analogiques sous tension ou alimentées en courant sont disponibles. Chaque périphérique est livré en standard avec module de communication USB pour les mises à jour du micrologiciel, la gestion de configuration et le transfert de données. Ethernet en option (modèles 1?16 DIN et ? DIN uniquement) et communication série RS232/RS485 sont également disponibles. La sortie analogique est entièrement échelonnable et peut être configurée comme un contrôleur proportionnel ou une retransmission pour assurer le suivi des données affichées. L'alimentation universelle est compatible avec une tension de 90 à 240 Vca. L'option d'alimentation basse tension est compatible avec une alimentation de 24 Vca ou de 12 à 36 Vcc.
D'autres fonctions généralement présentes sur des contrôleurs plus coûteux font de ce périphérique le produit le plus puissant de sa catégorie. Certaines de ces fonctions standard supplémentaires sont : point de consigne distant pour des configurations du contrôle en cascade, fonction d'alarme haut-haut/bas-bas, réinitialisation du verrouillage externe, initiation externe de programme rampe et palier, mode de commande combinée chauffage/refroidissement, enregistrement et transfert de configuration, et protection de mot de passe de configuration.
Communications Ethernet et série intégrées
L'option « Ethernet intégré » sur les modèles 1?16 et ? DIN permet aux périphériques de se connecter directement à un réseau Ethernet et de transmettre des données par paquet TCP/IP standard ou même de créer des pages Web via un LAN ou Internet. L'option Communication série est également disponible et configurable en RS232 ou RS485 avec de simples commandes ASCII ou MODBUS®. Les trois types d'interfaces de communication (USB, Ethernet et série) peuvent être installés et activés en même temps.
Contrôle en cascade
La fonction Point de consigne distant des contrôleurs de la série PLATINIUM peut être utilisée dans diverses applications où des consignes peuvent être envoyées aux contrôleurs à partir des périphériques distants comme les potentiomètres manuels, les transmetteurs, les ordinateurs, etc. Cette fonction peut également être utilisée pour configurer un système de « contrôle en cascade » où l'entrée du point de consigne distant est générée par un autre contrôleur. La figure 1 ci-dessous montre un schéma générique d'un système de contrôle en cascade et la figure 2 montre un exemple typique, dans le cas présent une application d'échangeur de chaleur.
Les systèmes de contrôle en cascade peuvent permettre un contrôle plus stricte d'un procédé lorsque vous disposez de deux variables liées, dont l'une présentant un temps de réaction beaucoup plus lent (généralement 4 X ou plus) que l'autre. La variable au temps de réaction plus lent est utilisée comme l'entrée au contrôleur primaire ou principal et celle à réponse plus rapide est utilisée comme entrée au contrôleur secondaire ou esclave. La sortie du contrôleur principal est échelonnée pour être utilisée comme point de consigne pour le contrôleur secondaire.
En ce qui concerne l'application d'échangeur de chaleur (voir figure 2), sa fonction principale est de contrôler la température des effluents. Par conséquent, la température désirée des effluents devient le point de consigne pour le contrôleur primaire, qui est un contrôleur de température (TC). L'entrée de procédé du contrôleur de température est la température enregistrée des effluents (TT). La sortie du contrôleur de température est le point de consigne de débit du contrôleur, qui est un contrôleur de débit (FC). L'entrée de procédé du contrôleur (de débit) secondaire est le débit de la vapeur utilisé pour chauffer le débit de procédé au moyen de l'échangeur de chaleur (FT). La sortie du contrôleur (de débit) secondaire est un signal de commande pour la vanne proportionnelle régulant le débit de la vapeur.
En isolant la boucle de contrôle de la température à lente évolution des effluents de la boucle de contrôle de débit en évolution rapide, un système de contrôle plus prévisible, robuste et strict est obtenu.

Rated 5 out of 5 by from Great technical support We have put this to use. The technical support is what allowed us to put this into use quickly.

Rated 1 out of 5 by from Very difficult to use THS S HW YU PRGM AN OMGA CNTRLR. This is 2017. Why does the 'Platinum' temp controller have a 1980s user interface? The USB port is an afterthought in a terrible location. It would not stay connected to my computer. The software does not run in Windows 10, and is not supported by Omega. Omega makes a lot of good products, but this is not one of them. We sent the unit back.

Rated 1 out of 5 by from A nightmare to control from a computer The device itself might be ok but it was a nightmare to control it from a computer. Prepare to get head-hakes. The technical documentations are poorly written, very difficult to understand and filled with errors. It required a lot of of time and trials/errors to understand which commands and parameters to send. It was more like reverse engineering the communication protocol than using it ! What a lost of time. For some unknown reason, several "Omega ASCII protocol" commands didn't work. So don't use it. Their Modbus LabVIEW examples are buggy. Looks like a summer student wrote them. What a joke. And absolutely no answer from the technical support. Nothing. What a shame.

Rated 3 out of 5 by from Works, but not without issues Bought two controllers and ran into issues with both, readings jumped all over the place during testing. Opened up the controller and found that the input board wasn't mounted onto the main board properly for both, wasted a good amount of time trying to troubleshoot. Once I re-seated the internal board it worked as intended.

Rated 5 out of 5 by from Best controller I have a handful of the older i16 and i32 controllers in use already, and am replacing two of those with pt32 (one done, one in progress). The i32 were already very good, with useful features, although a somewhat clunky setup interface (the 4-button menus could make grown men cry). Reliability has been perfect. Communication was a bit of an issue, required going to the larger 1/16 DIN model in some cases. The pt32 has fixed all that. Even when using the four buttons, the setup is now more logical. But the sane way to set them up is to connect them to a laptop and configure them with the Platinum program. Being able to upload and download configurations means that I can finally put the configurations under revision control, and check that the device installed in the system is actually configured correctly. I can also modify configurations offline, without taking the control system down, and then quickly upload them in a quick downtime. Once you have a configuration, it can be quickly adjusted by editing the txt file directly. All very very convenient. With the USB port, the communication problem has been solved. Find something with a USB connector nearby (laptop, industrial controller), either write a few lines of Python or install LabView, and you can chat with the controller. I'm now using the controller as an A-D converter for computer analysis of the process too. Very cool, low cost, convenient. Speaking of cost: The Newport/Omega controllers have never been cheap, but worth their price. If you need a simple low-feature controller, buy something else. The few times I've talked to tech support (in Santa Ana), they've been very helpful, patient, and knowledgeable. My only complaint is: In one case I need four setpoints and four outputs from a single input; while it is theoretically possible to get this many outputs (not clear it can be ordered in a 1/32 DIN, that would be model -444-776), there are not four setpoints available. So this needs to be handled by using two controllers. Expensive, but works great.

Rated 3 out of 5 by from OK OK unit. Omega missed ship date by weeks. PC configuration software didn't work without lots of futzing around. LED display is straight out of the 90's. But, works well once configured, build quality looks good, optimistic about reliable performance. Having two PID loops in one controller is nice too.

Rated 4 out of 5 by from Good product. but need to improve usability. Need better software for monitor and control the controller. we also want there are easier way that we can export process values to further analysis

Rated 2 out of 5 by from Product okay, omega horrible! Product is good, omega service and website is horrible! Used to be good 5 years ago, now just superficial marketing and poor technical info for identifying specific product specs. Looking for another supplier.

We have been using the CN16Pt-330 unit for LN2 cooling. While it does work, the only way to control cooling is to use reverse action on the outputs, which is simple on/off, not PID control. Is there another controller that will control cooling with PID?

Asked by: Ed at Thermal Space
The CNPT series is capable of utilizing PID control for cooling applications. The action should be set for direct and the mode selected for PID. If there are questions contact the Temperature group at temp@omega.com.

Can I use this controller to maintain a heater to a variable set point temperature? The goal is to always have a sample an offset temperature from the ambient air.

Asked by: EGAtlas
Yes, if you have mA or voltage signal as input for our platinum series controller. Use the remote setpoint input feature. Then use the control offset "Ofst" function.

Is there a way to add an offset to the temperature controller just like in the older models like the CN76000?

Asked by: Vic19
Yes in the INit menu there is a parameter t.cal that allows a single point offset to be entered so your reading can match a reference.

Does this model have an over set point temperature alarm or any method handling a over setpoint temperature? Looking to have the output latch off in the case of going over the set point temperature by 5 or 10 deg F. Thanks!

Asked by: ErikG
If you use the Analog output for your control loop you have a SPDT relay to use to set alarm conditions. The alarm can be used to change the color of the display or switch a light or audible device or tie to a contactor to cut current flow to your output device. It is recommended from a safety point of view to not do this because the temperature sensor is shared and if it fails your alarm relay may not work properly. A separate Limit Controller with an independent sensor is the advised way to configure for maximum safety.

I'm using CN16DPT-144, that has 3 outputs and 1 input for thermocouple. Can I control two difference processes for temperature control with two difference setpoints? But how to use two thermocouples for feedback?

Asked by: Maxy
Thank you for you inquiry Annony. Even though this controller has 3 outputs, you can only control one load at a time due to having only one input. You will need two controllers to control two difference processes.
