Rated 5 out of 5 by no0ne 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 Bcarlton 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 quantum 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 ProcEng 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 RalphBSz 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 grumpy engineer 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 Jacky 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 5 out of 5 by Mario Zorrilla from CNPT 1/32 and 1/16 I have used the 1/32 and 1/16 CNPT controllers, and these have proven to be very robust. What I like the most is the possibility to communicate to a PC because I mostly use LabView for integrating them and automating a process
