The Platinum Series family of microprocessor-based PID controllers offer unparalleled flexibility in process measurement. While extremely powerful and versatile, great care has gone into designing a product that is very easy to set-up and use. The automatic hardware configuration recognition eliminates the need for jumpers and allows the firmware to automatically simplify itself, eliminating all menu options that do not apply to a specific configuration. Offered in 1⁄32, 1⁄16, and 1⁄8 DIN sizes, the 1⁄16 and 1⁄8 DIN models can be configured with dual displays.
 

 



Each unit allows the user to select the input type from 9 thermocouple types, PRT/RTD sensors, thermistors, DC voltage, DC current, and Strain & Bridge inputs. The full bidirectional voltage or current inputs are fully scalable to virtually all engineering units, with a selectable decimal point that is perfect for use with pressure, flow, or other process input.

Up to 6 programmable outputs including the isolated analogue and additional features make this the most powerful product in its class. Standard features include: remote set-point for cascaded control, high-high/low-low alarms, external latch reset, external ramp and soak initiation, combination heat/cool control mode and configuration save and transfer.

Free Downloadable Software

  • Fully Configure all PLATINUM Functions/Parameters
  • Auto-Connect Through USB Channel
  • Load/Save PLATINUM Configuration Files
  • Performance Tracking (Charting) with Data Capture

An advanced multi-stage ramp and soak sequencer supports up to 99 profiles of 8 segment ramp/soak sequences. Profiles may be linked to provide extended sequences and auxiliary outputs may be triggered based on individual Ramp or Soak states to provide external control over blowers, mixers or other auxiliary control functions.

Embedded Ethernet and Serial Communications
Optional “embedded ethernet” on the 1⁄16 and 1⁄8 DIN models allow the units to connect directly to an Ethernet network and transmit data in standard TCP/IP packets, or serve Web pages over a LAN or the Internet. Optional serial communications are also available configurable as RS232 or RS485, with straightforward ASCII commands or MODBUS®. All three types of communications interfaces can be installed and active simultaneously.

LabVIEW™ Driver
The Platinum LabVIEW™ driver is the National Instrument device driver for communicating with Omega Platinum Controllers via Modbus RTU/ASCII and Modbus TCP protocols. The driver allows easy access to the internal data, configuration settings, and operating functions of the Platinum product family.

The LabVIEW™ instrument driver reduces the application development time and simplifies instrument control. With the Platinum LabVIEW driver, customers can quickly communicate with the instrument and develop robust test applications and software.

DasyLab
Support for the easy-to-use DasyLab software solves complex data acquisition and control problems by allowing you to work with flowcharts directly on your PC screen. The high input accuracy, advanced process control, extended sequencing capability and flexible output options of a Platinum controller may be easily integrated with the rich set of function modules provide by the DasyLab software. The DasyLab software may be integrated thru the Platinum serial, Ethernet or USB connections.

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.
Date published: 2017-10-27
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.
Date published: 2020-11-25
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
Date published: 2016-02-11
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.

CN16DPT-145. There is limited info on the retransmit function. I'd like to retransmit measured temperature from a thermocouple. How does the scaling work for retransmit?

Asked by: NIST
To set the Analog output range on the Platinum Controllers you need to select the RNGE in the PROG menu then scale it in the RtRN parameter in the PROG menu in your case for ANG1 as well. Please call the temperature department if you need detailed assistance.

When I turn the power on to the Omega USB Platinum Temperature controller, the Omega display reads "oPER". What does this mean?

Asked by: Richie_GDS
Thank you for your inquiry! The "oPER" text on the display stands for Operating Mode and is found in the Level 1 Menu. For more information on how to navigate through various menus, please see page 16 of the Platinum Series Controller User Guide Manual (M5451).

All the controller have 2 or 3 outputs, but we can only control one load at a time due to having only one input. Then what is the purpose of having three different or same outputs?

Asked by: Maxy
Hi Maria, Thank you for the inquiry. Second output is often used for cooling. It can also be used for second heater ( or other load) to act as back up to a primary heater. There is a second PID group and control offset to provide for these options. Best regards OMEGA

Hi there, I am interested in the CN32PT-440. Are the isolated DC pulse outputs isolated from the AC power input or the sensor input or both? I am assuming isolated means the grounds are floating compared to each other?

Asked by: Madt
Hi Madt, Thank you for the inquiry. On this model the DC pulse output signals are isolated from the AC line not the input signal. Isolation spec is detailed in section 9.5 on the manual; https://assets.omega.com/manuals/M5451.pdf Best regards Omega

I want to but a controller for heating only from 100 to 500 degree Celsius. Which option is better for this? Output with Mechanical relay or Solid State Relay?

Asked by: Maxy
Hi Maxy- If maintaining temp for long duration is your end goal then SSR will be best. Not only will the control around the set point be more precise but SSR also has extended life cycle over mechanical relay. Be sure to check the specs of the heater on power required as solid state relays and mechanical relays outputs vary.

I want to drive a 24Vdc 3port/2way solenoid air valve. What output option do I select? I see there is a DC power supply option will that be needed?

Asked by: JulieC
Hi Julie, Thank you for the inquiry. For your device the best option to use is the mechanical relay. You will need a power source suitable for your relay coil. The internal excitation is limited to 25 mA @ 24 VDC. Best regards Omega

Hi, I installed a CN32PT-305-DC in an aluminium case and the thermocouple reading is very sensible to the internal controller’s temperature ans doesn’t represent the true temperature at the sensor. How can I fix this problem ? Thanks

Asked by: Sylvain
Hi Sylvain, Thank you for the inquiry. Suggest to ensure that you have thermocouple connectors and thermocouple extension wire inside the enclosure. Double check the thermocouple wire polarity inside the enclosure. Best regards OMEGA

How do I change the output on a CN32PT-224-C24 to analog 0-5VDC. The Platinum GUI seems to resisto me making the change is there some king of unlock that needs to be done?

Asked by: Mark Morin
Hi Mark, Thank you for the inquiry. Unfortunately this controller does not have analog output. Similar controller with analog output is CN32PT-145-C24 Best regards OMEGA
