Description

The Industry Leading Omega's 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, models are available with single and dual 4 digit displays or single 6 digit display.

Each unit allows the user to select the input type from 9 thermocouple type, Pt RTDs, thermistors, DC voltage, or 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 and additional unique features make the PLATINUM Series "The Most Powerful" product in its class. Some of these additional standard features are: remote setpoint for cascaded control set-ups, high-high/low-low alarm functionality, external latch reset, external ramp and soak program initiation, combination heat/cool control mode, configuration save and transfer, and configuration password protection.

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.

*If you have the previous firmware version 1.3.0.25 installed, please upgrade it to the latest.
