CNPT-Series

The DwyerOmega CNPT-Series delivers a universal high performance controller built for accuracy, flexibility, and ease of use in demanding process control environments. Available in compact DIN sizes (1/32, 1/16, 1/8), this universal high performance controller accepts a wide variety of input types—including thermocouples, RTDs, thermistors, voltage, current, strain, and bridge inputs—making it ideal for labs, OEM systems, and industrial automation where diverse measurement sources are involved.

Engineered for precision, the CNPT handles up to 20 samples/second and offers selectable high accuracy across its inputs. It features multiple programmable outputs—alarms, relays, analog retransmission—and includes advanced PID control with fuzzy logic for stable, responsive control over temperature, pressure, flow, or other process variables. With dual displays, USB interface, and optional Ethernet / Modbus connectivity, this controller supports modern monitoring and integration needs without sacrificing performance.

Backed by DwyerOmega reputation for reliable design, compliance, and support, the CNPT-Series universal high performance controller gives operators tighter process control, reduced downtime, and adaptability to evolving system requirements. Whether replacing older controllers or designing new control systems, CNPT delivers both power and precision.

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.
