Description

From Jan 1st 2018, CNPT-DEMO models have been discontinued. As a possible substitute for laboratory application, please check out the CS8DPT for details.

The PLATINUM Demo & Training unit provides a PID control simulator that is fully integrated temperature control system suitable as a platform to investigate the use of closed loop (PID) and simple on/ off temperature control in both heating and cooling applications.

The demo unit includes a CN8DPT-144-C24-EIP-DC controller, powered by 12 Vdc, 2A universal AC to DC adaptor. It has a thermoelectric heating/ cooling element capable of 5 to 50°C setpoint and a Type K thermocouple for temperature readings. The unit comes with panel mounted USB and ethernet connectivity, an alarm indicator, a 4 to 20 mA remote set-point potentiometer, a pushbutton digital input, and an aluminum plate allowing the user to feel the temperature response.

A powerful 32-bit, 120 Mhz ARM processor provides an full PID control process with auto-tuning and a fuzzy logic based adaptive control algorithm that automatically adjusts and optimizes the control loop parameters based on external environmental or control system deviations.

A comprehensive set of alarm functions may be used to trigger output signals and/or modify the display colors for above, below, in-band and out-of-band conditions. Physical outputs may be assigned to Alarm, PID, ON-OFF control or auxiliary output functions.

An advance 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.

The CN8DPT features a large, 3-color (RED, GREEN, and AMBER) programmable LED display with the capability to change color and/or change the state of designated outputs when an alarm is triggered.

An embedded ethernet connection allows the unit 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. The USB connection allows connecting the unit to the Windows based PLATINUM configurator software for configuration and monitoring as well as supporting USB based ‘thumb drives’ for directly transferring configuration data.

The PLATINUM Series family may be fully configured using an integrated 4 button keypad using a structured menu system, optimized to navigate to only those parameters applicable to the selected configuration. The PLATINUM configurator software may be connected thru the USB, serial or ethernet port to provide a Windows based PC application to provide a pointand- click configuration interface, performance charting and logging and the ability to load and save configuration files compatible to the PLATINUM USB file transfer protocol.
