PID with fuzzy logic and self tuning
  • 1-6 Ramp/soak segments
  • Large LED display
  • Auto-tuning
  • RTD, thermocouple, mA, V inputs

The PXR series comes in several sizes - 1/16 DIN, 1/8 DIN and 1/4 DIN. Besides the standard features including auto-tuning and fuzzy logic, they also come with self-tuning. This innovative feature automatically retunes the controller under certain conditions without the need to revert to auto-tuning.
The standard 8-segment ramp/soak feature has been expanded to include two patterns that can be linked to create a 16 step profile. The PXR accepts temperature and process inputs and offers a choice of three kinds of outputs to meet a wide variety of process requirements. Low cost options include dual outputs, programmable alarms, remote setpoint, RS485 communications, analog retransmission, digital input, timer function, heater burnout alarm and 24V AC/DC supply voltage. Other features include a large LED display and a NEMA 4X (IP66 equivalent) faceplate that is watertight and corrosion resistant. The easy to use 3 button keypad allows easy programming. The rear screw terminal makes connection easy and eliminates the cost of extra sockets.

Remote monitoring of up to 31 controllers at a time is possible with the RS485 option that uses the industry standard Modbus protocol. The communications option comes with our free Windows- based software PXR-LITE which allows programming the controller from the PC and viewing real- time data and a trend graph while logging data into a text file.
