In addition to auto-tuning and fuzzy control, it now comes with self-tuning - an innovation in the control field. 
It 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 needs in the process industries.
 Low-cost options include dual outputs, programmable alarms, remote set point, RS-485 communications, Analog retransmission, digital input, timer function, heater burnout alarm and 24 Vac/dc supply voltage.
