PXR4/PXR5/PXR7/PXR9 Advanced Self-Tuning Temperature & Process Controller
Brand: Fuji Electric Co, LtdIn 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.
Features- PID with fuzzy control of self-tuning
- 16 A /soak segments
- Large LED display
- Digital input
- Auto-tune
- Timer function
- Heater burnout alarm
- Replaces most other controllers in market
- Excellent for after-market support
