The PXR3 is Fuji Electric's powerful self-tuning 1/32 DIN temperature/process controller with low-cost communications option. The new PXR3 controller is packed with features, to meet a wide variety of needs in the process control industry. Low-cost options include RS485 communications, analog retransmission, digital input, timer function, dual outputs, programmable alarms, and 24 VAC/DC power supply.

One of the most impressive features is the large LED display — larger than most other 1/32 DIN controllers on the market. The faceplate is watertight and corrosion-resistant. The easy-to-use 3-button keypad allows for programming.

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 PXR3 accepts temperature and process inputs, and offers two control outputs and two programmable alarms.
