They come in several sizes – 1/32 DIN, 1/16 DIN, 1/8 DIN and 1/4 DIN. These controllers have all the standard features that you expect from Fuji Electric’s superior controllers, and more. 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 setpoint, RS485 communications, analog retransmission, digital input, timer function, heater burnout alarm and 24V AC/DC supply voltage.
One of the most impressive features is the large LED display. The faceplate, designed for NEMA 4X (IP66 equivalent) is watertight and corrosion-resistant. The easy-to-use 3-button keypad allows for programming similar to the popular PXW controller. The screw-terminal on the back further reduces the cost by eliminating the need for sockets. The PXR3 can be DIN-rail mounted with the optional adapter.
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
