Temperature Controller - Pxr Series
Description: The latest temperature controller series from Fuji Electric, the PXR has new and improved features. This 1/16 DIN temperature controller includes an LED display that is 1.6 times larger than other previous models with dust-proof front display and operational section that is waterproof and conforms to NEMA4X (IP66). The PXR series controllers come in 24 x 48 mm, 48 x 48 mm, 48 x 96 mm and 96 x 96 mm sizes. Both auto-tuning and the more advanced, self-tuning functions calculate optimum PID parameters. Fuzzy control is a standard feature suppressing overshoot without lengthy start-up time and improving the response to external disturbances by quickly reverting to set points. A standard feature included in the PXR is the 16-segment ramp/soak and Menu driven Auto/Manual mode of operation. The digital input option that can be added to the PXR, allows the operator to remotely change between two set points, start/stop the control action, start/reset the ramp/soak, start stop the auto tuning, cancel the alarm latch, or start the incorporated timer. The PXR series controller offers additional options that include timer function, heating/cooling control, heater burnout alarm, and the free, standard 16-segment ramp/soak function feature. Relay, SSR driver and 4-20 mA outputs may be chosen. The PXR series controllers, accepts temperature and process inputs, and offers two control output alarms and two programmable alarms. Daisy-chaining up to 31 controllers on an RS-485 network is an option with the PXR. Using a PC, the operator is then able to monitor all 31 controllers via the industry standard MODBUS communications protocol.
