Self-tuning 1/16 DIN temperature and process controller


The Model PXR4 controller features a large LED display that is reportedly larger than in any other 116 DIN controller on the market. Options include RS485 communications, digital input, timer function, heater burnout alarm, dual outputs, and programmable alarms. The faceplate is watertight and corrosion resistant. A screw terminal on the back is said to eliminate the need for sockets.

The controller comes with a self-tuning feature in addition to autotuning and fuzzy logic control capabilities. Self-tuning allows for retuning the controller under certain conditions without reverting to autotuning. The standard ramp/soak feature has two patterns that can be linked to create a 16-step profile. The controller accepts temperature and process inputs with two control outputs and two programmable alarms. The RS485 option uses the industry-standard Modbus protocol and enables remote monitoring of up to 31 controllers at a time.
