The PXR3-AAY2-4VRA1: The 1/32 DIN form factor (48 x 24 mm panel cutout) fits tight panel layouts where space is at a premium — common in multi-zone oven control or packaging machinery with several zones per cabinet. Self-tuning simplifies commissioning: the controller learns the thermal response of the load and sets PID parameters automatically, reducing manual loop tuning time.
The 16 ramp/soak segments allow programming of multi-step thermal profiles — useful for soldering, curing, or heat-treating processes that require controlled temperature ramps and soak holds. Self-tuning adapts to the process dynamics, so the controller works across different oven or heater sizes without manual PID re-entry.
