Panel fit and deployment
The PXF4ACY2-FBMA1: The 1/16 DIN (48 x 48 mm) cutout is the standard panel-mount footprint for compact controllers. It fits the same hole as dozens of other makes, so swapping into an existing panel requires no rework of the cutout. The self-tuning algorithm handles PID autotune on startup — useful when the process loop has unknown thermal characteristics and you don't want to sit there with a stopwatch.
