The PXF4ABA2-JBKA1: The 1/16 DIN (48 x 48mm) form factor is the standard panel cutout for compact controllers. It fits the same 45 x 45mm panel hole as every other 1/16 DIN unit, so a swap-in replacement for an existing controller of this size is mechanically straightforward — no panel rework needed.
Temperature and process controllers of this class are deployed in panel-mounted control cabinets for industrial heating processes — plastic injection molding, packaging seal bars, heat-treat furnaces, and laboratory ovens. The self-tuning feature reduces commissioning time: the controller learns the process dynamics on startup and sets its own PID gains, so a technician can get the loop running without a tuning session.
