Panel fit and field service
The PXF4APE2-FVMA1: Standard 1/16 DIN cutout (45 x 45 mm) — drops into any existing panel hole that size. The 48 x 48 mm bezel is the same footprint as every other 1/16 DIN controller on the market, so if you're swapping out a failed Omron E5CC or Yokogawa UT35, the cutout matches. No DIN-rail mounting; it's a panel-mount controller with a clamp bracket. Wiring is via a rear terminal block — pull the old unit, land the same wires on the same terminal numbers, and you're back in business. No special tools needed beyond a small screwdriver.
