Panel fit and field wiring
The 1/4 DIN cutout (96 x 96 mm) is the standard panel-mount footprint for standalone process controllers — same hole as an old Honeywell UDC or a Eurotherm 2400 series. The PXF9ACR2-0VVA1 slides into the cutout and clamps with the included bracket; no DIN rail adapter needed. Terminal blocks are pluggable, so a swap-out means pulling the connector block, not re-terminating each wire.
