50 ms sampling — what it means for your loop
The PXF9AEC2-FBCA1 samples the process variable every 50 ms. For a temperature loop on a 4-zone injection mold barrel, that update rate catches the thermal lag in the nozzle and front zone before the deviation propagates — you hold the zone tighter than a 100 ms controller on the same thermocouple. Self-tuning means the controller auto-calculates PID gains during the first heat-up cycle. On a new tool, that saves the hour of manual Ziegler-Nichols tuning per zone — the controller converges on the gain setpoint while the barrel reaches soak.
1/4 DIN panel fit — 96 x 96 mm cutout
The 1/4 DIN (96 x 96 mm) footprint matches the standard panel cutout for temperature controllers in this class. The depth behind the panel is compact enough for a shallow enclosure — no need to overspec the cabinet depth for a single controller. Mounts in the standard DIN-rail adapter or direct panel cutout. The 96 mm width leaves room for a 24 VDC power supply and a solid-state relay on the same sub-panel without crowding the gland plate.
