The PXF5ACA2-JBHA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50 ms sampling speed. This places it in the fast-loop category for thermal processes — injection molding barrel zones, packaging seal bars, or extrusion barrel heating — where overshoot and settling time matter. The 50 ms update means it can respond to a thermocouple step change within a few cycles, not the half-second or longer typical of general-purpose PID units.
The 1/8 DIN (48 x 96mm) panel cutout is the standard single-loop controller footprint — fits a 45 x 92 mm panel hole with the gasket. The 50 ms sampling speed is the rate at which the controller reads the input and updates the output; for a plastic injection molding barrel zone with a 2-second time constant, that is fast enough to catch a 5 °C overshoot before it settles. Self-tuning means the controller automatically calculates PID parameters on the first heat-up, saving commissioning time on a new tool or retune.
Temperature and process controllers of this class mount into a panel cutout and connect to a thermocouple or RTD input, a control output (relay, SSR drive, or analog), and an alarm relay. Typical deployment is on a machine control panel for a packaging sealer, an injection molder, an oven, or a heat-treat furnace. The compact 1/8 DIN size leaves panel space for additional I/O or a second loop.
