The PXF5ACA2-MVGA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed.
The 1/8 DIN footprint (48 x 96 mm) is a standard panel cutout — drops into the same hole as any other 1/8 DIN controller, so no panel rework if you're swapping out an older unit. Self-tuning means the PID loop auto-adjusts on startup; you don't need to babysit it with manual tuning constants unless the process demands it.
