What this controller is
The Fuji Electric PXF5ACR2-JBTA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
The 1/8 DIN form factor (48 x 96mm panel cutout) makes it a drop-in replacement for existing DIN-rail or panel-mount temperature controllers in the same footprint. The self-tuning algorithm handles PID autotuning on startup, which saves commissioning time on multi-zone ovens or environmental chambers.
