The Fuji Electric PXF5ACA2-FVVA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed.
The 1/8 DIN (48 x 96mm) form factor fits the standard panel cutout for temperature controllers, so it drops into an existing hole without adapter plates. The self-tuning algorithm handles PID autotune on startup, which saves a commissioning engineer from manually tweaking gains for most process loops.
