PXF4ABA2-FBSA1 Temperature Controller, 1/16 DIN, 50ms Sampli

The Fuji Electric PXF4ABA2-FBSA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That sampling rate means it updates the control output every 50 milliseconds — fast enough for most thermal loops in packaging, plastics, and HVAC, but not for sub-cycle power control. The self-tuning algorithm adjusts PID parameters on startup, so you can drop it into a replacement slot without re-tuning from scratch.
