The Fuji Electric PXF5ACR2-JBCA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed.
The 50 ms sampling speed is a genuine upgrade over the 100 ms typical of earlier PXG-series controllers, so you can tighten loop response on an existing thermocouple or RTD input without rewiring the sensor.
