The PXF4APC2-MBKA1 is a self-tuning 1/16 DIN (48 x 48 mm) compact temperature and process controller with a 50 ms sampling speed. It's a current-production part, so you can spec it into a new panel without worrying about last-time-buy windows.
Deployment and integration
The 1/16 DIN (48 x 48 mm) form factor fits the standard panel cutout. Mount it in a control cabinet alongside other DIN-sized instruments; the compact footprint leaves room for additional modules in a multi-zone temperature setup.
