The Fuji Electric PXR3-ACC2-4B0A1 is a 1/32 DIN panel-mount temperature and process controller that self-tunes its PID loop and provides 16 ramp/soak segments for multi-step thermal profiles — think oven cure cycles, autoclave ramps, or batch reactor sequences where the setpoint needs to follow a timed temperature curve rather than hold a single target.
What the 16 ramp/soak segments mean for your process
Sixteen ramp/soak segments let the controller execute complex thermal recipes — a typical use is a four-ramp, four-soak profile for epoxy cure or metal heat-treating — without an external PLC or sequencer. Each segment defines a ramp rate (time to target temperature) and a soak duration (hold at that temperature), and the controller advances through the profile automatically. The self-tuning function measures the process response and sets the PID gains automatically, which saves commissioning time on ovens, furnaces, and environmental chambers where manual tuning would be trial-and-error.
The 1/32 DIN form factor (48 × 24 mm panel cutout) fits standard DIN-rail adapter frames or panel cutouts alongside other miniature controllers. It is sized for equipment where panel space is tight — lab ovens, packaging machines, small autoclaves — and its shallow depth leaves room behind the panel for wiring and optional output modules.
