50 ms sampling in a 1/4 DIN cutout
The PXF9ABP2-FBHA1: The 1/4 DIN form factor fits the standard 92 x 92 mm panel cutout; the compact depth leaves room behind the gland plate for relay and power wiring without crowding the backplane.
Current lifecycle — no LTB window to chase
The self-tuning algorithm and 50 ms sample rate are the differentiators against older PXF-series siblings — confirm the control loop requirements before substituting.
What the self-tuning and 50 ms sample rate mean on the line
Self-tuning means the controller auto-calculates PID parameters during the first heat-up cycle — no manual Ziegler-Nichols tuning for a commissioning tech. The 50 ms sampling period updates the output every half cycle at 50 Hz mains, so the controller sees a temperature change within one power-line cycle and can respond before the next zero-cross. For a process controller, the sample rate sets the minimum detectable event width. 50 ms catches fast-responding loads like infrared heaters or small-zone electric furnaces where a 1-second loop would overshoot. The self-tuning algorithm also adapts to load changes (batch size, material change) without a re-tune call.
