The PXR4NAY1-MW000-X is a digital temperature controller from Fuji Electric's PXR4 series, accepting a Pt100 3-wire resistance bulb input in °C. It provides two relay contact outputs — one main, one secondary — and includes one alarm point. The 48 × 48 mm front panel with screw terminals fits standard panel cutouts. Lifecycle stage is current, so this is a production-active part for new builds and spares holding alike.
Input and output configuration
Input is fixed to a Pt100 3-wire resistance bulb, which gives good lead-length compensation for remote sensing — common in oven, kiln, and process-heat applications. Control output 1 and control output 2 are both relay contact outputs, so the controller can drive a contactor or SSR directly on the main output and use the second relay for an alarm or secondary heat/cool stage. The 'Alarm 1 point' option is built into this code, so no external alarm module needed.
