The PXF4AEU2-4VYA1 is a PXF SERIES 1/16 DIN (48x48mm) temperature and process controller with a 50ms sampling speed and self-tuning capability. It accepts a universal input signal — thermocouple or VDC — with backwards-compatible wiring to the PXR/W/Z families, making it a direct drop-in for panel retrofits that need current output control (4-20 mA loop, typically) and a standard 100-240V AC, 50/60Hz power supply.
Panel fit and programming
Socket-type 1/16 DIN body (48x48mm front panel cutout) — mounts into the standard panel opening without adapter rings. Programming is set to North American Code, which affects the parameter map and alarm logic conventions; if your BOM specifies a different regional variant, the parameter list differs at the menu level.
Input and output reality
Universal input covers T/C and VDC types, and the wiring pinout matches the earlier PXR/W/Z series — so if you are swapping a failed PXR on a running line, the termination stays the same. The control output is current (analog 4-20 mA, by convention for this class), which drives a SCR or IGBT firing module directly, rather than a relay or SSR drive. The 50ms sampling rate is fast enough for thermal processes (ovens, extruder zones, packaging seal bars) but not for sub-cycle power control.
