PXF9AEY2-1W100 is a Micro-Controller X, revision 2, with one current output (Control Output 1 = E) and no second output (Control Output 2 = Y). Alarm output is a single point (1 = 1 points). The front panel measures 9.6 cm x 9.6 cm; overall dimensions are 5.8 cm deep x 9.6 cm wide x 9.6 cm high. That's a square panel cutout — fits a standard 96 mm x 96 mm panel opening common in process controllers.
The current output (Control Output 1 = E) means the controller drives a loop-powered 4-20 mA or similar analog signal — typical for a process variable like pressure or temperature sent to a PLC analog input or a remote I/O slice. The single-point alarm output gives one dry-contact or solid-state alarm relay for high/low trip, not multiple setpoints. Revision code 2 means a hardware or firmware iteration; if you're replacing a revision 1 unit, check the control output mapping and alarm logic — the panel wiring stays the same, but the parameter default may shift.
