What this PID controller covers
The PXG4CYY1-0VYA1 is a PID controller from the PXG series, configurable across 1/16, 1/8 and 1/4 DIN panel cutouts — meaning the same part number can fill different panel slots depending on the adapter or mounting kit used. It carries many input/output points and sophisticated control functions, suited for temperature, pressure, or flow loops in a process panel.
