PLC I/O count and power supply
The Delta DVP28SA211R is a slim-form PLC from the DVP-S Series, carrying 16 inputs and 12 outputs on a 24 VDC supply. That I/O count — 16 in, 12 out — is the main thing to check against your BOM: if your panel needs exactly that split, this unit fits without reallocating spare channels. The 24 VDC rail is common across the DVP-S family, so if you're already running that bus, no extra power supply module needed.
