The DVP80EH00T3 is a Delta DVP Series Main Processing Unit (Base Unit) with 80 I/O points — a standard PLC for the EH2/EH3 line. That 80-point count means it handles a medium-sized machine or process cell without needing an expansion rack for the first pass of I/O. Current lifecycle stage, so it's still a valid BOM line for new builds, not a scavenger hunt.
Compared to the DVP80EH00T2, the T3 is its direct successor within the same 80-point base-unit footprint. Both are Main Processing Units in the DVP Series, so the panel layout and wiring harness carry over — no re-termination needed. The T3 brings whatever processor or firmware updates Delta rolled into the EH3 generation over the EH2.
