The Delta DVP16EH00T3 is a Main Processing Unit (Base Unit) in the DVP Series, carrying 16 I/O points on a single compact chassis. It is the controller core for a small-to-medium machine cell — you build the I/O map around these 16 points, then expand via the extension bus if the application needs more.
Peer comparison — what the suffix tells you
The DVP16EH00T3 shares its 16-point base-unit footprint with the DVP16EH00T2, DVP16EH00R2, and DVP16EH00R3. The 'T' in the suffix indicates transistor outputs (sinking/sourcing DC loads), while 'R' denotes relay outputs. The digit (2 vs 3) signals the generation within the EH series — the T3 is the later revision. If your panel was laid out for a DVP16EH00T2, the T3 drops into the same DIN-rail slot and wiring scheme without rewiring, though you should verify the output current rating matches your load.
