The Delta DVP04AD-H3 is a 4-point analog input extension module in the DVP Series, designed to add analog measurement capability to a DVP PLC system. The 04 input points handle standard analog signals — voltage or current — giving the controller visibility into process variables like pressure, level, or flow from field transmitters.
The DVP04AD-H3 carries a current lifecycle stage, meaning Delta continues to manufacture and support this order code. For a critical-spare buyer holding a DVP-based line, this module is still the direct production part — no forced migration yet.
As a DVP Series extension module, the DVP04AD-H3 connects to the expansion bus of a compatible DVP CPU. The 04-point count means it occupies one slot on the rail and adds four analog input channels. No rewiring is required when swapping between the DVP04AD-H3 and its predecessor DVP04AD-H2 — the terminal assignment and bus connector are identical, so it drops into a panel originally specified around the H2 variant without re-termination.
