The Delta DVP20EH00R3 is a Main Processing Unit (Base Unit) in the DVP Series, part of the EH3 Series line. It packs 20 I/O points into a compact base-unit form factor — enough for a small machine cell or a distributed I/O drop without an expansion rack.
The DVP20EH00R3 carries 20 I/O points on board, which means it can handle a mix of digital inputs and relay outputs for basic control sequences — think conveyor interlocks, simple pick-and-place cycles, or pump sequencing. As a base unit, it includes the CPU, power supply, and I/O in one package, so no separate backplane or processor module is needed.
