PLC Unit for 28-I/O Control
The Delta DVP28SV11R is an S-TYPE Main Processing Unit from the DVP-SV2 High Performance Slim PLC series, delivering 28 I/O points in a compact footprint. The DC input is designated H TYPE, and the output is relay-based, making it a fit for discrete control applications where isolation per channel matters — think solenoid banks, contactor coils, or signal interlocking on a conveyor line.
I/O Count and Output Type
With 28 points total, this unit splits between inputs and outputs in a fixed configuration typical of the DVP-SV2 slim form factor. The relay output side handles AC and DC loads up to the rated contact capacity, which means you can drive pilot devices or small contactors without an interposing relay panel. The H TYPE DC input is sink/source configurable, matching both NPN and PNP sensor families common on material-handling lines.
The slim DVP-SV2 housing clips onto a DIN rail, freeing panel width for additional I/O slices or a power supply. The 28-point density suits a small machine cell or a remote I/O station where a full-rack PLC would be overkill. Mount close to the field wiring — the relay outputs benefit from short runs to inductive loads to keep flyback noise off the backplane.
