Delta DVP28SS211R — 28-point slim PLC, current production
The Delta DVP28SS211R is a 28-point slim PLC from the DVP-S Series, running on a 24VDC supply. It carries 16 inputs and 12 outputs, sized for a compact machine-control panel where every DIN-rail millimeter counts.
16 inputs and 12 outputs give you a 28-point total. That covers a small standalone machine — say a pick-and-place station with a few sensors and pneumatic valves — without needing an expansion module on the first pass. The 24VDC power rail is standard for the DVP-S family, so it shares the same backplane supply as the rest of the series. No separate 5V or 24VAC tap needed.
Peer comparison — DVP28SA211T vs DVP28SS211R
The DVP28SA211T is the closest functional peer — same 16 inputs, 12 outputs, 24VDC supply, and same Slim DVP-S Series footprint. The difference is the output type: the SS211R uses relay outputs, while the SA211T uses transistor (sink) outputs. If your downstream loads are solenoids or contactors that need dry-contact isolation, the SS211R fits. If you need high-speed pulse trains for a stepper or servo drive, the SA211T is the pick.
