The Delta DVP30EX200R is a DVP Series EX2 Series Temperature/Analog PLC, a base unit with 3 inputs and 1 output, powered by 100 ~ 240VAC. This is the relay output variant of the EX2 line, designed for applications requiring temperature or analog signal processing alongside discrete control.
The 3 inputs and single relay output suit it for a compact temperature or analog control node — think a single-zone oven or a small process loop where you need a few analog channels and one discrete actuator. The 100 ~ 240VAC supply means it drops into a standard control panel without a separate DC power supply for the CPU.
Peer Comparison
The closest sibling is the DVP30EX200T, which shares the same 30-point form factor and EX2 series designation but uses transistor (sink/source) outputs instead of relay. If your load is a small contactor or valve that needs dry-contact switching, the R variant is the right pick; if you are driving a high-speed counter or a solid-state load, the T variant would be the one.
