The Delta DVP40EH00R3 is the main processing unit (base unit) for the DVP Series, specifically the EH3 Series PLC, packing 40 I/O points into a single chassis. This is the brain of a mid-size machine control system, handling logic, sequencing, and basic motion tasks without needing a separate rack or backplane — everything lives on this one base unit.
What the 40 I/O Points Mean for Your Panel
Forty I/O points on one base unit means you can handle a small conveyor section, a packaging cell, or a pump skid's worth of sensors and actuators without adding expansion modules. The R in the model code denotes relay outputs on the transistor-versus-relay choice — relay outputs handle inductive loads like contactor coils and small motors directly, which is a solid fit for the grease-and-grit environment where a lube route technician might bury a few before breakfast. No delicate transistor stage to blow out when a solenoid kicks back.
