This Instruction Sheet only provides descriptions for electrical specifications, general specifications, installation & wiring. Other detail infromation about programming and intructions, please see “DVP-PLC Application Manual: Programming”. For more information about the optional peripherals, please see individual product instuction sheet or “DVP-PLC Application Manual: Special I/O Modules”.
This manual provides the electrical specifications, installation methods, and wiring diagrams for the DVP‑EH3 series programmable logic controller. It explains how to mount the unit in an enclosure, connect power and I/O modules, and ensure proper grounding and protection against electromagnetic interference.
Safety precautions, battery‑low indicator behavior, and detailed wiring instructions for input, output, and differential modules are also included, helping technicians set up the PLC correctly and maintain reliable operation.
