DVP04AD-E2 module is a module of Delta DVP series programmable logic controller. It can receive 4 analog input signals and convert them into 16-bit digital signals. Through the port configuration, you can select voltage input or current input. Through FROM/TO instructions, you can access the data in the module, or you can directly read the average value of channels by using MOV instruction (Please refer to allocation of special registers D9900 ~ D9999).
The DVP04AD-E2 is a 4‑channel analog input module for Delta PLC systems. It converts external voltage or current signals into 16‑bit digital data and supports both voltage (±10 V, ±5 V) and current (±20 mA) input ranges. The module features optical‑coupler isolation, configurable input modes, and built‑in self‑diagnosis.
The manual covers electrical specifications, wiring diagrams, I/O terminal layout, register maps, and configuration procedures. It explains how to use FROM/TO instructions and special registers D9900‑D9999 to read average or present values, adjust offset and gain, and enable limit detection. Installation guidelines emphasize proper grounding, shielding, and environmental conditions.
