The DVP-04AD-SL is a 4‑channel analog input module for Delta DVP series PLCs. It converts 16‑bit digital data from the PLC into four analog signals, supporting both voltage (‑10 V to +10 V) and current (‑20 mA to +20 mA) inputs.
This guide covers safety and installation precautions, mechanical dimensions, wiring diagrams, electrical specifications, control register descriptions, A/D conversion curve adjustments, error status information, and history command usage. It also provides recommended torque values and cable types for reliable operation.
| Voltage input range | -10 V ~ +10 VDC |
|---|---|
| Current input range | -20 mA ~ +20 mA |
| Power supply voltage | 24 VDC (-15% ~ +20%) |
| Analog input channels | 4 |
| Resolution | 16 bits (15 bits effective) |
| Input impedance | < 0.5 Ω |
| Overall accuracy | ±0.3 % full scale (25 °C) |
| Response time per channel | 250 µs |
| Isolation voltage | 500 VDC between analog, digital, and ground |
The tightening torque for the I/O terminal block is 1.95 kg‑cm (1.7 in‑lbs).
The input mode is set via the channel’s control register (CHx) using values such as 0 for voltage ±10 V, 1 for current ±20 mA, etc.
Use 60 °C/75 °C copper conductors and shielded cable for analog and power wiring.
The module operates from 0 °C to 55 °C with 50 %–95 % humidity and pollution degree 2.
