DVP04DA-H2 is an analog signal output module released by Delta, which supports voltage output or current output. The voltage output range is 0V ~ +10VDC with a resolution of 2.5mV; the current output range is 0mA ~ 20mA with a resolution of 5μA.
The Delta DVP04DA-H2 is a 4‑channel analog signal output module that can deliver voltage (0‑10 V) or current (0‑20 mA) signals based on 12‑bit digital inputs. It connects to a PLC via RS‑485 and supports both Modbus ASCII and RTU modes.
This manual provides safety instructions, wiring diagrams, functional specifications, register maps, and example programs for setting output modes, adjusting gain/offset, and handling error conditions. It also details power requirements, environmental limits, and LED indicators for status monitoring. This manual is written in Chinese.
