The DVP04PT-H2 is an open‑type temperature‑measurement module that accepts up to four resistance temperature detectors (PT100, PT1000, NI100, NI1000) and converts their signals to 16‑bit digital values. It can be integrated into a PLC system via RS‑485 communication.
This guide provides the mechanical dimensions, terminal layout, wiring recommendations, electrical specifications, control register descriptions, and communication settings needed to install and configure the module safely and reliably.

| Resolution | 16‑bit (0.1 °C / 0.1 °F) |
| Output impedance | ≤ 0.50 Ω |
| Overall accuracy | ±0.6 % full scale (0 – 55 °C, 32 – 131 °F) |
| Response time | 400 ms × number of channels |
| Communication baud rates | 4,800 – 115,200 bps (selectable) |
It can receive four points of resistance temperature detectors (PT100, PT1000, NI100, and NI1000).
Terminals should be tightened to a torque of 1.95 kg‑cm (1.7 in‑lb).
The module uses RS‑485 communication with selectable baud rates of 4,800, 9,600, 19,200, 36,400, 57,600, or 115,200 bps.
