This document is the user manual (V6.12) for the DAM-3000 Data Acquisition Modules. It describes the main indicators and features of the module, including input types, thermocouple types, channel inputs, sampling frequency, resolution, accuracy, etc. It also provides information such as wiring diagrams, structure diagrams, and code configuration tables.
This manual describes the DAM-3039F data acquisition module, which offers up to six differential channels, two single‑ended channels, and optional eight‑channel differential mode. The module features 16‑bit resolution, 0.1% accuracy, and a 20 MΩ input impedance, with low temperature drift and high isolation voltage.
Power is supplied at 24 VDC with a consumption of 0.8 W. The device supports RS‑485 communication, multiple baud rates (1200‑115200 bps), and a variety of input ranges from 15 mV to 2.5 V. Terminal assignments and wiring diagrams are provided for proper installation and operation. This manual is written in Chinese.
