DDMF2 8DA User Manual introduces the basic functions, features, parameters, purposes and other information of the product.
This manual describes the DDMF2-8DA analog output module, an 8‑channel, 12‑bit device that communicates via MODBUS RTU over RS‑485. It outlines the module's main features, electrical specifications, and wiring details, and explains how to integrate it with PLC, DCS, or PCS control systems.
The document includes instructions for installing the module, configuring communication parameters (baud rate, data bits, parity, stop bits), setting output ranges, and using the provided JTDDMX software to adjust parameters. It also covers register mapping (40001‑40008) for reading and writing analog values and provides troubleshooting tips such as CRC verification. This manual is written in Chinese.
