CMDF1-8AD analog input acquisition module is used for programmable controllers (PLC for short), DCS, PCS, and computer system analog input expansion. It supports Mitsubishi LINK RS-485 communication mode and supports multiple configuration software. The analog input and communication circuit are isolated, and the 8 input channels can be cyclically displayed in voltage or current.
This manual describes the main purpose, features and technical parameters of the CMDF1‑8AD RS‑485 LINK module, a communication interface for PLC and DCS systems. It includes power requirements, communication settings, input signal types and physical dimensions.
The document also explains how to configure the module using the JTconfig software, how to set channel parameters, and how to perform signal calibration and troubleshooting steps. This manual is written in Chinese.

The module provides eight independent input channels that can accept 0‑20 mA or 0‑10 V signals.
It operates from a DC supply of 9 V to 30 V.
Parameters are set using the JTconfig configuration utility.
The RS‑485 link can run at baud rates from 600 bps up to 115200 bps.
