DDMF1-16DO is a switch output expansion module produced by Jietong Technology Co., Ltd. The main features include Mitsubishi LINK RS-485 communication mode, 16-bit transistor switch leakage output, 16 output status LED indication, 300-115.2Kbps optional, receive, send indication status, switch output circuit and communication circuit electrical isolation and power supply polarity protection.
The DDMF1‑16DO is a 16‑channel transistor‑leakage switch output module designed for PLC, DCS, PCS, and computer‑based control and alarm systems. It supports Mitsubishi LINK RS‑485 communication, offers isolated output circuits, and includes LED status indicators for each channel.
The document explains how to configure module address and baud rate via DIP switches or JTDDMX software, describes wiring of the DC24 V power supply and RS‑485 network, and provides detailed communication protocols for writing, reading, and checking output states. Installation, debugging, and example applications with PLCs are also covered. This manual is written in Chinese.

Set the address using DIP switch SW1 bits 1‑5 (A0‑A4) in binary, giving addresses from 0 to 31.
Select the baud rate with SW1 bits 6‑8 (BPS0‑BPS2), which provides rates from 1.2 kbps up to 115.2 kbps.
The module consumes up to 1350 mW, not counting the power used by the output channels.
