DDMF2-8ADP is a temperature acquisition module produced by Jietong Technology Co., Ltd. It adopts MODBUS RTU RS-485 communication mode, supports multiple configuration software, has line break alarm mode setting and digital/temperature data (output by temperature value x 10), analog input and communication circuit isolation, and power polarity protection.
The DDMF2-8ADP is an 8‑channel PT‑100 temperature acquisition module designed for PLC, PCS, and computer‑based control and data‑collection systems. It supports MODBUS/RTU communication over RS‑485, offers selectable baud rates, and includes features such as line‑break alarm and average‑value processing.
The manual covers hardware installation, power connection, sensor wiring, parameter configuration (both manual via DIP switches and software via the JTCDM tool), and integration with PLCs and PC‑based SCADA software. Detailed wiring diagrams, communication settings, and troubleshooting steps are provided to ensure reliable temperature monitoring. This manual is written in Chinese.
