JTPLC technology DDMF2-8ADP PT-100 platinum resistance Manual
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.

Questions answered in these manuals
How do I set the module address?
The address is set with the DIP switch SW1; the first five bits represent the address (e.g., 00000 = 00H, 11111 = 1FH).
How can I change the communication speed?
Select the desired baud rate by configuring bits 6‑8 of SW1 (BPS0‑BPS2), which correspond to speeds from 1.2 kbps up to 115.2 kbps.
What is the default baud rate when the module is set to automatic mode?
In automatic mode the module defaults to a baud rate of 38400 bps.
