JTPLC technology CMDF2-8ADP PT-100 platinum resistance ManualVer 4.1

About this manual

The CMDF2-8ADP is an 8‑channel three‑wire PT‑100 temperature‑measurement module designed for PLC, DCS, PCS and PC control systems. It offers 12‑bit resolution (0.1 °C) and supports temperature ranges from –50 °C up to 200 °C (or –50 °C to 410 °C in extended mode). The module communicates via Modbus RTU over RS‑485 with adjustable baud rates from 600 to 115200 bps.

Installation requires a DC 9‑30 V power supply (up to 60 mA) and provides isolated RS‑485 terminals for wiring. Parameter settings such as address, baud rate, and channel configuration are performed through the SET/SEL registers. The manual includes wiring diagrams, register tables, and troubleshooting tips for reliable operation. This manual is written in Chinese.
