The THMK-4013 manual explains installation, wiring, configuration and communication settings for the three‑channel RTD input module.
The THMK-4013 is a three‑channel RTD input module that accepts PT100 sensors and supports both 2‑wire and 3‑wire wiring. It provides dual RS485 ports for real‑time communication with HMI or PLC systems and can be powered from +10 V to +30 V.
The manual covers hardware layout, power and signal terminals, DIP‑switch address and baud‑rate configuration, smart‑interface usage, and detailed parameter settings for communication protocols (Yansong, ModBus, PPI). Appendices give protocol specifications and example command frames. This manual is written in Chinese.
