THMK-4013 is a three-channel resistance temperature detector (RTD) input module with various features and characteristics.
The THMK-4013 is a three‑channel RTD input module that accepts PT100 sensors in 2‑ or 3‑wire configurations and communicates via two RS‑485 ports. It can be linked directly to popular HMI panels and SCADA software such as iFIX, MCGS, and the Yuanxiang protocol, as well as ModBus and PPI.
The manual covers hardware layout, power and signal terminals, DIP‑switch address and baud‑rate settings, smart‑interface usage with a data monitor, and detailed parameter configuration for basic, communication and alarm functions. This manual is written in Chinese.

It measures temperatures from –50 °C up to +450 °C.
The module provides three independent RTD input channels.
It supports the Yuanxiang proprietary protocol, ModBus and Siemens PPI.
The address is set via the 8‑bit DIP switch; bits 1‑6 represent the binary address (0‑63).
