🎯 Purpose:
The iR-AI04-TR module from the Weintek iR series is designed for collecting analog signals from thermocouples (TC) and resistance temperature detectors (RTD) in industrial automation systems.
It ensures accurate temperature measurement in technological processes and transmits data to PLC, HMI, and SCADA systems.

It can be used as:

• part of distributed I/O systems of the iR series via communication modules (iR-ETN, iR-COP, iR-ECAT),
• or directly as an analog input module for the cMT-CTRL01 controller running CODESYS.
