🎯 Purpose:
The iR-AI04-VI module of the iR series by Weintek is designed for collecting analog voltage and current signals from sensors and transducers in automation systems.
It provides precise measurement of process parameters and transmits the data to PLC/HMI/SCADA systems.

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

💡 Functional Features:

• ✔️ Signal acquisition — measurement of voltage and current from sensors (pressure, temperature, level, flow, position, etc.).
• ✔️ Flexible configuration — each channel can be individually set to the required range (V or mA).
• ✔️ Direct integration with cMT-CTRL01 — used in CODESYS projects as an analog input module.
• ✔️ Scalability — can operate with other modules of the iR series (digital I/O, analog I/O, combined).
• ✔️ Reliability — galvanic isolation protects against interference, noise, and overloads.
• ✔️ High accuracy — 16-bit ADC ensures precise measurement even in dynamic processes.
• ✔️ Visual status check — LED indicators show module status (power, errors).
• ✔️ Easy installation — compact design and removable terminals simplify wiring and maintenance.
