The 140ARI03010 is a high-precision RTD temperature input module developed by Schneider Electric for the Modicon Quantum Series automation architecture. This module is designed for direct temperature measurement from Resistance Temperature Detector (RTD) sensors, eliminating the need for external signal conditioning transmitters in many process control applications.
The module provides 8 independent high-resolution analog input channels, enabling accurate thermal monitoring in industrial environments with high electrical noise. Its built-in isolation and filtering technologies help maintain stable and reliable temperature acquisition for critical process control loops.

The 140ARI03010 is commonly deployed in:
Furnace and boiler temperature monitoring
Pharmaceutical production process control
HVAC environmental monitoring systems
Chemical and petrochemical processing plants
It is especially useful in applications requiring direct RTD probe connection, reducing wiring complexity and signal conversion errors.
Does the 140ARI03010 support multiple RTD wiring configurations?
Yes. The module supports 2-wire, 3-wire, and 4-wire RTD connections, allowing for lead resistance compensation to improve measurement accuracy.
How does the module detect sensor faults?
The module includes built-in diagnostics that detect open circuits or short circuits. Faults are transmitted to the PLC CPU and typically displayed using the front-panel fault indicator LED.
