Application Questions Answered

• What types of temperature sensors work with this module? The 140ARI03010 directly connects to platinum (Pt100-Pt1000) and nickel (Ni100-Ni1000) RTDs.
• Can I mix different sensor types on one module? Yes, each channel independently configures for specific sensor types and ranges.
• What's the difference between 2, 3, and 4-wire connections? More wires provide better compensation for lead resistance, improving measurement accuracy.
• How accurate are the temperature readings? Typical accuracy is ±0.1°C, suitable for most industrial process applications.
• Does the module detect sensor failures? Yes, it includes diagnostics for open-circuit and short-circuit detection.
• What industries use this temperature module? Ideal for food processing, pharmaceutical, chemical, and HVAC control systems.

Installation Tip: For optimal accuracy with 2-wire RTD connections, ensure lead resistance is minimized and consistent across all sensors.
