Selection Guide
Use the criteria below to confirm the 140ARI03010 is the right module for your application, or to identify the best alternative:
- Platform: If your system is Modicon Quantum → 140ARI03010 is the native choice. For M340 → consider BMXART0814. For M580 → consider BMAART0414H.
- Channel Count: 8 channels per module. For 16-channel density, consider stacking two modules or evaluating third-party high-density alternatives.
- Wiring Type: 4-wire RTD delivers highest accuracy (±0.1°C); 3-wire is standard for most industrial RTDs; 2-wire is suitable for short cable runs only.
- Environment: Standard environments → 140ARI03010. Corrosive or high-humidity environments → 140ARI03010C (conformal coated).
- Budget vs. OEM: OEM original recommended for safety-critical loops. Verified compatible alternatives available for non-critical monitoring points — contact Konmask for options.
- Lead Time Sensitivity: Konmask.com maintains stock of both new and refurbished units. Expedited shipping available for urgent MRO requirements.

Replacement & Compatibility FAQ
Q: Is the 140ARI03010C a direct replacement for the 140ARI03010?
A: Yes. The “C” suffix denotes conformal coating only. All electrical and functional specifications are identical. It is a drop-in replacement.
Q: Can I use the 140ARI03010 on a Modicon M340 or M580 system?
A: No. The 140ARI03010 is mechanically and electrically specific to the Quantum backplane. M340 and M580 use different form-factor modules (BMX and BM series respectively).
Q: What RTD sensor types are supported?
A: The module supports Pt100, Pt1000, Ni100, Ni1000, Cu10, and other standard IEC 60751-compliant RTD types. Refer to the Unity Pro/Control Expert configuration for the full sensor type list.
Q: Does Konmask.com provide a warranty on used modules?
A: Used (as-is) modules are sold with an inspection report but without warranty. Refurbished modules carry a 6-month warranty. Contact us for details.
Q: What is the typical lead time for the 140ARI03010?
A: In-stock units ship within 1–3 business days. Out-of-stock units typically have a 2–6 week lead time depending on sourcing. Contact us for real-time availability.
Q: Can I mix 2-wire and 4-wire RTDs on the same module?
A: Yes. Each channel is independently configurable for 2-, 3-, or 4-wire RTD input via software configuration in Unity Pro / Control Expert.
