Compatible Replacement & Equivalent Models
When the 170AAI14000 is discontinued, hard to source, or requires a cost-effective alternative, the following models are commonly evaluated:
- 170AAI03000 – Schneider Electric Momentum 8-channel analog input (voltage/current); half the channel count, direct platform fit
- 170AAI14000C – Conformal-coated variant of the 170AAI14000 for harsh environments
- BMXAMI0810 – Modicon M340 8-channel analog input; requires M340 rack, not a drop-in replacement
- TSXAEY1600 – Modicon Premium 16-channel analog input; different platform, requires adapter evaluation
- Siemens 6ES7331-7KF02-0AB0 – S7-300 8-channel AI; cross-brand alternative requiring full system re-evaluation
- Allen-Bradley 1756-IF16 – ControlLogix 16-channel analog input; cross-brand, high-performance alternative
Note: Cross-brand replacements require full compatibility assessment of bus architecture, power supply, and software configuration before deployment.

Selection Guide
Use the following criteria to confirm the 170AAI14000 is the right module for your application:
- Channel Count: Do you need 16 analog input channels? If 8 channels suffice, consider 170AAI03000 to reduce cost.
- Signal Type: Confirm field devices output 0–10 V or 4–20 mA. For thermocouple or RTD inputs, evaluate 170AAI52040 (TC) or 170AAI52000 (RTD) instead.
- Environment: Standard industrial environment → 170AAI14000. Corrosive or high-humidity environment → 170AAI14000C (conformal coat).
- Platform: Existing Momentum system → 170AAI14000 is the direct fit. Migrating to M340 or M580 → consult Schneider migration guides for BMXAMI or BMXAMI0810 equivalents.
- Resolution Requirement: 12-bit resolution is sufficient for most process control. If 16-bit is required, evaluate BMXAMI0810 on M340 platform.

Replacement & Compatibility FAQ
Q: Is the 170AAI14000 still in production?
A: Schneider Electric has transitioned the Momentum platform to end-of-life. New production has ceased, but surplus and refurbished stock remain available. Contact us for current availability.
Q: Can I replace 170AAI14000 with a Modicon M340 module?
A: No direct drop-in replacement exists. M340 modules use a different rack and backplane. A platform migration project is required.
Q: What is the difference between 170AAI14000 and 170AAI14000C?
A: The “C” suffix denotes a conformal-coated PCB for protection against moisture, dust, and corrosive atmospheres. Electrically and functionally identical.
Q: Does the 170AAI14000 support HART protocol?
A: No. The 170AAI14000 does not support HART pass-through. For HART-enabled analog input on Momentum, evaluate third-party HART multiplexers.
Q: What adapter is required to use this module?
A: A Momentum communication adapter is required (e.g., 170ANR12090 for Ethernet/Modbus TCP). The I/O module alone cannot operate without an adapter.
