The 140AVI03000 is a Modicon Quantum analog input module with eight differential channels. Each configured channel can measure the documented voltage or current range, including unipolar 0–5 V, 0–10 V and 0–20 mA or bipolar ±5 V, ±10 V and ±20 mA operation.

The module occupies nine input words and applies 16-bit conversion. Channel range, field wiring, shielding and the installed terminal block must match the Control Expert hardware configuration before a replacement is energized.

A useful image set includes the complete module face, side nameplate and an unobstructed terminal-block photo. Keep channel labels and shield connections readable so the current/voltage configuration can be reviewed.

Can I wire 4–20 mA transmitters directly to 140AVI03000?

The module supports current measurement within its documented 0–20 mA range, but the loop-power source, polarity, terminal assignment and channel configuration must be confirmed. Keep the existing loop diagram and verify each channel in Control Expert.

Can voltage and current inputs be mixed on one 140AVI03000?

Use only combinations allowed by the module configuration and terminal wiring. Record the selected range for every channel and compare the existing field circuit before moving conductors; a visually similar terminal position does not confirm the correct signal mode.

Is 140AVI03000 an isolated analog input module?

Do not infer channel isolation from the product name. Schneider identifies this as an eight-channel differential multirange module; verify the grounding, common-mode and isolation requirements in the Quantum reference manual for the installed application.

What should be backed up before replacing 140AVI03000?

Save the Control Expert project and capture each channel range, scaling, alarm handling and rack address. Photograph the terminal block before removing it and label every conductor so polarity and shield routing are preserved.

What does Schneider recommend as a migration replacement for 140AVI03000?

Schneider lists BMXAMI0810 as a recommended X80-family replacement, but it is not a drop-in Quantum module. A migration requires a new rack/interface, wiring and application engineering review.

What information is required for a 140AVI03000 quotation?

Provide the full nameplate, terminal block, rack and slot, eight channel ranges, field voltages/currents, shielding method, quantity and destination. This lets the supplied module and support path be evaluated against the real installation.
