Description

Schneider 140AVI03000 – 8-Channel Multirange Analog Input Module

Product Overview

The 140AVI03000 is an 8-channel differential analog input module for the Schneider Electric Modicon Quantum automation platform. It accepts multiple current and voltage signal ranges, allowing one module to interface with different field instruments without requiring separate hardware for each signal type. Supported ranges include ±20 mA, 0–20 mA, ±10 V, ±5 V, 0–10 V, 0–5 V, with 1–5 V and 4–20 mA configurations also documented for the module. Each channel is individually configurable, making it suitable for process transmitters, pressure and flow instruments, position sensors, and other analog field devices. The module provides 16-bit conversion capability, a 10 ms update time, channel and bus isolation, and broken-wire detection for 4–20 mA signals. Schneider Electric lists it as a discontinued Modicon Quantum product, with end-of-service scheduled for December 31, 2030.

Technical Specifications — 140AVI03000

The published Quantum documentation specifies 16-bit resolution, 280 mA bus current consumption, and differential input architecture.

Key Features and Benefits — 140AVI03000

• Eight independently configurable analog input channels.
• Supports both voltage and current measurement.
• Suitable for mixed-signal process instrumentation.
• 16-bit conversion provides detailed signal measurement.
• Channel-to-bus isolation helps protect the control system from field-side electrical conditions.
• 10 ms update time supports relatively fast process monitoring.
• Broken-wire detection is available for 4–20 mA applications.
• LED indicators provide channel and fault status.

The flexible input ranges are the main practical advantage. A single module can accommodate several transmitter types, reducing the need for multiple analog-input variants in a Quantum installation.

Installation and Maintenance — 140AVI03000

Before replacement, verify the Quantum rack configuration, channel signal ranges, field wiring, addressing, and application software configuration. Current and voltage inputs have different connection requirements, so terminal wiring should be documented before removal.

During maintenance, inspect the terminal block, rack connector, field wiring, and channel-status LEDs. If a 4–20 mA channel reports an abnormal value, check the transmitter and loop wiring before replacing the module. After installation, verify each configured channel against a calibrated field signal.

Personally, I would record every channel’s configured range before removing the module. This is a simple step, but it can prevent commissioning errors when several signal types share the same card.

Product Warranty — 140AVI03000

Warranty coverage should be confirmed with the supplier according to the actual supplied condition, such as new surplus, refurbished, or tested-used. For legacy Quantum spares, procurement records should include the exact reference, hardware revision where applicable, inspection status, and warranty period.

Schneider Electric has discontinued this product and lists December 31, 2030 as its end-of-service date. The manufacturer recommends the Modicon X80 BMXAMI0810 as a replacement, but system compatibility and application requirements should be evaluated before migration.

When sourcing the Schneider 140AVI03000, verify the existing Quantum rack and channel configuration before purchase.
