140AVI03000C
Schneider Electric
Overview
The Schneider Electric 140AVI03000C is the conformal-coated variant of the eight-channel analogue voltage input module for the Modicon Quantum platform. It uses differential inputs to acquire voltage signals while rejecting common-mode noise, and its coating makes it better suited than the standard module to humid, washdown or corrosive environments.
The module draws 280 mA from the backplane, fits a single Quantum slot and weighs about 0.3 kg. It operates across 0–60 °C ambient with 5–95 % non-condensing humidity tolerance, and carries CE, cUL and FM Class 1 Division 2 approvals. Channel status is presented through LEDs.
Application & Technical Notes
Electrically the 140AVI03000C matches the 140AVI03000; the C suffix adds conformal coating for harsher duty. Eight differential voltage inputs provide moderate density at a 280 mA backplane draw, easy to accommodate in most rack power budgets. The coating extends service life where the module is exposed to moisture, chemical vapour or dust.
Integration follows standard analogue practice: confirm the voltage ranges, budget addressing words and backplane current, and use shielded, grounded wiring separated from power circuits. Map module diagnostics in the controller so channel faults are detected promptly, and confirm absolute maximum inputs are not exceeded on exposed wiring.
Maintenance & Diagnostics
The 140AVI03000C is low-maintenance. During commissioning, verify each of the eight channels and confirm the voltage signal is within range before the loop is trusted. Keep the rack within 0–60 °C and 5–95 % non-condensing humidity; the coating helps, but condensation should still be avoided.
De-energise the rack before insertion or removal. Because the coating can hide damage, inspect the module visually during shutdowns for cracked housing or overheating. Store spares between −40 and 85 °C in original packaging and recalibrate quality-critical channels at planned intervals.
Sourcing & Procurement
The 140AVI03000C is the conformal-coated version of the 140AVI03000; choose it when humidity, washdown or contaminants are a concern. Genuine Schneider Electric modules are recommended for new builds and safety-related loops because they retain the original CE, cUL and FM certifications and warranty.
Compatible alternatives may cost less, but verify channel count, isolation, accuracy and approvals before substitution. For long-lead parts, refurbished genuine units from a reputable supplier are generally safer than clones. Buy from authorised distributors where possible and retain serial traceability.

Description
| Note | The 140AVI03000C module from Schneider Electric functions as an analog input unit within the Modicon Quantum series. It is equipped with eight differential analog inputs, which are fundamental for accurate voltage measurements in process automation. This module necessitates nine input words for addressing, making integration into systems straightforward. The module can handle an absolute maximum input voltage of up to 50 volts DC. Each input has a specified impedance of 250 Ohm, which allows for optimal signal processing. Additionally, isolation between each channel and the bus is rated at 500 Vrms, ensuring effective noise and interference reduction. The update rate for the inputs is recorded at 10 ms, providing efficient response times essential for real-time applications. Local visual indication is accomplished through built-in LED signaling, allowing for quick status checks without additional equipment. The device demands a bus current of 280 mA for its operation and exhibits a power dissipation level of 2.2 watts. Weighing 0.3 kg, this compact module can fit into various control systems. In terms of durability, the 140AVI03000C is resistant to electrostatic discharge, rated at both 4 kV and 8 kV, alongside electromagnetic field resistance of up to 10 V/m. This ensures reliability and stability in industrial environments where electrical noise and fluctuations are prevalent. Overall, the Schneider Electric 140AVI03000C analog input module is crafted for precise data handling and robust performance. |
