Product Overview

The 140AVI03000 (Model: 140AVI03000) is a high-precision 8-channel differential analog voltage input module designed for the Schneider Electric Modicon Quantum PLC platform. This module is engineered to capture continuous voltage signals from a wide array of field instruments, including pressure transducers, flow meters, and level sensors, converting them into digital values for the PLC processor.

Equipped with high galvanic isolation and FM Class 1 Division 2 certification, the 140AVI03000 (Part Number: 140AVI03000) ensures reliable signal integrity in hazardous and electrically noisy industrial environments. The 8 differential inputs minimize noise interference, providing high-speed voltage monitoring with exceptional absolute accuracy. Its software-configurable nature allows engineers to tailor each channel to specific voltage ranges via Unity Pro or Concept software.
