Core Function for Precision Signal Acquisition

The Schneider 140AVI03000 is an 8-channel analog input module for the Modicon Quantum series. This module acquires precise differential voltage signals from field transmitters and sensors. It supports a maximum input voltage of 50 VDC and handles up to 25 mA on its differential channels. Consequently, it provides reliable data conversion for monitoring critical process variables like temperature, pressure, and flow.

Differential Input Design and System Integration

This module features eight differential input channels for superior noise rejection in industrial environments. Its design requires 9 input words in the controller’s I/O mapping for proper configuration and data transfer. The 140AVI03000 has a bus current requirement of 280 mA from the Quantum backplane for operation. Furthermore, it operates reliably in high-humidity environments up to 95% non-condensing.

Detailed Technical Specifications

Engineered as a standard-format Quantum module, it integrates seamlessly into existing system racks. Its efficient design results in a low power dissipation of only 2.2 watts. The following table details its complete electrical, channel, and system integration parameters.

Application in Process Monitoring and Control

Install this module in a Quantum rack to interface with a variety of 4-20mA transmitters or 0-10VDC sensor outputs. Its differential input design is ideal for environments with significant electrical noise or long cable runs. The Schneider 140AVI03000 delivers the accurate signal conditioning needed for complex control strategies. Therefore, it is a fundamental I/O component in water treatment, chemical processing, and other precision process automation applications.
