140AVO02000 Schneider Modicon Quantum 4-Channel Analog Output Module

Product Overview

The Schneider Electric 140AVO02000 provides four high-precision analog voltage outputs for the Modicon Quantum automation platform. This module converts digital values from the CPU into standard analog signals to control variable speed drives, valves, and other actuators. Supporting multiple bipolar and unipolar voltage ranges, it serves as a versatile interface for sophisticated process control. We deliver this module as 100% Brand New and Original, ensuring the linear accuracy and calibration stability required for demanding industrial loops.

Technical Specifications

The 140AVO02000 offers granular control with high resolution across all four independent channels.

Engineering Advantages

• Flexible Signal Scaling: Engineers can configure each channel independently for different voltage ranges (e.g., $\pm10$V or $1-5$V). This flexibility allows a single 140AVO02000 to manage a diverse array of field equipment simultaneously.

• Rapid Control Loop Response: With a settling time of less than 2 ms, this module provides the high-speed updates necessary for precision motion control and rapid-response pressure regulation.

• Superior Electrical Isolation: The module features 1000 Vrms isolation between the output channels and the backplane bus. This prevents field-side electrical noise or ground loops from corrupting CPU logic or damaging sensitive internal components.

• Hardened Industrial Design: Built to withstand 8 kV air electrostatic discharge and high electromagnetic fields ($10$ V/m), the 140AVO02000 maintains signal integrity even when installed near high-frequency power converters or heavy machinery.

• Comprehensive Diagnostics: Dedicated "Active" and "Fault" LEDs on the front panel provide instant feedback. These indicators help technicians distinguish between a logic-side communication error and an external power supply failure without opening the cabinet.

FAQs

• Does the 140AVO02000 require an external power supply?

  Yes. While the module draws $240$ mA from the backplane for logic, it requires an external $24$ V DC source to drive the analog output circuits. Ensure your external supply meets the $19.2$ to $30$ V DC limit.

• What happens to the outputs if the PLC enters "Stop" mode?

  You can configure the output behavior via the software (Unity Pro/Concept). Options typically include forcing the outputs to zero, holding the last valid value, or moving to a user-defined safety value to protect the process.

• Can this module drive a 4-20mA current loop?

  No. The 140AVO02000 is strictly a voltage output module. To drive current-controlled actuators, you should use the 140ACO02000 (current output version) or utilize a signal converter.

• What is the recommended calibration frequency?

  While the module features excellent temperature stability ($0.005\%$ per °C), we recommend an annual calibration check in critical applications to account for component aging and ensure maximum absolute accuracy.
