Real-World Use & Application Scenarios
In complex industrial automation systems, precision analog output modules are essential for controlling actuators, valves, and other process elements where accurate analog signals represent physical parameters. The Schneider Electric 140AVO02000 is extensively utilized across diverse sectors such as chemical processing, water treatment, manufacturing, and energy, where delivering finely tuned bipolar voltage outputs is critical. Its use cases include driving analog actuators, controlling motor speeds, adjusting valve positions, and feedback signal generation within Modicon Quantum automation architectures.
Engineers select the 140AVO02000 for its ability to generate four independent analog output channels with robust 12-bit resolution and fast update cycles. It solves challenges related to signal integrity, channel isolation, and real-time responsiveness, thereby enhancing control fidelity in high-accuracy control loops, system diagnostics, and monitoring.

Product Introduction & Positioning
The Schneider Electric 140AVO02000 is a four-channel analog output module designed specifically for integration within the Modicon Quantum programmable logic controller (PLC) series. It produces bipolar voltage output ranges up to ±10 V, as well as unipolar outputs, enabling precise analog control over field devices.
As a modular unit in Quantum PLC configurations, the 140AVO02000 fits into a standard module slot and requires four consecutive 16-bit output words, providing scalability and ease of integration. It offers engineers the flexibility to implement both voltage and current-based control signals and is valued by systems integrators for its fast 3 ms update time and high channel-to-bus isolation, ensuring accurate and stable output without interference.
Key Technical Features & Functional Benefits
The 140AVO02000 features four analog output channels, each capable of generating bipolar voltage signals up to ±10 V with a source resistance of just 0.1 ohms for minimal signal degradation. The module offers 12-bit resolution, allowing for precise analog output with an accuracy error of ±0.15% full scale at 25°C and a linearity within ±1 least significant bit.
Isolation plays a critical role in this module’s design, providing 500 V channel-to-channel isolation with bus isolation rated up to 780 V AC for 60 seconds. Such high isolation protects against ground loops and noisy industrial environments, maintaining signal purity and measurement accuracy.
This module consumes a modest 4.5 watts and includes front-panel diagnostics: green LEDs signal normal channel operation, while red LEDs indicate channel faults. An active bus communication indicator LED provides clear status feedback to technicians. Update times of 3 ms and setting times around 700 µs support fast process control cycles essential in high-speed automation.
The 140AVO02000 supports wiring distances up to 400 meters with recommended wire gauges of 1-14 or 2-16 AWG, facilitating flexible field installations across large-scale plants.
