Product Details

140-AVI-030-00 Product Description

The Schneider Electric 140AVI03000 is a high-precision analog voltage input module engineered for seamless integration within the Modicon Quantum PLC platform. Designed to operate as a core signal acquisition node in distributed and centralised control architectures, this module delivers reliable, low-noise voltage measurement across demanding industrial environments. Whether deployed in continuous process control, power distribution management, or discrete manufacturing automation, the 140AVI03000 provides the signal fidelity and system compatibility that modern control engineers require.

As part of the Schneider Electric 140-series I/O family, this module slots directly into the Quantum backplane, enabling tight integration with the CPU layer, power supply infrastructure, and communication network without additional signal conditioning hardware. Its architecture-ready design reduces engineering overhead during commissioning and supports long-term maintainability across the full system lifecycle.

The 140AVI03000 is most effective when deployed as part of a fully integrated Modicon Quantum automation platform. In a typical Quantum rack configuration, the module operates alongside the 140CPU65160 or 140CPU67160 Unity Pro-compatible processors, which handle real-time scan cycle management and deterministic I/O polling. The backplane — typically a 140XBP01600 (16-slot) or 140XBP01000 (10-slot) chassis — provides the physical and electrical bus that connects the 140AVI03000 to the CPU and power supply without additional wiring overhead.

Power integrity is maintained by the 140CPS11420 or 140CPS21400 power supply modules, which deliver regulated 24 V DC to the backplane bus. Stable power is critical for analog signal accuracy; voltage ripple on the supply rail directly affects measurement resolution, making the selection of a matched Quantum power supply a non-negotiable element of system design.

For applications requiring remote I/O expansion — common in large-footprint plants where field instruments are distributed across multiple control cabinets — the 140AVI03000 can be deployed in remote racks connected via the 140CRP93200 RIO head module. This configuration allows analog signals from remote field zones to be transmitted over the Quantum RIO coaxial cable network to the main CPU rack, preserving signal integrity across distances that would otherwise require local signal conditioning.

Ethernet connectivity is extended through the 140NOE77101 Ethernet TCP/IP communication module, enabling the Quantum rack to participate in plant-wide SCADA networks, OPC-DA/OPC-UA data exchange, and remote diagnostics via Unity Pro or Vijeo Citect HMI platforms. When PROFIBUS DP field device integration is required — for example, connecting variable frequency drives or intelligent field transmitters — the 140CRP31200 PROFIBUS DP master module provides the protocol gateway within the same backplane.

On the output side, the 140AVI03000 works in tandem with analog output modules such as the 140AVO02000 to form closed-loop control architectures for flow, pressure, temperature, and level regulation. Digital I/O modules including the 140DDI35300 (discrete input) and 140DDO35300 (discrete output) complement the analog layer, providing the mixed-signal I/O density required in process plant interlocking and safety shutdown sequences.

For applications demanding high availability, the Quantum platform supports hot-standby CPU redundancy using the 140CPU67160S redundancy processor pair, with the 140AVI03000 continuing to serve as the shared I/O node. This architecture ensures that analog signal acquisition remains uninterrupted during CPU failover events, a critical requirement in continuous process industries such as petrochemical refining and power generation.

Manufacturing & Discrete Automation: In automotive body-in-white and general assembly lines, the 140AVI03000 acquires analog feedback from servo amplifiers, torque transducers, and linear position sensors. Integrated with the Quantum CPU and Unity Pro ladder/function block programs, it enables real-time quality monitoring and adaptive process control without external signal converters.

Power Distribution & Energy Management: Substations and medium-voltage switchgear panels use the 140AVI03000 to monitor current transformer (CT) and potential transformer (PT) secondary outputs. Paired with the NOE Ethernet module and a Vijeo Citect SCADA system, operators gain real-time visibility into load profiles, power factor, and harmonic distortion across distribution feeders.

Petrochemical & Refinery Process Control: In distillation column and reactor temperature control loops, the 140AVI03000 reads 0–10 V signals from temperature transmitters and pressure transducers. Its 12-bit resolution supports the tight control band tolerances required in exothermic reaction management, where ±0.5°C deviations can affect product yield and safety margins.

Water & Wastewater Treatment: Municipal water treatment facilities deploy the 140AVI03000 to monitor flow meters, pH sensors, dissolved oxygen probes, and turbidity analysers. The module's multi-channel architecture allows a single Quantum rack to consolidate signals from an entire treatment stage, reducing panel footprint and simplifying SCADA integration.

Mining & Metallurgy: Conveyor belt load monitoring, crusher motor current feedback, and flotation cell level control are typical applications in mineral processing plants. The 140AVI03000's robust operating temperature range and backplane isolation make it suitable for the electrically noisy environments characteristic of mining control rooms.

Packaging & Material Handling: High-speed packaging lines use the 140AVI03000 to read tension control signals, web guide sensor outputs, and fill-level transducer feedback. Integration with the Quantum CPU's high-speed scan mode ensures that analog data is refreshed within the cycle time constraints of servo-coordinated motion sequences.

Q1: Is the 140AVI03000 compatible with both local and remote Quantum racks? Yes. The 140AVI03000 is fully compatible with local Quantum backplanes (140XBP01600, 140XBP01000) and remote I/O racks connected via the 140CRP93200 RIO head module. In remote configurations, the module's analog data is transmitted over the Quantum RIO coaxial network to the main CPU rack, with no loss of resolution or scan cycle penalty beyond the inherent RIO network latency. Ensure that the remote rack power supply (140CPS11420 or equivalent) is correctly sized for the total backplane current draw including the 140AVI03000.

Q2: What engineering steps are required to commission the 140AVI03000 in a Unity Pro project? Commissioning requires adding the 140AVI03000 to the Quantum rack configuration within Unity Pro's hardware editor, selecting the correct slot position, and configuring the input range (0–10 V or ±10 V) per channel via the module's configuration dialog. I/O mapping is then performed in the application program to link physical channel addresses to process variables. Calibration verification using a precision voltage source is recommended before live process connection. No firmware update is required for standard Unity Pro v4.x and later projects.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time for replacement units? The 12-Month Warranty covers manufacturing defects, premature component failure, and functional non-conformance under normal operating conditions from the date of shipment. It does not cover damage resulting from incorrect installation, overvoltage events, or environmental conditions outside the module's rated specification. NANKMOS maintains in-stock inventory of the 140AVI03000 to support rapid replacement requirements; standard lead time for stocked units is 3–7 business days for international shipments. For critical spares planning, we recommend maintaining at least one replacement module per Quantum rack in high-availability installations.
