Description

The Schneider Electric 140AVI03000 is an 8-channel differential multirange analogue input module engineered for the Modicon Quantum automation platform. It provides reliable acquisition and high-accuracy processing of continuous analog field signals, functioning as a primary signal conditioning interface between process transmitters, instrumentation, and the Quantum controller backplane.

Designed for versatile analog signal integration, the 140AVI03000 supports both unipolar and bipolar current and voltage configurations. It handles standard current loops including 0 to 20 mA and bipolar 20 mA, alongside voltage spans across +/-10 V, +/-5 V, 0 to 10 V, and 0 to 5 V. Featuring a 16-bit analog-to-digital resolution and built-in single-pole low-pass filtering (-3 dB at 847 Hz +/- 20%), the module delivers stable digitised process measurement with minimal electrical noise interference.

The module incorporates robust galvanic protection to maintain signal integrity in demanding industrial electrical environments, providing 500 Vrms AC / 750 V DC isolation between channels and the backplane bus, as well as 135 Vrms AC / 200 V DC channel-to-channel isolation. An addressing requirement of 9 input words enables complete diagnostic oversight, including fault detection for broken wires on 4...20 mA loops and scale overtaking on 1...5 V signals.

Features

• 8 differential analog channels supporting both unipolar and bipolar voltage and current signals.
• 16-bit resolution across all standard operating ranges for high-precision measurement.
• Integrated single-pole low-pass filter (-3 dB at 847 Hz +/- 20%) to mitigate high-frequency signal noise.
• Comprehensive isolation ratings: 500 Vrms AC (750 V DC) bus-to-channel and 135 Vrms AC (200 V DC) channel-to-channel.
• Built-in loop diagnostics capable of detecting broken wires (4...20 mA) and scale overtaking (1...5 V).
• Fast 10 ms cycle update time for real-time process monitoring.
• Front-panel LED diagnostic array providing immediate indication of bus active status, external faults, channel active states, and channel fault conditions.

Applications

• Interfacing process transmitters (flow, pressure, level, temperature) with Modicon Quantum control systems.
• Bipolar and unipolar voltage or current measurement in continuous process automation.
• Industrial monitoring applications requiring channel-to-channel electrical isolation to eliminate ground loops.
• Data acquisition in retrofit, expansion, or maintenance projects for Modicon Quantum automation racks.

Installation Guidelines

1. Safety Precaution: Disconnect all system power and field transmitter wiring prior to mounting, wiring, or servicing the module to prevent electrical shock or equipment damage.
2. Rack Insertion: Align the 140AVI03000 with the designated slot on the Modicon Quantum backplane rack. Firmly seats the module until the locking tabs snap into place.
3. Wiring Connections: Wire field inputs to the appropriate terminal block following recommended polarity and channel assignments. Use shielded twisted-pair cabling for analog signal lines to minimize ambient noise.
4. Shield Grounding: Connect cable shields to a single-point protective earth ground near the cabinet entry to prevent ground potential loops across isolated channels.
5. Power Verification: Confirm backplane power availability matches the 280 mA bus current requirement before powering up the rack.

Configuration / Commissioning / Replacement

• Software Setup: Configure module parameters within Unity Pro or Concept software, assigning the required 9 input words and specifying input ranges (current vs. voltage, unipolar vs. bipolar) per channel.
• Loop Diagnostics Verification: Test fault detection features by checking broken wire responses on 4...20 mA channels and scale limit detection on 1...5 V spans.
• Hot-Swapping / Replacement: Ensure system hot-swap procedures are followed if replacing the module under live rack power. Disconnect field terminal connectors, release backplane clips, insert the replacement 140AVI03000, and reattach the terminal block. Verify that the green Active LED turns on, indicating successful bus communications.
