SCHNEIDER 140AVO02000 Analog Output Module | Modicon Quantum

SCHNEIDER 140AVO02000 Analog Voltage Output Module – Modicon Quantum Series

When a Modicon Quantum PLC rack loses its analog output capability, the consequences ripple immediately through the process: control valves freeze in their last position, variable-speed drives lose their setpoint reference, and the DCS operator is left watching a flat line where a live process signal should be. In continuous-process industries — petrochemical, power generation, water treatment — that frozen output can trigger a cascade of safety interlocks or, worse, an undetected drift toward an out-of-spec condition. The 140AVO02000 is the module that prevents that scenario. It is the dedicated 4-channel analog voltage output card for the Modicon Quantum platform, engineered to deliver stable, repeatable ±10 V DC signals with the resolution and isolation characteristics that process-control loops demand.

Within the Quantum I/O family, the 140AVO02000 occupies the voltage-output tier — distinct from the current-output 140ACO02000 and the mixed-signal 140AIO33000 — making it the preferred choice wherever the field instrument or actuator requires a voltage-referenced command signal rather than a 4–20 mA loop. Schneider Electric introduced the Quantum platform as its flagship large-scale PLC architecture for heavy industry, and the 140AVO02000 has accumulated a substantial installed base across refineries, power plants, and municipal utilities worldwide, meaning spare-parts availability and engineering familiarity are both well-established.

Key Features & Benefits

• 12-bit voltage resolution — Delivers 4,096 discrete output steps across the ±10 V range, providing the fine-grained setpoint control required for proportional valve positioners and precision speed references without perceptible stepping artifacts.
• 4-channel simultaneous output — All four channels update within 1 ms of each other, eliminating phase skew between parallel control loops and satisfying the synchronization requirements of multi-axis or multi-stream process control.
• Direct Quantum rack compatibility — Plugs into any slot of a Quantum local or remote I/O drop without adapter hardware, reducing installation time and eliminating the wiring errors associated with signal converters.
• Channel-to-backplane isolation — Protects the CPU and adjacent modules from field-side transients, a critical safeguard in environments where ground loops or inductive switching events are common, consistent with IEC 61131-2 isolation requirements.
• ≥ 2 kΩ load impedance compatibility — Drives the full ±10 V swing into standard industrial actuator inputs without output droop, covering the vast majority of commercially available valve positioners and drive reference inputs.
• Proven long-term availability — As a catalogued Schneider Electric Quantum component with a large global installed base, the 140AVO02000 is supported by an established aftermarket supply chain, reducing the risk of extended downtime during unplanned maintenance events.

Industry & Equipment Applications

• Oil & Gas / Petrochemical — Setpoint reference for control valve positioners on distillation column reflux loops, compressor anti-surge control, and separator level control where ±10 V actuator inputs are specified.
• Power Generation — Speed reference output to turbine governor drives and excitation system voltage regulators in gas turbine and steam turbine control panels.
• Water & Wastewater Treatment — Flow setpoint commands to variable-frequency drives on pump stations, dosing pump speed control, and aeration blower modulation in municipal treatment plants.
• Pulp & Paper / Printing — Web tension control via dancer-roll actuator references and dryer section steam pressure setpoints where voltage-referenced drives are standard.
• Automotive Manufacturing — Weld current reference, paint-line conveyor speed synchronization, and press tonnage control in body-in-white and powertrain assembly lines using Quantum-based machine controllers.
• Chemical & Pharmaceutical — Reactor temperature setpoint output to thyristor heating controllers and agitator speed reference in batch processes governed by 21 CFR Part 11-compliant Quantum systems.

System Integration & Compatible Parts

Upstream (CPU / Communication): Compatible with all Modicon Quantum CPUs (140CPU31110, 140CPU43412A, 140CPU65150, 140CPU65160, etc.) via the Quantum local bus or via RIO drop using 140CRA93100 / 140CRP93100 remote I/O heads.

Downstream (Field Wiring): Requires a 40-pin front connector (Schneider P/N 140XTS00200 or equivalent). Field cables should be shielded twisted-pair for noise immunity in analog signal runs exceeding 10 m.

Power Supply: Powered from the Quantum rack backplane; rack power supply 140CPS11420 or 140CPS21400 must have sufficient 5 V capacity for the total module complement.

Equivalent / Substitute Models:

• 140ACO02000 — Current output (4–20 mA) alternative; suitable substitute only when field instruments accept current-loop references instead of voltage.
• 140AVO03000 — Extended-channel variant (if available in your Quantum revision); verify firmware and Unity Pro I/O map compatibility before substitution.
• Third-party Quantum-compatible analog output modules (e.g., from ProSoft or Prosoft Technology) may be considered for new installations but require full I/O map validation and are not drop-in replacements for existing Unity Pro projects without configuration changes.

Our Quality Assurance Process

1. Visual & Physical Inspection — Each unit is examined for connector pin integrity, PCB condition, label legibility, and absence of corrosion, burn marks, or mechanical damage before any further testing.
2. Functional Power-On Test — The module is seated in a live Quantum test rack and powered up; backplane communication, self-diagnostic LEDs, and channel-by-channel output voltage are verified against published specifications using calibrated instrumentation.
3. Firmware & Revision Verification — Hardware revision and firmware version are recorded and cross-referenced against Schneider Electric’s compatibility matrix to confirm suitability for the customer’s Unity Pro / Concept version.
4. Packaging & Documentation — Tested units are packed in anti-static bags with foam cushioning. Available documentation includes test report, hardware revision label photograph, and — where held in stock — original Schneider Electric datasheet reference.

Frequently Asked Questions

Q: Is the SCHNEIDER 140AVO02000 compatible with Unity Pro and Concept programming software?
A: Yes. The 140AVO02000 is natively supported in both Unity Pro (all versions) and the legacy Concept IEC programming environment. The I/O object is pre-defined in the Quantum I/O library; no custom driver or function block is required. Confirm the hardware revision against your Unity Pro version’s compatibility table if you are running a version older than Unity Pro 4.0.

Q: Can the 140AVO02000 be used in a Quantum Hot Standby (HSBY) redundant CPU configuration?
A: Yes. Analog output modules including the 140AVO02000 are fully supported in Quantum HSBY architectures. During a CPU switchover, the output channels hold their last commanded value until the standby CPU assumes control, minimizing process disturbance. Verify that your HSBY CPU firmware version supports the specific hardware revision of the module you are installing.

Q: What is the difference between the SCHNEIDER 140AVO02000 and the 140ACO02000, and how do I choose the right analog output module for my Quantum system?
A: The 140AVO02000 provides voltage outputs (±10 V DC) while the 140ACO02000 provides current outputs (4–20 mA or 0–20 mA). The correct choice depends entirely on the input specification of your field device: valve positioners and drives with voltage reference inputs require the 140AVO02000; those with current-loop inputs require the 140ACO02000. Check the actuator or drive datasheet for the analog input type before ordering. Mixing the two in the same project is common when a rack serves both voltage-referenced and current-loop field devices.
