Product Overview

The Schneider Electric 140AVO02000C controls analog devices with high precision. This module belongs to the Modicon Quantum series. It provides four independent analog output channels. The 140AVO02000C delivers current signals from -10 to 10 mA. You can control valves, positioners, and chart recorders directly. Its 12-bit resolution ensures fine control over your process. The “C” suffix adds conformal coating for environmental protection.

Technical Specifications

Output Characteristics

• Number of Channels: 4

• Output Type: Current (bipolar)

• Output Range: -10…10 mA

• Resolution: 12 bits

• Linearity: ±1 LSB

• Update Time: 3 ms per module

• Source Resistance: 0.1 Ohm

The 140AVO02000C updates all four channels every 3 milliseconds. This fast response suits dynamic process control applications. Each channel drives loads independently without interaction.

Addressing and Power

• Addressing Requirement: 4 output words

• Bus Current Required: 700 mA

• Max Power Dissipation: 4.5 W

• Fuse Rating: 0.063 mA (internal protection)

• Marking: CE certified

Your Quantum backplane must provide 700 mA for the 140AVO02000C. The module dissipates up to 4.5W as heat. This thermal output requires basic cabinet ventilation.

Isolation and Protection

• Isolation Between Channels: 500 V for 1 minute

• Channel to Backplane Isolation: 500 V DC

• Overload Protection: Current limited

• Short Circuit Protection: Yes (continuous)

The Schneider Electric 140AVO02000C isolates each channel from ground loops. A fault on one channel will not affect the other three. This protection saves downtime in critical processes.

Signal Cable Guidelines

Maximum Cable Distance

• Unshielded Cable: 200 meters maximum

• Shielded Cable: 400 meters maximum

• Recommended Cable: Belden 8762 or equivalent

Use shielded twisted pair cable for the 140AVO02000C over long runs. Connect the shield to ground at the module end only. Do not ground the shield at the field device side.

Wiring Terminals (15-pin female D-sub)

Pin 15 is the common shield connection for all four channels. The 140AVO02000C uses a standard 15-pin D-sub connector (female) on the module front.

Output Range and Digital Values

The 140AVO02000C maps digital counts to output current linearly:

Use 12-bit signed integers in your logic program. The 140AVO02000C rejects values outside the -2048 to +2047 range. This prevents unexpected output behavior.

Update Performance Details

• Channel Scan Order: Channel 0, 1, 2, 3 sequentially

• Individual Channel Update: 0.75 ms per channel

• Total Module Update: 3.0 ms for all channels

• Settling Time: < 100 µs to 0.1% of final value

The Schneider Electric 140AVO02000C updates channels in fixed order. Your control algorithm should account for this 0.75 ms offset. Fast-changing outputs need proper timing synchronization.

Environmental Specifications

Operating Conditions

• Temperature (Operation): 0…60°C (32…140°F)

• Temperature (Storage): -40…85°C (-40…185°F)

• Relative Humidity: 95% non-condensing

• Operating Altitude: Up to 5000 m (16404 ft)

Conformal Coating Protection

• Coating Type: Humiseal 1A33

• Protected Areas: All circuit board surfaces

• Resistance To: Humidity, dust, and mild corrosives

The “C” in 140AVO02000C stands for conformal coating. This coating prevents dendrite growth in humid environments. Use this module in food, beverage, or chemical plants.

Certifications

• Standards: UL 508, CSA C22.2 No 142

• Certifications: cUL, FM Class 1 Division 2, CE

• ESD Immunity: 4 kV contact, 8 kV air (IEC 801-2)

• EM Field Immunity: 10 V/m (IEC 801-3)

Installation Guidelines

Follow these steps to install the 140AVO02000C module:

1. Turn off power to the Quantum rack completely.

2. Insert the 140AVO02000C into any standard I/O slot.

3. Secure the module with top and bottom retaining screws.

4. Connect the 15-pin D-sub cable to the module front.

5. Route shielded wires to your field devices.

6. Apply power and check the green Active LED.

7. Download your analog configuration to the CPU.

8. Verify output values using a mA meter.

Do not exceed 400 meters of cable for the 140AVO02000C. Keep analog wiring separate from AC power cables. Use ferrite beads on long cable runs if needed.

Common FAQs

Q1: Can the 140AVO02000C output 4-20mA signals?
A1: No, the 140AVO02000C outputs -10 to 10 mA only. For 4-20mA output, use model 140ACO02000 or 140ACO13000.

Q2: What happens if I short two outputs on the 140AVO02000C?
A2: The Schneider Electric 140AVO02000C has short circuit protection. The output current limits safely until you remove the short.

Q3: Does the 140AVO02000C support HART communication?
A3: No, the 140AVO02000C does not support HART protocol. Use 140AVO03000 with built-in HART modem for smart devices.

Q4: How do I test a single channel on the 140AVO02000C?
A4: Force a digital value in your logic program. Measure the 140AVO02000C output current at the corresponding terminals. Compare to the value table above.

Q5: Can I replace a 140AVO02000 with the 140AVO02000C?
A5: Yes, the 140AVO02000C directly replaces the older 140AVO02000. The “C” version adds conformal coating for better reliability.
