140AVO02000C Schneider Analog Output Module Quantum

Schneider 140AVO02000C 4-Channel Analog Output

The 140AVO02000C analog output module delivers dependable signal conversion for complex industrial environments. Manufactured by Schneider Electric, this Modicon Quantum series component transforms digital commands into precise analog current signals. It suits applications like valve positioning, speed regulation, and process control where accuracy and repeatability matter most.

This module houses four independent output channels, each providing a user-configurable current range from -10 mA to +10 mA. Its 12-bit resolution offers fine granularity, so you can achieve smooth and responsive actuator movements. The 140AVO02000C requires only four output words for addressing, which simplifies integration with existing Quantum racks and controllers.

Technical Specifications

The 140AVO02000C operates with a source resistance of just 0.1 Ohm, which minimizes load effects and preserves signal integrity. Linearity stays within ±1 LSB, ensuring that the output faithfully follows the command value across the full scale. Update time is exceptionally fast at 3 milliseconds, making this module suitable for dynamic control loops that need quick reaction to setpoint changes.

For long-distance installations, the 140AVO02000C supports cable lengths up to 400 meters without significant degradation. Channel-to-channel isolation is rated at 500 V for one minute, protecting the system from ground loops and transient surges. The module draws 700 mA from the bus and dissipates a maximum of 4.5 W, which helps keep thermal load inside the rack manageable. Additionally, the built-in fuse carries a rating of 0.063 mA, adding an extra layer of overcurrent protection.

Mechanical and Environmental Parameters

Weighing only 0.3 kg (net), the 140AVO02000C fits neatly into standard Quantum racks. Its compact form factor leaves room for other I/O modules in high-density cabinets. The unit carries the CE mark, confirming compliance with European safety and EMC directives. Operating temperature ranges from 0°C to 60°C, while storage temperatures can span -25°C to 85°C. Relative humidity tolerance goes up to 95% non-condensing, making the module resilient in humid factory floors.

Installation and Wiring Guidance

Mounting the 140AVO02000C is straightforward. First, insert the module into an available slot on the Quantum backplane. Ensure the rack power supply can support the additional 700 mA bus current. Next, connect the output wiring using shielded twisted-pair cables to reduce electromagnetic interference. For optimal performance, keep signal wires away from high-voltage power cables. Termination resistors are not required internally, but you should verify that the receiving device presents an appropriate load impedance.

After wiring, configure the output words in your control program. The module maps each channel to a dedicated word, so you can update values individually or simultaneously. Remember that the update time remains fixed at 3 ms, so your logic scan cycle should align with this timing to avoid missed commands.

Packaging and Shipping

Your order for the 140AVO02000C includes the module itself and a quick-start wiring guide. The package does not contain configuration software, cables, or mounting hardware. We ship all orders via FedEx, UPS, or DHL, depending on your destination and preference. Each unit is individually packed in anti-static material and cushioned to prevent transit damage.

Frequently Asked Questions (FAQ)

Q1: Can the 140AVO02000C output voltage signals as well?
A: No. This module supports only current outputs in the -10 mA to +10 mA range. For voltage outputs, please consider other Quantum analog modules.

Q2: What happens if the load resistance is too high?
A: Excessive load resistance may reduce output accuracy or cause saturation. Always check that your load stays within the module’s compliance range for best results.

Q3: Is the 140AVO02000C compatible with older Quantum racks?
A: Yes. The module fits all standard Quantum backplanes, provided the rack has a free slot and sufficient power capacity.

Q4: Do I need external isolation amplifiers for each channel?
A: Not normally. The module already provides 500 V isolation between channels, which suffices for most industrial setups.

Q5: How do I verify correct module operation after installation?
A: Monitor the output words via your programming software and measure actual current at each terminal. The 3 ms update time should reflect changes almost instantly.
