140ACO02000
Schneider Electric
Overview
The Schneider Electric 140ACO02000 is an analogue output module for the Modicon Quantum automation platform. It provides four output channels that drive field devices such as valves, actuators, drives and recorders with either voltage or current signals, allowing a Quantum PLC to command process equipment reliably.
The module fits a single Quantum slot, draws 480 mA from the backplane and dissipates about 2 W. Output health is reflected through status LEDs, and the module is engineered for 0–60 °C operation, 5–95 % non-condensing humidity and the electrically noisy conditions typical of industrial plants. It carries CE, cUL and FM Class 1 Division 2 certifications, making it suitable for hazardous-location installations when applied within the rated conditions.
Application & Technical Notes
The 140ACO02000 is the analogue counterpart to the 140ACI input modules, closing the control loop by converting PLC values into field signals. Four channels keep it flexible for smaller control schemes while leaving rack space for additional I/O. The module supports both voltage and current output ranges, so it can drive a variety of final elements without external signal converters.
When integrating, confirm the load impedance and cable length are within the module's capability, and observe the backplane current budget (480 mA) in your power planning. As with all analogue I/O, proper shielding, grounding and separation from power wiring reduce noise and improve stability. Output diagnostics should be mapped in the controller so open-loop or out-of-range conditions are detected promptly.
Maintenance & Diagnostics
The 140ACO02000 needs little routine maintenance. During commissioning, verify each output against a known load or a loop calibrator to confirm range and accuracy before the loop is placed in service. Keep the rack within 0–60 °C and 5–95 % non-condensing humidity, and ensure surrounding slots and ventilation are clear because the module is convection-cooled.
De-energise the rack before insertion or removal to protect the backplane. Inspect status LEDs periodically for fault indications, and store spares between −40 and 85 °C in original packaging. For safety- or quality-critical control loops, recalibrate against a reference at planned intervals and keep configuration records with the panel documentation.
Sourcing & Procurement
The 140ACO02000 is a four-channel Quantum analogue output module; confirm the required voltage or current ranges before ordering. Genuine Schneider Electric modules are recommended for new builds and safety-related loops because they retain the original CE, cUL and FM certifications and warranty. Compatible alternatives may be cheaper, but verify channel count, output ranges and isolation before substitution.
For long-lead or discontinued parts, refurbished genuine units from a reputable supplier are usually a lower-risk alternative than clones. Purchase from authorised distributors where possible, validate the seller, and retain the manufacturer part number and serial traceability for audit and warranty purposes.
Frequently Asked Questions
