140AVO02000C
Schneider Electric
Overview
The Schneider Electric 140AVO02000C is the conformal-coated variant of the four-channel analogue output module for the Modicon Quantum platform. It drives field devices with analogue signals and, with its protective coating, is better suited than the standard module to humid, washdown or corrosive environments.
The module provides four 12-bit outputs with a 3 ms update time and supports −10 to 10 mA current outputs, isolating channels at 500 V for one minute. It draws 700 mA from the backplane, dissipates up to 4.5 W and weighs about 0.3 kg. It carries CE marking and operates across 0–60 °C ambient with 5–95 % non-condensing humidity tolerance.
Application & Technical Notes
Electrically the 140AVO02000C matches the 140AVO02000; the C suffix adds conformal coating for harsher duty. Four 12-bit outputs with a 3 ms update time serve control loops where fast, stable analogue command is needed, and the 500 V channel isolation protects the rack from field-side transients. The 700 mA backplane draw and 4.5 W dissipation should be included in rack planning.
Integration follows standard analogue-output practice: confirm load impedance and cable length, use shielded and grounded wiring separated from power circuits, and map open-loop or out-of-range diagnostics in the controller. The coating extends service life where moisture, chemical vapour or dust are present.
Maintenance & Diagnostics
The 140AVO02000C is low-maintenance. During commissioning, calibrate each output against a reference or loop calibrator to confirm range and accuracy before service. Keep the rack within 0–60 °C and 5–95 % non-condensing humidity; the coating helps, but condensation should still be avoided.
De-energise the rack before insertion or removal. Because the coating can hide damage, inspect the module visually during shutdowns for cracked housing or overheating. Store spares between −40 and 85 °C in original packaging and recalibrate critical loops at planned intervals.
Sourcing & Procurement
The 140AVO02000C is the conformal-coated version of the 140AVO02000; choose it when humidity, washdown or contaminants are a concern. Genuine Schneider Electric modules are recommended for new builds and safety-related loops because they retain the original CE certification and warranty.
Compatible alternatives may cost less, but verify channel count, output ranges, isolation and approvals before substitution. For long-lead parts, refurbished genuine units from a reputable supplier are generally safer than clones. Buy from authorised distributors where possible and retain serial traceability.
