140ACO13000

Overview

The Schneider Electric 140ACO13000 is an eight-channel, multi-range analogue output module for the Modicon Quantum automation platform. It converts PLC values into field signals across current and voltage ranges that are software-configurable, allowing a single module type to serve varied actuators, valves and recording instruments.

Each channel is resolved at 12 bits with a 5 ms update time, and open-circuit detection on 4–20 mA ranges reports broken-loop faults to the controller. Isolation is channel-to-channel and channel-to-bus at 1780 V AC for one minute. The module occupies one slot, draws 550 mA at 5 V DC from the backplane and dissipates up to 5 W, with IP20 protection and a 0.4 kg footprint. Note that this module was announced as discontinued (end of sale 2025-04-17), so new designs should plan for availability and consider current equivalents.

Application & Technical Notes

The 140ACO13000 is a flexible analogue output module where software-configurable ranges reduce the number of distinct spare types a plant must stock. Eight channels serve moderate control schemes while leaving rack space for additional I/O, and 12-bit resolution is adequate for the majority of analogue control and indication duties. The 1780 V AC isolation between channels and bus protects the rack from field-side transients.

Integration should account for the higher backplane current (550 mA) and 5 W dissipation compared with four-channel outputs, and for cable length versus load impedance on each range. As with all analogue output, proper shielding, grounding and separation from power wiring preserve signal stability. Map open-circuit diagnostics in the controller so lost loops are detected promptly.

Maintenance & Diagnostics

The 140ACO13000 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 its rated environmental limits and ensure surrounding slots and ventilation are unobstructed because the module is convection-cooled and dissipates up to 5 W.

De-energise the rack before insertion or removal. Because the module is discontinued, maintain a small stock of genuine spares for critical systems and document the replacement path. Store spares in a dry environment within the rated storage range, and recalibrate safety- or quality-critical loops at planned intervals.

Sourcing & Procurement

The 140ACO13000 is announced as discontinued (end of sale 2025-04-17), so availability is the central procurement concern. For existing systems, genuine Schneider Electric spares or reputable refurbished genuine units are the lowest-risk options; verify the supplier and retain serial traceability. For new designs, evaluate the current Schneider analogue output equivalents rather than designing around an end-of-sale part.

If considering third-party or compatible modules, confirm channel count, ranges, isolation (1780 V AC) and certifications before substitution, since mismatches can affect approvals and loop performance. Buy from authorised distributors where possible and keep the manufacturer part number on record for audits.
