Schneider 140ACO13000 Analog Output Module

Description

Product Introduction & Engineering Value

The 140ACO13000 handles eight independent analog current outputs and supports the three loop ranges commonly encountered in legacy process-control installations: 0–20 mA, 0–25 mA, and 4–20 mA. It is therefore suited to transmitting PLC-generated analog commands to valves, positioners, drives, indicators, and other current-loop devices.

For maintenance teams keeping a Quantum installation operational, the important issue is not simply finding an eight-channel analog module. The replacement must match the Quantum platform, channel configuration, field wiring, loop-power arrangement, and application scaling. Schneider now recommends the Modicon X80 BMXAMO0802 as the replacement product, but that is a migration decision rather than proof that the newer module is a mechanically identical drop-in replacement.

Technical Specifications

The published technical data confirms the 8-channel architecture, multirange current outputs, 6–30 VDC loop voltage, isolation specification, update time, and environmental ratings.

Field Wiring Detail

The module uses a field terminal arrangement associated with the 140 XTS 002 00 terminal strip, which must be treated as part of the installation interface rather than assumed to be included with the electronic module. The original Quantum documentation also specifies that all terminals labeled RETURN are internally common.

At startup, the channel outputs are specified to begin at 0 mA. That behavior matters when commissioning a replacement in a live process loop because the controlled device may initially move to its fail-safe or minimum-command condition depending on the external loop architecture.

Field Application & the “Trench” Experience

A typical legacy Quantum installation might use one 140ACO13000 to control several modulating devices in a process skid. Years later, Channel 4 begins reporting an output problem. The PLC program still executes normally, but the field positioner no longer receives the expected 4–20 mA command.

The maintenance engineer first verifies the PLC logic and scaling, then checks the field loop and transmitter/positioner wiring. Once those are ruled out, the module becomes the suspect. A replacement 140ACO13000 is installed, the original channel assignments are preserved, and each loop is individually forced and measured before automatic control is restored.

That last step matters. Do not assume that a healthy-looking analog module is electrically correct simply because its LEDs look normal. Measure the actual loop current.

Niche Application Scenarios

• Control-valve position commands in legacy chemical process skids
• Variable-speed drive references where a Quantum PLC provides a 4–20 mA speed command
• Damper and actuator positioning in large HVAC/process ventilation systems
• Flow-control loops where PLC output scaling drives a current-input valve positioner
• Multi-loop process batching systems requiring several independent analog commands from one Quantum rack

Transparency SOP: QA & Testing

For new-surplus or refurbished 140ACO13000 inventory, a proper receiving procedure should include more than a cosmetic inspection.

1. Identity verification
Confirm the complete part number 140ACO13000, manufacturer marking, module designation, and revision information.

2. Mechanical inspection
Check the housing, backplane connector, terminal interface, mounting hardware, labels, and front-panel indicators for damage or contamination.

3. Output verification
Test all eight channels where appropriate test equipment is available. Verify representative 0–20 mA, 4–20 mA, and 0–25 mA operating points rather than checking only one channel.

4. Isolation check
Where the test facility supports it, verify isolation according to the applicable manufacturer’s procedures.

5. PLC integration test
Install the module in a controlled Quantum test rack and confirm module recognition, addressing, output scaling, and channel response.

6. Documentation
Record the module revision, condition, test results, and whether the unit is new surplus, used, or refurbished.

This distinction is important because Schneider’s official page now classifies the 140ACO13000 as discontinued, while aftermarket suppliers continue to list new and refurbished inventory.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Treating BMXAMO0802 as a direct drop-in

Schneider identifies BMXAMO0802 as the recommended replacement. That does not mean you should remove a 140ACO13000 and install the X80 module without an engineering review. The Quantum and Modicon X80 platforms have different hardware architectures and configuration requirements.

PRO TIP: If the plant has a working Quantum rack and the objective is simply to restore production, an exact 140ACO13000 spare can be considerably less disruptive than beginning a platform migration during a breakdown.

⚠️ Trap #2 — Forgetting the external terminal strip

The Quantum documentation identifies 140 XTS 002 00 as the field wiring terminal strip and notes that it must be ordered separately. Verify what is actually included with the replacement module before assuming the complete field interface is present.

⚠️ Trap #3 — Ignoring unused channels

The original documentation warns that unused outputs can activate the F fault LED and recommends configuring unused channels in the 0–25 mA range to avoid this condition. That is an easy detail to overlook during commissioning.

⚠️ Trap #4 — Measuring voltage instead of loop current

This is a current-output module. When troubleshooting a 4–20 mA control loop, measure current through the actual loop or an appropriate calibrated test interface. A voltage reading alone can conceal an open-loop or incorrectly wired field device.

Dynamic FAQ

What is the Schneider 140ACO13000?

It is an 8-channel analog current-output module for the Modicon Quantum automation platform. It supports 4–20 mA, 0–20 mA, and 0–25 mA output ranges.

Is 140ACO13000 discontinued?

Yes. Schneider Electric lists the product as discontinued/end-of-commercialization. The U.S. Schneider page lists January 15, 2023 as the discontinuation date and December 31, 2030 as the end of standard service.

What is the recommended Schneider replacement?

Schneider recommends the Modicon X80 BMXAMO0802, an 8-output analog module supporting 0–20 mA and 4–20 mA. Engineering review is required before treating it as a replacement in an existing Quantum installation.

Does the module provide isolated analog outputs?

The published specification states 1780 VAC isolation between channels and the bus for one minute. Do not interpret that statement as meaning every aspect of the field circuit is individually isolated from every other field circuit; review the wiring documentation for the exact application.

What does New Surplus mean for this discontinued module?

New Surplus generally means unused original inventory that has been stored after production rather than recently manufactured. Because 140ACO13000 is discontinued, buyers should request photographs of the actual module, part-number label, packaging, and revision/date markings where available.

What warranty should I expect?

Warranty depends on the supplier and stock condition. Schneider’s discontinued status means an aftermarket seller’s warranty should not automatically be represented as an OEM Schneider warranty. For example, some aftermarket suppliers currently advertise their own two-year coverage on this part.
