Schneider Electric ASSY-12149 – OEM Replacement Assembly for Industrial Control Systems

The Schneider Electric ASSY-12149 is an original OEM assembly typically used as a board-level replacement inside Schneider-controlled machines and panels. From my experience, this kind of spare part is the quickest way to get a downed line back into production without re-engineering the whole control cabinet. You might notice that lead times for complete modules can fluctuate, while a direct assembly swap often restores functionality in one service window.

One thing I appreciate is how these assemblies are designed to slot into the existing host unit/backplane, so wiring stays mostly intact and compatibility is predictable. It seems to be the preferred approach for maintenance teams who want minimal downtime and a parts trail that matches Schneider’s documentation.

Our Order Process & Guarantees

• Warranty: 365 days from delivery
• Delivery: 1 week when in stock; no more than 1 month latest
• Payment: 50% advance; balance before dispatch
• Express options: FedEx, UPS, DHL
• Pre-shipment functional check and protective packaging for ESD-sensitive parts

Key Features

• Genuine Schneider OEM assembly – Ensures form-fit-function alignment with the original design.
• Board-level replacement – Installs inside the host module; no cabinet redesign required in most cases.
• Backplane-powered – Typically draws 24 VDC from the host unit’s internal power, simplifying field wiring.
• Controlled compatibility – Works within the intended Schneider platform, helping avoid firmware or parameter surprises.
• Service-friendly – ESD-protected packaging and straightforward mounting points for quick swap-outs.

Technical Specifications

Signal I/O	No direct field I/O; interfaces internally through the host module’s connectors
Communication Interfaces	Internal system bus / board-to-board connectors (no external ports on the assembly)
Installation Method	Board-level replacement; secure with screws/standoffs per Schneider service manual; ESD handling required

Application Fields

While the exact host platform can vary, assemblies like ASSY-12149 are commonly found in:

• Packaging and converting lines (cartoners, wrappers, labelers)
• Material handling systems (conveyors, sorters, palletizing cells)
• F&B and pharma equipment with strict uptime expectations
• Light assembly and machine tools using Schneider control platforms

A maintenance lead at a beverage plant told us they swapped an ASSY-series board in under 30 minutes and brought the filler back online without touching any field wiring—exactly the kind of downtime win most teams aim for.

Advantages & Value for Procurement

• Reliability: Genuine Schneider parts typically maintain original MTBF and thermal performance.
• Compatibility: Form-fit-function alignment reduces the risk of firmware or parameter mismatches.
• Cost Control: Replace only what’s failed—often less expensive than purchasing a complete module.
• Traceability: OEM labeling and batch trace support your quality and audit processes.
• Support: Access to installation guidance and post-sales follow-up if something doesn’t behave as expected.

Installation & Maintenance

• Environment: Install in a clean, dry, ventilated control cabinet; avoid corrosive gases and excessive vibration.
• Power & Wiring: Isolate all power (24 VDC and mains) before service. Photograph and label connectors before removal.
• ESD Safety: Use a grounded wrist strap and ESD mat. Handle by edges; never touch component leads.
• Mounting: Seat the board evenly into the host; tighten screws to the torque recommended in Schneider’s service documentation.
• Commissioning: After installation, perform a visual check, restore power, and run a functional test at low load first.
• Routine Care: Keep filters clean, check for loose connectors during scheduled stops, and back up configurations. Firmware changes should follow the host platform’s release notes.

Quality & Certifications

• Manufactured under ISO 9001 quality systems
• RoHS-compliant materials and processes (typical for Schneider assemblies)
• Designed for use within CE/UL-certified Schneider systems when installed as intended
• Warranty: 365 days

Common Supporting Components (for reference)

To keep spares aligned with your installed base, teams often stock a few companion items. These are typical in Schneider-powered cabinets—please confirm against your BOM before ordering:

• ABL8RPS24030 / ABL8RPS24100 – 24 VDC Phaseo power supplies (3 A / 10 A) used to power control electronics.
• NSYAM Series DIN rails – For clean mounting and grounding in the control cabinet.
• ESD Service Kit – Wrist strap, mat, and antistatic bags to protect sensitive assemblies during handling.
