Schneider Electric 140CPU53414A

Discontinued (family EOL 2022)

Analysis reviewed: September 11, 2026

What should replace this part?

The documented replacement is Modicon M580 family. This is a platform migration, not a drop-in swap.

Plan the M580 migration CPU-first, and confirm bridge stock for your exact model

Your options

Migrate to Modicon M580, CPU first
UMAC converts the Unity application, and an adapter keeps the S908 I/O running so the CPU can move first and the I/O follows later.
Source refurbished or used
Refurbished and used channels exist for Quantum CPUs. Confirm availability and condition for your exact model.
Repair the original
Confirm exact-model repair coverage with a service center before planning around repair.

What will need to change?

SoftwareThe existing application — whether Concept, ProWORX, or Unity — moves to EcoStruxure Control Expert. Export the program in XEF format and validate the conversion scope for your application.
HardwareThe Quantum rack gives way to an M580 X80 rack. Move the firmware across with Unity Loader.

For anything not listed here, check the replacement manual against your existing configuration.

Technical evidence

The recommendation above is based on the sources listed here. OEM source means the manufacturer published it; third-party source means a distributor, repair company or reseller states it. Confidence reflects how directly those sources support the recommendation: High — directly supported by manufacturer documentation. Medium — supported by family-level, secondary, or otherwise less-direct evidence. Low — limited or indirect evidence; verify independently before ordering.

Schneider Electric maps the sibling 140CPU53414BC to the BMEP582040H. The A-suffix firmware differs, so this mapping does not transfer to the 53414A.
Source excerpt“53414BC replaced by BMEP582040H; A vs non-A flash executives not interchangeable”
View source · Note: A warning lead, not evidence for the 53414A. Don't order the sibling's target for this CPU.

Limitation: No exact 53414A-to-M580 catalog mapping is documented — the path is family-level with a CPU-first option. Confirm the target against your exact model before ordering.
