Schneider Electric lifecycle dates differ by exact TSX or 140 catalogue number. Use the manufacturer references below to verify whether a CPU, rack or module can still be ordered or supported.
Lifecycle milestones by product family
| Family | Current reference status | Last order / production | Support / repairs |
|---|---|---|---|
| Modicon Premium (TSX) | Discontinued: service only | End of active sale 31 Dec 2018 (per Schneider notice reported by partners); se.com shows e.g. TSXP573634M and TSXAEY414 discontinued 2 Dec 2020 | End of standard service 31 Dec 2026 (se.com product pages) |

Some 140 I/O still orderable to 31 Dec 2030 per se.com | Per reference: e.g. 140CPU43412UC ended 8 Oct 2025; others 31 Dec 2026 to 31 Dec 2030 |
Lifecycle status may vary by exact catalogue number, hardware series and market. Confirm the precise reference with the manufacturer before relying on any deadline.
Successors and migration considerations
- Modicon Premium (TSX): Modicon M580 / Modicon X80 I/O (se.com names e.g. BMXART0414 for TSXAEY414)
- Modicon Quantum (140): Modicon M580 (Quantum Ethernet I/O / X80)
Migration is an engineering assessment, not an automatic drop-in substitution. Check program conversion, field wiring, communications, safety and commissioning requirements.
Find available spares
Inventory changes as items are sold and new consignments arrive, so we do not publish fixed quantities or condition claims on these reference guides.
Questions engineers ask
Does discontinued mean an installed controller must be replaced immediately?
No. It means the product's commercial lifecycle has changed, not that every installed unit has stopped functioning. Review spares availability, reliability, risk and your maintenance strategy.
Can Automation Outlet help source a legacy spare?
Yes. Send us the exact manufacturer part number, revision or series, quantity and required condition. Availability and testing status must be confirmed before an order.
Can a listed successor be swapped directly into my system?
Not necessarily. Replacement can require changes to software, wiring, communications, safety assessments and commissioning. Confirm compatibility with manufacturer documentation.
