Schneider Electric TSXP57204M – Modicon Premium PLC CPU for machine and process control

The Schneider Electric TSXP57204M is a Modicon Premium CPU module designed for established industrial installations that need dependable performance and long-term serviceability. From my experience, this CPU hits a sweet spot for OEM machinery, packaging lines, material handling cells, and water/wastewater skids where deterministic control and straightforward serial communications matter more than flashy extras. One thing I appreciate is how easily it drops into an existing Premium rack—most retrofits are fast, with minimal re-wiring.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: Typically 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Modicon Premium platform compatibility – Installs directly into TSX Premium base racks for quick swap-outs and expansions.
• Deterministic PLC scan performance – Suited for synchronized motion sequences, interlocks, and high-speed machine steps.
• Dual serial ports (TER/AUX) – Typical Unitelway/Modbus serial connectivity for programming, HMIs, and drives without extra comm modules.
• Battery-backed application retention – Helps preserve user program and system clock during power cycles; an optional memory card can be used for backup.
• Diagnostic LEDs and clear front access – You might notice that fault tracing and status checks are very direct on the front panel.
• Scalable I/O via backplane – No onboard I/O; simply add the required digital/analog modules to match your machine.
• Proven for brownfield upgrades – In many cases, teams use it to extend the life of installed Premium systems while keeping existing wiring and I/O.

Technical Specifications

Related or Supporting Products

• Base racks: TSX RKY series (choose slot count to match your I/O density and spare capacity).
• Power supplies: TSX PSY series (24 VDC or AC input options feeding the backplane).
• Ethernet communication: TSXETY4103 (adds 10/100 Ethernet for SCADA/MES or remote diagnostics).
• Programming cable: TSXPCX1031 (PC to TER port for configuration and programming).
• Digital I/O modules: TSX DDI/TSX DDO series (24 VDC inputs/outputs in various densities).
• Analog I/O modules: TSX AEY/TSX ASY series (voltage/current inputs and outputs with channel diagnostics on select models).
• Operator interface: Magelis HMI units with serial Modbus for direct connection to TER/AUX ports.

Quick field note: a packaging OEM told us they replaced a failing CPU with the TSXP57204M and were back in production in under an hour—no field wiring changes, just re-seated the memory card and restored the project. That’s typically how straightforward Premium-to-Premium swaps go.

Installation & Maintenance

• Environment: Mount the Premium rack in a clean, dry enclosure meeting IEC/UL industrial cabinet standards; provide ventilation to keep internal temps within 0–60 °C.
• Wiring & grounding: Use shielded twisted pair for serial lines, segregate control wiring from power cabling, and bond shields at a single point to reduce noise.
• Backplane loading: Verify rack power budget; the CPU draws 5 V from the backplane—leave headroom for I/O and comm modules.
• Battery & memory: Replace the CPU battery on the recommended interval (typically 3–5 years) and keep a verified backup on the memory card or engineering laptop.
• Firmware & backups: Update firmware only when required by Schneider Electric guidance; keep project archives and version notes with each change.
• Electrostatic precautions: Handle the CPU with ESD protection during installation or maintenance.

Quality & Certifications

• Certifications (typical for Modicon Premium): CE, UL/cUL, RoHS compliant
• Manufacturing quality: Produced under ISO 9001 quality systems
• Warranty: 365 days (our supply guarantee)

If you’re refreshing an existing Premium rack or planning a controlled upgrade path, the TSXP57204M seems to be one of the safer choices—minimal disruption, predictable behavior, and easy service access.
