⚡ Preventa XPS MCM

The Schneider Electric Preventa XPS MCM is a modular, configurable safety controller that replaces multiple single‑function safety relays with one scalable, software‑configured “ safety brain ” for mid‑ to large‑size machines.

It is ideal when a machine has many safety devices(E‑stops, interlocks, light curtains, scanners, two‑hand controls) and needs centralised, TÜV‑certified safety logic.

🧩 Why It’s Used (Core Advantages)

• Replaces multiple relays
  Eliminates complex wiring when more than a few safety inputs are required.
• Highly modular
  Start with a CPU (8 inputs / 2 outputs) and expand up to 128 inputs and 16 outputs via side‑mounted slices.
• Software‑configured
  Uses SoSafe Configurable drag‑and‑drop logic blocks (AND/OR, muting, delays, EDM, etc.) — no PLC coding.
• Fast maintenance
  Removable backplane allows hot‑swap module replacement without rewiring.

⚙️ High‑Level Specs

• Safety ratings:
  PL e / Cat. 4(ISO 13849‑1) and SIL 3(IEC 62061)
• Communication options:
  EtherNet/IP, Modbus TCP, Profinet, CANopen — for diagnostics to the main PLC
• Scalability:
  Up to 128 inputs, 16 safety outputs, plus status/diagnostic outputs
• Diagnostics:
  Detailed fault codes, channel status, and device‑level monitoring

🧠 What It Replaces

• Multiple single‑function safety relays
• Hardwired logic for muting, EDM, two‑hand control, and gate monitoring
• Complex relay networks in large machines

⭐ One‑line summary

Preventa XPS MCM is a modular, software‑configured safety controller that centralises all machine‑safety functions into one scalable, TÜV‑certified system — replacing dozens of relays with clean, flexible logic.
