Features & benefits

• Wide DC input range (24–48 V isolated) supports flexible system power architectures.
• High 24 V output power (31.2 W) combined with substantial 3.3 V logic supply (15 W) supports denser I/O configurations and processors.
• Built‑in secondary protections and alarm relay improve system safety and fault visibility.
• Compact IP20 module with high MTBF for reliable operation inside control cabinets and distributed racks.

Installation and service notes

• Connect DC supply and protective earth to the 5‑pin line connector; use the 2‑pin connector for alarm relay wiring per Schneider Electric wiring diagrams.
• Ensure upstream protection and cabling accommodate specified inrush and activation characteristics.
• Use RESET push‑button for cold restart after fault clearance.
• Install inside IP20‑rated enclosures and respect environmental and altitude derating limits. Refer to the official datasheet for connector pinout and detailed mechanical mounting guidance.
