Working Principle:
The X20PS9400 accepts a wide-range AC input (100–240 V AC) and converts it to a regulated 24 V DC output through a high-efficiency switched-mode power supply (SMPS) topology. The redundant design uses two independent power conversion stages that feed the same output bus. A control circuit continuously monitors both stages and seamlessly switches to the backup stage if the primary stage fails, ensuring zero interruption to connected I/O modules.

Advantages & Highlights:

• Guaranteed system uptime through true redundancy
• Wide input voltage range eliminates the need for transformers
• High efficiency (>90%) reduces heat generation and energy costs
• Compact form factor fits standard X20 mounting rail
• Comprehensive diagnostics enable predictive maintenance
• Compliant with EN 61131-2 for programmable controller power supplies

Applicable Industries:

• Packaging machinery
• Printing and converting machines
• Material handling and conveyor systems
• CNC machine tools
• Plastics processing equipment
• Food and beverage processing
• Automotive manufacturing lines

Installation Requirements:

• Mount on DIN rail TS 35 (EN 60715)
• Ensure minimum 10 mm clearance above and below the module for ventilation
• Connect input power using min. 1.5 mm² copper conductors
• Connect output using min. 2.5 mm² copper conductors
• Torque screw terminals to 0.8 Nm
• For redundant operation, install a second X20PS9400 in the adjacent slot

Usage Precautions:

• Do not exceed 10 A total output current under any condition
• Do not connect inductive loads directly without suppression diodes
• Verify input voltage range before initial power-up
• Ensure proper grounding of the protective earth conductor
• Do not operate in environments with corrosive gases or conductive dust
• Replace only with identical model X20PS9400 in redundant configuration
