Product Description (Detailed Explanation)

The PS 405 is a robust, industrial-grade power supply specifically engineered for the modular S7-400 system. It is installed in the leftmost slot of the S7-400 rack.

• Conversion: It takes a wide-range DC input and provides two stabilized output voltages to the backplane: 5V DC (for internal logic) and 24V DC (for interface circuits and relay coils).

• System Integration: It communicates with the CPU via the backplane to provide diagnostic information regarding power status and battery health.

• Backup Support: It features integrated battery compartments to house back-up batteries that retain the CPU’s memory and real-time clock during power outages.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• High Current Capacity: Providing 10 Amps at 5V, this module can power large racks containing multiple high-density CPUs and communication processors (CPs).

• Comprehensive Diagnostics: Equipped with LEDs for “INTF” (Internal Fault), “BAF” (Battery Fault), and “BATT1/BATT2” indicators, allowing for instant troubleshooting.

• Redundancy Ready: Can be used in redundant power supply configurations (using specific racks) to ensure zero downtime in mission-critical applications.

• Rugged Construction: Designed for 24/7 operation in harsh industrial environments with high resistance to vibration and temperature fluctuations.

• Safe Memory Backup: The dual-battery design ensures that user programs and data are protected even during extended shutdown periods.

Precautions (Important Notes)

• Polarity: Ensure the 24V DC input polarity is correct. Although protected, incorrect wiring can cause system startup failure.

• Battery Replacement: Change batteries only when the power is ON if you wish to retain the CPU data during the swap. If the “BAF” light is red, the data is already at risk.

• Slot Restriction: This module must be plugged into the specialized power supply slots (usually Slot 1) of the S7-400 rack.

• Ventilation: Do not block the cooling vents at the top and bottom of the module. Overheating will trigger an internal thermal shutdown.

• Grounding: Ensure the rack’s PE (Protective Earth) rail is properly connected to ensure the power supply’s noise filters function correctly.

Product Applications (Typical Use Cases)

The 6ES7405-0RA00-0AA0 is found in the most demanding industrial sectors:

• Power Plants: Providing stable control power for turbine management and synchronization systems.

• Oil & Gas: Powering the controllers used in refinery DCS (Distributed Control Systems) where reliability is paramount.

• Automotive Manufacturing: Supporting large-scale assembly lines where high I/O counts require significant backplane current.

• Chemical Industry: Used in batch processing where power interruptions could lead to significant product loss or safety hazards.

• Mining & Steel: Operating in environments with high electrical noise, where the module’s internal filtering is essential.
