Description

Siemens 6ES7405-0RA00-0AA0 Power Supply Module

Product Dimensions：

The SIEMENS 6ES7405-0RA00-0AA0 is a high-performance Power Supply Module (PS 405) designed for the SIMATIC S7-400 PLC series. This module is specifically engineered to convert DC input voltage into the stabilized DC voltages required by the S7-400 backplane bus to power the CPU and various I/O modules.

Technical Specifications

The PS 405 is built for industrial robustness and reliability. Below are the key technical parameters:

Key Product Advantages

• Wide Range Input: The ability to handle varying DC inputs (24V to 60V) makes it versatile for different industrial power grids or battery-backed systems.

• High Power Density: Delivering 20 Amps at 5V, it can support large configurations with numerous signal modules and high-speed CPUs.

• Comprehensive Diagnostics: Equipped with LED indicators for:

  • INTF: Internal fault.

  • EXTF: External fault (e.g., input voltage missing).

  • BAF: Battery failure.

  • BATT1/BATT2: Status of the backup batteries.

• Redundancy Support: It can be used in redundant power supply configurations to increase system availability (MTBF).

Application Areas

This module is a staple in large-scale automation projects where the S7-400 platform is utilized:

• Power Plants: Controlling turbines and auxiliary systems.

• Automotive Manufacturing: Managing high-speed assembly lines.

• Oil & Gas: Used in distributed control systems (DCS) for refinery processes.

• Chemical Industry: Reliable operation in environments requiring complex logic and high I/O counts.

Important Considerations & Maintenance

• Slot Requirements: This is a “Double-Width” module. Ensure you have two adjacent slots available in your S7-400 rack (typically the leftmost slots).

• Battery Management: To retain the program and data in the CPU’s RAM during power loss, ensure the lithium batteries are replaced regularly. The BAF LED will warn you when the battery voltage is low.

• Heat Dissipation: Ensure the rack is mounted in an orientation that allows for natural convection cooling through the module’s ventilation slots.

• Safety First: Always disconnect the power source before inserting or removing the module to prevent electrical arcing or damage to the backplane.
