🏭 Siemens 6ES7401-1DA01-0AA0 Central Rack for S7-400 PLC Systems
The Siemens 6ES7401-1DA01-0AA0 is a compact 4-slot central rack (CR3) engineered for SIMATIC S7-400 automation platforms. This foundational component provides the mechanical and electrical infrastructure for mounting CPU, communication, and I/O modules in space-constrained industrial environments.
🔧 Product Specifications
| Part Number | 6ES7401-1DA01-0AA0 |
| Product Line | SIMATIC S7-400 |
| Rack Type | CR3 Central Rack |
| Slot Capacity | 4 module positions |
| Backplane Bus | Integrated K-bus for module communication |
| Power Supply | Requires PS 405 or PS 407 series (sold separately) |
| Dimensions | 483 mm (W) × 290 mm (H) × 210 mm (D) |
| Mounting | Standard 19-inch rack or wall mount |
| Ambient Temp | 0°C to +60°C (horizontal installation) |
| Certification | CE, UL, cULus, FM approved |
💡 Industrial Use Cases
Manufacturing Automation: Serves as the backbone for assembly line controllers, robotic work cells, and material handling systems requiring compact PLC configurations.
Process Control: Ideal for water treatment plants, HVAC systems, and batch processing applications where cabinet space is limited but reliability is critical.
Machine Building: Perfect for OEMs integrating S7-400 control into packaging machinery, printing presses, or textile equipment with standardized 19-inch enclosures.
⚡ Engineering Advantages
Space Optimization: The 4-slot design reduces footprint by 40% compared to standard 9-slot racks while maintaining full S7-400 functionality for smaller applications.
Modular Scalability: Expand system capacity by connecting up to 21 expansion racks via UR2 interface modules, supporting configurations from 4 to 300+ I/O modules.
Hot-Swap Capability: Replace faulty modules during operation without system shutdown when using redundant power supplies, minimizing production downtime.
EMC Compliance: Shielded backplane design ensures electromagnetic compatibility in harsh industrial environments with variable frequency drives and welding equipment.
🛠️ System Integration Notes
- Compatible with all S7-400 CPUs (CPU 412 through CPU 417)
- Supports PROFIBUS DP, PROFINET, and Industrial Ethernet communication modules
- Requires one slot for power supply module (PS 405 2A, 5A, or 10A recommended)
- Maximum configuration current: 15A at 5V DC (verify total module consumption)
- Grounding point provided for functional earth connection per IEC 61131-2
Genuine Siemens component with global warranty support. Suitable for retrofit projects, spare parts inventory, and new S7-400 installations requiring compact rack solutions.
