Description

Siemens 6ES7400-1JA01-0AA0 Rack

Product Dimensions：

The Siemens 6ES7400-1JA01-0AA0 is a core component of the SIMATIC S7-400 modular controller series. Specifically, it is a UR1 (Universal Rack) designed to house the various modules (CPUs, power supplies, I/O, and communication processors) that make up the PLC system.

As a “Universal Rack,” it supports both the P-bus (Peripheral bus) and the K-bus (Communication bus), allowing for full integration of all S7-400 module types.

Technical Specifications

Key Product Advantages

• Robust Scalability: With 18 slots, it provides maximum capacity for large-scale automation projects, reducing the need for multiple segmented racks.

• High-Speed Communication: The integrated backplane bus ensures seamless, high-speed data exchange between the CPU and peripheral modules.

• Durability: Built with high-quality materials designed for harsh industrial environments, offering high resistance to vibration and electromagnetic interference (EMI).

• Flexibility: The UR1 design allows it to be used as either a central rack (holding the CPU) or an expansion rack.

• Hot-Swapping Support: When used with appropriate modules, it supports the replacement of modules without shutting down the entire system, minimizing downtime.

Critical Considerations & Maintenance

• Heat Dissipation: Due to the high density of modules (18 slots), ensure the cabinet has adequate ventilation or active cooling to prevent CPU throttling or hardware failure.

• Grounding: Proper earthing of the rack is mandatory to ensure system stability and protect against electrical surges.

• Power Supply Positioning: Typically, the power supply module must be plugged into the leftmost slot (Slot 1) to distribute power across the backplane correctly.

• Empty Slots: It is recommended to use “dummy” covers for unused slots to prevent dust accumulation and maintain proper airflow.

Common Applications

The S7-400 series is the “powerhouse” of Siemens automation, making this rack ideal for:

1. Process Automation: Used extensively in oil and gas, chemical plants, and water treatment facilities.

2. Automotive Industry: Managing complex assembly lines and robotic integration.

3. Power Generation: Controlling turbines and power distribution systems where high reliability is non-negotiable.

4. Manufacturing: Large-scale food and beverage production lines.
