Product Description for Siemens 6ES7400‑1JA11‑0AA0 SIMATIC S7‑400 Rack Module
1. Product Overview
6ES7400‑1JA11‑0AA0 is a brand‑new original aluminum‑made UR2 rack belonging to SIMATIC S7‑400 PLC system. It serves as the fundamental mechanical and back‑plane bus carrier for S7‑400 controllers. This UR2 rack contains 9 module slots and supports both central rack (CR) and distributed expansion‑rack (ER) installation modes. It can accommodate two S7‑400 power‑supply modules for redundant power configuration, as well as CPU modules, communication processors, digital and analogue I/O modules and interface modules. The built‑in P‑bus and K‑bus transmit power and high‑speed bus signals among all plugged‑in modules. It builds the hardware foundation for high‑end PLC control systems widely deployed in petro‑chemical plants, power stations, metallurgy equipment, large‑scale production lines and PCS7 process‑control projects. The whole rack is mounted inside industrial control cabinets and forms a compact modular‑structure S7‑400 automation system.
2. Main Functions
- Mechanical Fixing and Positioning
It provides standard slot positions to firmly install S7‑400 series modules. Anti‑vibration aluminum‑alloy structure prevents modules from loosening under workshop vibration conditions.
- Back‑Plane Bus Transmission
Integrated P‑bus (Process bus) and K‑bus (Communication bus) deliver 5 V DC power, internal data signals and MPI communication signals between all inserted modules.
- Redundant Power‑supply Support
Two PS407 power‑supply modules can be mounted on this rack. Hot‑standby redundant power supply ensures continuous system running when one power‑supply unit fails.
- System Expansion Realization
When used as an expansion rack together with IM460‑IM461 interface modules, it expands installation slots away from the central rack to reduce long‑distance wiring.
- Heat‑Dissipation Structure
Aluminum profile accelerates heat dissipation for CPUs and high‑power modules, avoiding overheating failures for long‑term continuous operation.
- Compatibility Guarantee
It matches all standard S7‑400 series modules and works with STEP‑7 software for hardware configuration and system diagnosis.
- Galvanic Isolation Design
Internal bus structure isolates field‑side interference to protect back‑plane circuits against surge currents from high‑power actuators.
