Features:

  • Medium‑sized rack for S7‑400 systems
  • Communication bus + P bus for full module interoperability.
  • CE, UKCA, UL, FM, RCM, KC, EAC, CCC – suitable for worldwide deployment.
The 6ES7400-1JA01-0AA0 is a UR2 rack offering 9 slots for S7‑400 modules. This slot count is ideal for medium‑sized automation applications that require a mix of power supplies, CPUs, communication processors, and I/O modules.For system integrators, the UR2 provides a balance between expandability and physical footprint. It can accommodate a redundant power supply setup, a single CPU, and up to 7 additional modules. When replacing an older UR2 rack, the 6ES7400-1JA01-0AA0 is a drop‑in replacement with the same slot positions and mounting holes. This minimizes mechanical redesign during legacy system upgrades or repairs.

The 6ES7400-1JA01-0AA0 includes both a communication bus (for CPU‑to‑CPU and CP communication) and a P bus (peripheral bus for I/O access). This dual‑bus architecture is fundamental to S7‑400 performance. The communication bus handles high‑speed data exchange between multiple CPUs and communication processors, enabling distributed processing. The P bus provides direct access to I/O modules from the CPU. Together, they allow the rack to support mixed configurations – for example, a CPU in slot 2 communicating with a CP in slot 4 while simultaneously reading inputs from an I/O module in slot 6.

The 6ES7400-1JA01-0AA0 carries an extensive list of international approvals: CE (Europe), UKCA (United Kingdom), UL (United States), FM (hazardous locations), RCM (Australia/New Zealand), KC (South Korea), EAC (Russia/Customs Union), and CCC (China). This allows the same rack to be used in machinery exported worldwide without re‑certification. For OEMs building equipment for global markets, this reduces engineering effort and speeds up time‑to‑market.

The 6ES7400-1JA01-0AA0 Siemens Rack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 6ES7400-1JA01-0AA0 is a UR2 rack for SIMATIC S7‑400 systems. It features 9 slots for installing power supplies, CPUs, communication processors, I/O modules, and function modules. The rack includes both a communication bus and a P bus (peripheral bus). It is designed for horizontal mounting in standard control cabinets.

When using the 6ES7400-1JA01-0AA0, engineers can build medium‑sized S7‑400 configurations. The 9 slots provide flexibility for mixed module types. The rack supports all S7‑400 series modules. It operates from 0°C to 60°C and can be stored/transported from 0°C to 70°C. Dimensions are 257.5 mm wide, 290 mm high, and 27.5 mm deep.

For legacy S7‑400 system expansions or replacements, the 6ES7400-1JA01-0AA0 provides a direct, compatible rack. It replaces older UR2 racks (e.g., 6ES7400-1JA00-0AA0) with the same mechanical footprint.
