Siemens 6AG1591-1BA01-2AA0 CPU Front Panel V2

Applications

The Siemens 6AG1591-1BA01-2AA0 CPU Front Panel V2 is a front-panel component designed for use with the corresponding Siemens automation hardware. With a specified CPU width of 70 mm, it is intended for installations requiring the matching wider panel format.

In industrial control environments, front-panel components contribute to proper equipment assembly, organized cabinet layouts, and efficient maintenance. Selecting the correct part number is especially important when replacing components in established PLC installations.

Typical applications include:

• PLC system maintenance: Replacing a damaged, worn, or missing CPU front panel on compatible equipment.

• Control cabinet servicing: Maintaining the physical arrangement and appearance of installed automation hardware.

• Industrial equipment refurbishment: Supporting repair and refurbishment projects that require a matching front-panel component.

• Spare-parts inventory: Keeping model-specific Siemens components available for planned maintenance and unplanned repairs.

• Automation system upgrades: Supporting hardware replacement activities where the required panel version has been confirmed.

Before ordering, verify the target CPU model, the mounting interface, and the required hardware revision to ensure the component matches the intended installation.

Key Advantages

Model-specific identification

The complete Siemens part number, 6AG1591-1BA01-2AA0, helps maintenance and purchasing teams identify the requested CPU front panel and distinguish it from other variants.

70 mm CPU width

The specified 70 mm CPU width helps identify the intended panel format. This measurement should be checked against the compatible hardware assembly rather than used as the sole criterion for determining fit.

Lightweight design

With a stated weight of 0.148 kg, the component is easy to handle during routine servicing, replacement, and spare-parts preparation.

Supports efficient maintenance

Keeping the appropriate replacement panel available can simplify maintenance planning and help avoid unnecessary replacement of a larger assembly when only the front-panel component is required.

Version-aware replacement

The V2 designation provides an important identification detail when sourcing a replacement. Checking the version helps reduce the risk of selecting a visually similar but incompatible component.

Technical FAQs

Q1: What is the Siemens 6AG1591-1BA01-2AA0?

It is identified as a Siemens CPU Front Panel V2. Its intended use is associated with the front-panel assembly of compatible automation hardware. Confirm the precise application in the documentation for the target CPU.

Q2: What does CPU width mean for this product?

The specified CPU width is 70 mm. This identifies the stated width category for the component, but the equipment's mounting dimensions and compatibility requirements should also be checked before installation.

Q3: Is this product a complete CPU module?

No. It is identified as a CPU front panel rather than a processor module. It should not be purchased as a substitute for a CPU that performs controller processing or communication functions.

Q4: What does V2 indicate in the product name?

V2 identifies a particular version or variant. It does not, by itself, establish backward or forward compatibility with other panel versions. Confirm replacement suitability against Siemens documentation.

Q5: Can this front panel replace the 35 mm version?

Do not assume that it can. The 6AG1591-1BA01-2AA0 has a specified CPU width of 70 mm, while other variants may have different physical formats. Match the part number and hardware configuration to the target equipment.

Q6: How do I verify compatibility before ordering?

Check the full part number, the CPU model, the hardware revision, and the panel's mechanical interface. Comparing the original component label with the replacement details is also recommended.

Q7: Does the front panel provide electrical or communication functions?

The product designation alone does not confirm whether it contains electrical contacts, indicators, or other functional elements. Verify its actual construction and function using the relevant technical documentation.

Q8: What should be inspected during replacement?

Inspect the replacement for visible damage and confirm its mounting features and interfaces. Follow the equipment manufacturer's maintenance procedure and observe the required electrical safety precautions.

Q9: What should I do if the panel does not align with the CPU assembly?

Do not force it into position. Recheck the part number, version, width specification, and mounting arrangement. If any discrepancy remains, confirm the correct replacement with the equipment supplier or manufacturer.

Q10: What information helps ensure accurate procurement?

Provide the complete model number, 6AG1591-1BA01-2AA0, the target CPU model, and any available hardware revision details. Photographs of the original label and mounting area can help with identification.
