SIMATIC ET 200SP article 6ES7134-6FF00-0AA1 is the AI 8xU BA analog input module. It acquires eight voltage channels in a narrow distributed-I/O format and presents sixteen bytes of input data to the station.

The module uses BU type A0 or A1, carries color code CC02 and provides 16-bit conversion with module diagnostics. Current hardware information identifies FS23 or later and firmware V2.0.0 with firmware-update capability.

• Converts eight field voltage signals into digital process values for an ET 200SP station.
• Occupies a compatible A0 or A1 BaseUnit and uses the module-specific CC02 identification code.
• Transfers up to sixteen bytes of analog input data to the controller.
• Reports module-level diagnostics for commissioning and maintenance.
• Supports firmware updates while remaining dependent on the station interface module and engineering configuration.

• Use only BU type A0 or A1 as specified for the module connection concept.
• The BA voltage-input module is not interchangeable with current, RTD or thermocouple input variants without wiring and configuration changes.
• Current engineering data identifies TIA Portal V21, STEP 7 V5.7 SP3, GSD revision 3 or 5 and GSDML V2.45 contexts.
• Match the configured measuring range, channel activation and diagnostic settings to the original project.
• Preserve the terminal assignment and the module-specific color-coded label during service.

• Distributed acquisition of eight analog voltage signals in an ET 200SP station.
• Compact cabinets requiring high channel density and a narrow I/O module footprint.
• Machine and process measurement tasks using configured voltage ranges.
• Expansion of an existing ET 200SP station with the required A0 or A1 BaseUnit.
• Like-for-like replacement of an AI 8xU BA after channel parameters and wiring are documented.

What signal type does 6ES7134-6FF00-0AA1 measure?

It is an eight-channel analog voltage input module.

Which BaseUnits are compatible?

The module is designed for ET 200SP BU type A0 or A1.

How much input address space can it use?

The maximum module address space is sixteen bytes.

Does the module support firmware updates?

Yes. Firmware updating is supported for the documented hardware and firmware context.

Can it directly replace an eight-channel current input module?

No. The electrical input type, wiring and configured measuring ranges must match the voltage-input BA module.

What should be verified after replacement?

Verify the BaseUnit, channel wiring, measuring ranges, diagnostics, process values and controller address assignment.
