Siemens 6ES7288-3AE04-0AA0 Four-Channel Analog Input Module
Four differential voltage-or-current inputs with channel modes selected in pairs for SIMATIC S7-200 SMART.
Product Overview
Siemens 6ES7288-3AE04-0AA0 is the SIMATIC S7-200 SMART EM AE04 analog input expansion module. Its four differential channels accept voltage or current signals, with the mode selected in groups of two.
The module is non-isolated from field side to logic. Signal range, pair configuration, common-mode conditions, shield routing and the required gold connector must be checked as one installation boundary.
Technical Data
Functions
Paired channel configuration
Each two-channel group shares the selected voltage-or-current mode, making the pair assignment part of the project record.
Signal conditioning choices
Configurable smoothing and noise rejection support the approved measurement environment.
Range supervision
Overflow, underflow and low 24 V DC diagnostics support commissioning and maintenance checks.
Differential acquisition
Separate positive and negative terminals are provided for every analog input channel.
Applications
Process transmitters delivering supported voltage or current signals.
Machine measurements that require four differential analog channels.
Like-for-like service where pair modes and scaling records are available.
Service Planning
Project capture
Export channel ranges, smoothing, noise rejection and engineering-unit scaling.
Loop review
Identify 2-wire or 4-wire transmitters, field power and shield termination.
Controlled transfer
Use the documented gold connector and preserve the positive/negative channel pairing.
Acceptance
Validate zero, span, raw counts, diagnostics and alarm behavior for each loop.

FAQ
Why must channel pairs be documented for 6ES7288-3AE04-0AA0?
Voltage or current mode is selected in groups of two, so a replacement must reproduce the pair assignment before loop testing.
Can 6ES7288-3AE04-0AA0 be treated as an isolated analog input module?
No. Review grounding, common-mode voltage, shield routing and transmitter power because the field side is not isolated from logic.
Which connector detail matters when ordering 6ES7288-3AE04-0AA0?
Siemens specifies gold connectors for the analog module, so the connector identity should be confirmed with the module and terminal photographs.
What loop records reduce commissioning risk for 6ES7288-3AE04-0AA0?
Provide channel range, pair mode, transmitter type, field-power arrangement, shield termination, scaling and alarm settings.
How should 6ES7288-3AE04-0AA0 be accepted after exchange?
Inject controlled values across each configured range and verify raw data, engineering units, diagnostic response and the process alarm chain.
