Siemens 6ES7288-3AM03-0AA0 EM AM03 Mixed Analog I/O Module
A compact EM AM03 signal module combining two analog inputs with one analog output for S7-200 SMART stations.
Overview
Siemens 6ES7288-3AM03-0AA0 is the SIMATIC S7-200 SMART EM AM03 module with two analog inputs and one analog output. The input pair supports documented voltage or current configuration, including ±10 V, ±5 V, ±2.5 V and 0–20 mA ranges.
Input ranges are selected in the approved group configuration, while the output must retain its own voltage or current setting, scale and connected-load documentation.
The complete article number differentiates this compact 2-input/1-output arrangement from the larger AM06 and from input-only or output-only S7-200 SMART modules.
Specifications
Features
Mixed signal footprint
Two measurements and one command channel share one 45 mm module position.
Selectable input ranges
The input pair can be configured for documented bipolar voltage or 0–20 mA current service.
Engineering scaling
Raw values are converted in the project to the units required by the connected process.
Gold-plated connectors
The documented connector execution is retained as part of the exact module identity.
Applications
Compact closed-loop task
Two measurements and one manipulated output in a small machine or process station.
Signal conditioning panel
Bipolar voltage or current inputs with one matching documented control output.
Service spare
Like-for-like AM03 replacement with group range, output mode and scaling preserved.
Lifecycle
Document
Archive both input ranges, output mode, scales, external 24 V supply and terminal map.
Protect
Isolate controller and field supplies, preserve shields and confirm the approved load connection.
Commission
Inject known inputs, command the output through safe points and compare every engineering value.

FAQ
Can 6ES7288-3AM03-0AA0 be replaced by the six-channel AM06?
Not without engineering review. 6ES7288-3AM03-0AA0 has two inputs and one output; hardware layout, address use and project mapping differ.
What range evidence is needed for 6ES7288-3AM03-0AA0?
Record the configured input group range, output voltage/current mode, raw scaling, engineering units and terminal wiring.
Why must the external 24 V load be reviewed for 6ES7288-3AM03-0AA0?
Output loading changes the module 24 V current requirement, so the field supply budget must include the actual command circuit.
How should the two inputs on 6ES7288-3AM03-0AA0 be tested?
Inject traceable values in the configured range and verify polarity, raw counts, engineering conversion and out-of-range diagnostics.
What proves the 6ES7288-3AM03-0AA0 output is correctly restored?
Command several safe setpoints, measure the terminal signal and confirm the connected device response and configured fallback behavior.
