The Siemens 6ES7288-3AM03-0AA0 is a SIMATIC S7-200 SMART EM AM03 Analog I/O Module that provides two analog inputs and one analog output in one 45 mm module.
- EM AM03
- 2 analog inputs and 1 analog output
- 24 V DC; 20.4 to 28.8 V DC
- 45 x 100 x 81 mm
In an S7-200 SMART automation station, it acquires two analog process signals and returns one analog command signal through a single expansion module. It works with the exact CPU, expansion-bus or signal-board interface, wiring, field devices, and project configuration specified for the complete article number. It is applied in small closed-loop skids, single-axis drive references, dosing systems, and compact process machines.
Important Notice: Use the complete 6ES7288-3AM03-0AA0 code and verify the physical nameplate, current Siemens documentation, signal range, wiring, project, and accessories before installation or replacement.

Important Notice: These are two separate Apter Power documents prepared from the manufacturer-published Siemens information named in each document. Confirm the physical nameplate, current Siemens documents, and host-system requirements before installation or replacement.
Closed-loop control
Acquires process feedback and returns analog commands through one module
Skid instrumentation
Combines transmitter inputs with valve or drive references
Multi-variable coordination
Supports small closed-loop skids, single-axis drive references, dosing systems, and compact process machines
Panel-density improvement
Reduces separate analog input/output module count where the channel total fits
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-3AM03-0AA0, EM AM03, host system, signal type, wiring, and project from the physical installation.
1
Identity: Match every character of 6ES7288-3AM03-0AA0 and the EM AM03 marking to the physical nameplate and project
2
Host and power: Verify 24 V DC; 20.4 to 28.8 V DC; isolate all energy sources before insertion, removal, or wiring
3
Signals: Configure every channel for the documented signal type and range; observe polarity, reference, load, and diagnostic limits
4
Cabling: Follow Siemens terminal, shielding, grounding, separation, and maximum cable-length instructions
5
Commissioning: Verify addresses and scaling, energize one circuit group at a time, test fail-safe behavior, and record results
