The Siemens 6ES7288-3AT04-0AA0 is a SIMATIC S7-200 SMART EM AT04 Thermocouple Input Module that provides four thermocouple inputs with 0.1 degree temperature resolution.
- EM AT04
- 4 thermocouple analog inputs
- 24 V DC; 20.4 to 28.8 V DC
- 45 x 100 x 81 mm
In an S7-200 SMART automation station, it integrates four compatible thermocouple signals into signed 16-bit temperature values with cold-junction compensation. 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 ovens, furnaces, heated tooling, exhaust systems, and high-temperature process monitoring.
Important Notice: Use the complete 6ES7288-3AT04-0AA0 code and verify the physical nameplate, current Siemens documentation, signal range, wiring, project, and accessories before installation or replacement.

Thermocouple acquisition
Converts four compatible thermocouple signals into temperature values
High-temperature monitoring
Supplies data for alarms, permissives, and process supervision
Cold-junction compensated measurement
Uses the module's documented compensation and configured thermocouple type
Heat-process equipment
Supports ovens, furnaces, heated tooling, exhaust systems, and high-temperature process monitoring
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-3AT04-0AA0, EM AT04, host system, signal type, wiring, and project from the physical installation.
1
Identity: Match every character of 6ES7288-3AT04-0AA0 and the EM AT04 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
Sensors: Match thermocouple type, polarity, extension cable, cold-junction compensation, filter, and engineering units to Siemens instructions
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
