Siemens 6ES7288-3AT08-0AA0

Designed Around the S7-200 SMART Platform

The Siemens S7-200 SMART family provides compact automation hardware for machine and process control applications. Analog expansion modules extend the controller with additional field-level measurement capabilities.

For temperature-oriented applications, Siemens identifies the SM AT04 family member as an analog input module for thermocouple signals. This makes correct module identification particularly important when replacing an installed temperature-input module.

Temperature Measurement

Analog temperature acquisition is commonly associated with process and machine monitoring where measured temperature values are required by the control program.

Replacement Searches

Engineers may search for this part number when an installed S7-200 SMART analog module shows abnormal readings, fails to communicate correctly with the controller, or requires planned replacement.

Downtime Exposure

Loss of a required analog measurement can affect temperature monitoring, interlocks or process decisions. In a production machine, an unavailable input can therefore contribute to an unplanned stop.
