Description

Siemens 6ES7288-3AT08-0AA1 is a SIMATIC S7-200 SMART G2 EM AT08 thermocouple expansion module with eight isolated input channels. Each channel can be configured for a supported thermocouple type or voltage measurement, and temperature values are resolved to 0.1 degree units.

The module provides 15-bit-plus-sign voltage conversion, cold-junction compensation, selectable noise rejection, wire-break diagnostics, and channel-to-channel isolation. Reliable measurement requires the correct thermocouple type, polarity, compensation method, terminal wiring, grounding, filter selection, warm-up time, and STEP 7-Micro/WIN SMART V3 configuration.

  • Environmental test-chamber temperature control
The EM AT08 is intended for temperature or millivolt measurement using independently configurable channels. Application accuracy depends on the correct thermocouple type, polarity, cable material, cold-junction compensation, ambient stability, filter setting, shielding, grounding, and controlled Siemens installation requirements.

Siemens 6ES7288-3AT08-0AA1 is an EM AT08 expansion module for the SIMATIC S7-200 SMART G2 platform. Confirm use with a compatible G2 CPU, STEP 7-Micro/WIN SMART V3 project, available SM-bus power, correct terminal hardware, mechanical space, and supported firmware before installation.

Do not substitute the module solely by channel count. Match the complete article number, eight-channel thermocouple function, supported sensor types, voltage mode, isolation, cold-junction compensation, diagnostics, filter settings, wiring arrangement, dimensions, power consumption, and project configuration.

Siemens identifies 6ES7288-3AT08-0AA1 as the EM AT08 eight-channel thermocouple expansion module in the current SIMATIC S7-200 SMART G2 system documentation. Confirm current Siemens lifecycle status, certificates, firmware requirements, ordering availability, and delivery information when procuring the exact article number.

For replacement, preserve the complete 0AA1 article number and compare CPU generation, firmware, module position, channel configuration, thermocouple types, isolation, diagnostics, cold-junction behavior, terminal wiring, mechanical dimensions, power budget, and project parameters. Back up the hardware configuration before exchanging the module.
