Description

Siemens 6ES7288-3AT04-0AA0 is a SIMATIC S7-200 SMART SM AT04 analog input module designed for four thermocouple channels. It operates from a nominal 24 V DC supply within a permissible range of 20.4 to 28.8 V DC and provides a maximum measurement resolution of 16 bits including sign for supported thermocouple signals.

The module is intended for temperature acquisition in S7-200 SMART automation systems where four thermocouple measurement points are required. It draws approximately 30 mA from the 24 V DC user supply and about 70 mA from the 5 V backplane bus under typical conditions, with a typical power loss of 1.5 W.

The SM AT04 is intended for four-channel thermocouple temperature acquisition in compatible S7-200 SMART control systems. Application accuracy depends on the selected thermocouple type, polarity, compensation wire, ambient stability, grounding, shielding, filtering, and controlled Siemens installation requirements.

Siemens 6ES7288-3AT04-0AA0 is an SM AT04 thermocouple analog input expansion module for the SIMATIC S7-200 SMART platform. Confirm a compatible S7-200 SMART CPU, available expansion position, SM Bus power, 24 V DC supply, terminal hardware, mechanical space, supported project software, and current Siemens documentation before installation.

Do not substitute the module solely by channel count. Match the complete 6ES7288-3AT04-0AA0 article number, four-channel thermocouple function, resolution, diagnostics, connector assignment, supply range, dimensions, power consumption, module position, and configured thermocouple parameters.

Siemens lists 6ES7288-3AT04-0AA0 as an active PM300 product in the current product interface. Ordering availability, certificates, delivery time, and lifecycle status should be reconfirmed against the current Siemens listing when the exact article is procured.

For replacement, preserve the complete article number and compare the CPU family, firmware, module position, channel configuration, thermocouple types, diagnostics, terminal wiring, mechanical dimensions, power budget, and project parameters. Back up the hardware configuration before exchanging the module.

Technical notes

Use only supported thermocouple types and follow the current Siemens S7-200 SMART documentation for channel configuration, polarity, wiring, grounding, power supply, installation, and commissioning.

FAQs

  • How many thermocouple inputs does the module provide?

    +
    The SM AT04 provides four analog input channels for thermocouple measurement.
  • What supply voltage is required?

    +
    The module uses a rated 24 V DC supply with a permissible range of 20.4 to 28.8 V DC.
  • What is the maximum measurement resolution?

    +
    The official Siemens technical data specifies a maximum resolution of 16 bits including sign.
  • Can the channels be used for voltage, current, RTD, or resistance inputs?
