          PRODUCT DESCRIPTION

          Sixty onboard digital points with expandable ST60 control

          Siemens 6ES7288-1ST60-0AA1 is the CPU ST60 DC/DC/DC controller in the S7-200 SMART family. It combines thirty-six digital inputs, twenty-four sourcing transistor outputs and 30 KB of program memory, providing a sixty-point base for an expandable control station.

          Ethernet and RS485 provide network and serial communication alongside the local I/O. Expansion modules and a signal board can extend the standard CPU, while separate sensor-power, expansion-bus and output-group ratings define the electrical resources available to the configured station.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          S7-200 SMART CONTROL

          A sixty-point station with distinct power and communication resources

          The ST60 places thirty-six digital inputs and twenty-four transistor outputs in the CPU itself, with 30 KB reserved for program memory. Six expansion modules and one signal board can extend the standard configuration, subject to the project arrangement and the available electrical budget.
          Electrical loading is divided among separate resources. The CPU provides a 1.4 A expansion-bus supply and a 300 mA sensor-power output, while the transistor outputs are limited to 0.5 A per point and 6 A per common. These ratings are not interchangeable.
          Ethernet and RS485 allow network and serial connections within the documented CPU architecture. Firmware remains important: Siemens describes additional ST60 motion resources and enlarged data-memory ranges for V2.8. Match those capabilities to the actual unit and engineering project before relying on them.

          Features:

          • 36/24 onboard digital I/O
          • Separate bus and sensor budgets
          • Firmware-aware network integration
          The Siemens 6ES7288-1ST60-0AA1 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
          INTERCHANGEABILITY

          Verify the complete replacement identity before commissioning

          Read the complete order number and DC/DC/DC designation before selecting the spare. ST60, SR60 and CR60 variants have different output technologies, supply arrangements and expansion facilities even when their total I/O counts match. Neither housing size nor a sixty-point description establishes equivalence.
          Keep the engineering project and identify the installed firmware, configured motion resources and memory use. Siemens lists release-specific additions and downgrade restrictions for this AA1 CPU. An order-number match therefore does not by itself prove that an existing project can be transferred without review.
          Compare the exact ST60 terminal table with the installation drawings, including its continuation rows. Check the special input-channel conditions, transistor common groups, connected loads and STOP settings. Output overload protection is not provided internally, so the surrounding protection design remains part of the replacement assessment.

          Features:

          • Full AA1 identity and firmware
          • Exact transistor terminal mapping
          • Loading and STOP-state review
          The Siemens 6ES7288-1ST60-0AA1 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7288-1ST60-0AA1

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • What distinguishes this ST60 from a sixty-point relay CPU?

            This ST60 uses a DC supply and sourcing MOSFET transistor outputs. The SR60 variant uses relay contacts and a different supply arrangement; an equal I/O count does not establish electrical interchangeability.

          • Does the 0AA1 suffix establish the installed firmware?

            No. Siemens identifies this order number across several firmware releases. Confirm the supplied unit and project; the V2.8 release adds memory and ST60 motion functions and cannot be downgraded to V2.7 or earlier.

          • Why is a single total-memory figure not used here?

            Program memory is documented as 30 KB. Variable and retentive memory depend on the applicable firmware documentation; V2.8 increases those areas, so a combined headline figure can hide a version difference.

          • Are all thirty-six inputs electrically identical?

            No. The ST60 table gives special signal thresholds for I0.0 through I0.3 and different filtering and cable conditions for designated channels. Use the exact channel table when checking the existing signals.

          • Can the sensor supply rating be used as the output loading rating?

            No. The 300 mA sensor supply, 1.4 A expansion-bus resource, 0.5 A output-point limit and 6 A output-common limit describe different circuits. Each must be assessed independently.

          • Does this CPU include internal transistor-output overload protection?

            The manufacturer output table states that overload protection is not provided. Review the existing circuit protection, connected load and common-group current before replacement; the output count alone is insufficient.

          • Which terminal drawing applies to the AA1 transistor version?

            Use the exact ST60 6ES7288-1ST60-0AA1 drawing and its complete connector table. The last two terminal-table rows continue on the following page, which also contains an unrelated SR60 relay drawing.

          • Are Ethernet and serial communication both available?

            Yes. The CPU has one 10/100 Mbit/s Ethernet port and one RS485 interface. Communication roles and project settings must still match the installed firmware and network rather than being inferred from the connectors alone.
