          PRODUCT DESCRIPTION

          6ES7403-1TA01-0AA0 ER1 Eighteen-Slot Expansion Rack

          Siemens 6ES7403-1TA01-0AA0 is the ER1 expansion rack for SIMATIC S7-400. It provides eighteen single-width positions and a P-bus backplane for the documented signal-module expansion arrangement. The manufacturer identifies this rack for signal modules rather than as a general-purpose central CPU rack.

          The rack supports the specified arrangement with two pluggable redundant power supplies. Its available positions must be allocated with the actual power and interface hardware required by the S7-400 station design; eighteen positions do not imply eighteen signal modules in every configured rack. The compatible expansion interface and host arrangement determine how the rack is connected to the central station.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

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

          SYSTEM INTEGRATION

          Integrate 6ES7403-1TA01-0AA0 within SIMATIC S7-400

          Use ER1 as the documented S7-400 expansion rack and select the supported expansion interface and host connection. The P bus serves the signal-module arrangement. Do not assume that CPU or communication modules intended for a different rack architecture are supported here.
          Allocate the eighteen single-width positions to the actual station layout, including the required power-supply and interface hardware. If redundant supplies are used, follow the specified two-supply arrangement and the applicable module compatibility rules. Reserve positions according to the selected hardware widths.
          Mount the rack under the S7-400 mechanical and grounding instructions, retaining the required clearances and secure backplane connections. Calculate the station demand using the fitted modules and supply arrangement. Check the host expansion configuration before commissioning the signal modules.

          Features:

          • Maximum single-width positions: 18
          • Backplane bus: P bus
          • SIMATIC S7-400
          Use 6ES7403-1TA01-0AA0 only within the documented SIMATIC S7-400 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7403-1TA01-0AA0 within SIMATIC S7-400

          Identify 6ES7403-1TA01-0AA0 and record the installed slot map, expansion interface and power-supply arrangement. Preserve the ER1 expansion-rack role and P-bus configuration. Another eighteen-position S7-400 rack can have a different backplane function.
          Isolate the station according to the S7-400 service procedure and label each module position before removal. Preserve the expansion cables, grounding points and redundant-supply connections. Inspect backplane connectors and mechanical mounting for damage or contamination.
          Reinstall the modules in the documented positions and verify the expansion interface and power status. Confirm recognition of each signal module and compare the configured addresses with the saved station project. Restore process I/O only after station diagnostics are satisfactory.

          Features:

          • 6ES7403-1TA01-0AA0 complete order code
          • Power-supply arrangement: 2 redundant power supplies pluggable
          • Retain the documented SIMATIC S7-400 connection arrangement
          Use 6ES7403-1TA01-0AA0 only within the documented SIMATIC S7-400 arrangement and applicable installation instructions.

            Yes. The product description for 6ES7403-1TA01-0AA0 specifies two pluggable redundant power supplies in the applicable configuration.

          • Do eighteen positions on 6ES7403-1TA01-0AA0 always mean eighteen signal modules?

            No. The slot allocation of 6ES7403-1TA01-0AA0 must include the required power and interface hardware and the width of each fitted module.

          • What must be preserved when replacing 6ES7403-1TA01-0AA0?

            Record the slot map, expansion interface, supply arrangement and host configuration before exchanging 6ES7403-1TA01-0AA0.

          • What should a distributor retain when quoting 6ES7403-1TA01-0AA0?
