S7-400 IM 461-4 receive interface for remote expansion-rack coupling
Siemens 6ES7461-4AA01-0AA0 is the SIMATIC S7-400 IM 461-4 receive interface module used on the expansion-rack side of a remote coupling. Siemens documentation identifies a coupling distance of up to 600 m, without voltage transmission and without K-bus support. It works with the corresponding IM 460-4 send interface in supported S7-400 rack configurations. Procurement checks should compare the complete order number, rack assignment, interface pairing, cable route and installed hardware revision. A similar IM 461 designation does not establish interchangeability because coupling distance, voltage transmission and K-bus capability vary by version.

Compatibility must be evaluated against the installed system configuration. This product should not be treated as a guaranteed direct replacement solely because another item has a similar designation.
The reviewed Siemens S7-400 documentation confirms the exact IM 461-4 order number and its technical role, but it does not state a current lifecycle designation. This page therefore does not classify 6ES7461-4AA01-0AA0 as Active, Discontinued or another lifecycle stage. Verify the installed module revision, rack arrangement and paired IM 460-4 before replacement.
It identifies the Siemens SIMATIC S7-400 IM 461-4 receive interface module for remote expansion-rack coupling.
Siemens documentation states a remote coupling distance of up to 600 m for the IM 461-4 arrangement.
No. The exact IM 461-4 version is documented without voltage transmission and without K-bus support.
Check the paired IM 460-4, rack numbering, cable route, hardware revision and the complete installed configuration.
The exact Siemens documentation reviewed did not state a current lifecycle designation, so no discontinuation conclusion is made here.

Verification, inspection, packaging and logistics support for Siemens 6ES7461-4AA01-0AA0
Our process is designed to give purchasing teams and engineers clear evidence before shipment. Each request is handled around the exact order number, condition requirement and destination rather than a generic product description.
| Service Step | What We Check |
|---|---|
| Model and Suffix Verification | The complete Siemens order number, suffix and visible revision markings are compared with the request. |
| Condition Confirmation | Packaging, seals, enclosure condition and included items are reviewed against the offered condition. |
| Technical Compatibility Review | Available labels, interfaces, connector arrangements and customer-provided system details are compared before approval. |
| Product and Label Photos | Clear inspection images can be supplied for model, revision, connector and condition confirmation. |
| Protective Packaging | Antistatic protection, cushioning and an outer carton are selected for industrial electronic modules. |
| Worldwide Shipping | Available carrier options are coordinated according to destination, package requirements and applicable restrictions. |
| Tracking and Customs Documents | Shipment tracking and standard commercial documents are prepared for the selected route. |
| Warranty and Returns | Written warranty terms and the return authorization process are provided with the commercial agreement. |
| After-Sales Response | Our team follows up on documentation, shipment status and reported product issues. |
Before dispatch, the team checks the visible manufacturer label, order number, revision markings, physical condition and available accessories. Product evidence is compared with the quotation and buyer requirements. Packaging and shipping documents are then prepared for the agreed transport route. This process supports traceable communication without promising unverified quantities or fixed delivery times.
Look for complete company contact details, clear product identification, inspection evidence, written commercial terms and a documented after-sales process.
Confirm the quotation, full order number, product-label photos, condition statement, warranty scope, shipping terms, customs documents and return authorization procedure.
Compare the complete model and suffix, hardware revision, connectors, rack location, power arrangement, signal assignment and project configuration with the installed system.
Warning signs include an incomplete model number, refusal to provide label photos, conflicting specifications, unclear condition descriptions and no explained return process.
Email and WhatsApp details are provided for model verification, inspection requests, packaging coordination and shipping support.
