Product Overview

Official identification

Siemens 6ES7461-3AA01-0AA0 is the SIMATIC S7-400 IM 461-3 receiver interface module.

Primary role

It provides distributed expansion-rack coupling and transfers P-bus and C-bus data over the IM 460-3 / IM 461-3 interface system.

Selection focus

Verify the complete order number, the IM 460-3 pairing, the required bus transmission, and the total cable distance before procurement.

Function

Distributed rack coupling

The IM 461-3 receives the distributed interface link in an S7-400 expansion rack and supports distances up to 102 m.

Bus transfer

The module transfers both P-bus and C-bus data between the central system and the connected expansion rack.

Electrical demand

The interface draws up to 620 mA from the 5 V DC backplane bus and has a maximum power loss of 3.1 W.

Installation

Rack placement

Install the 25 mm wide module in the designated S7-400 expansion rack position. Allow for the full 290 mm height and 217 mm depth.

Cable system

Use the specified IM 460-3 to IM 461-3 connecting cable and keep the first-to-last interface distance within 102.25 m.

Termination

Complete the distributed interface chain with the correct termination arrangement defined for the IM 461-3 system.

Compatibility

Required partner

The IM 461-3 is documented for exclusive operation with the IM 460-3 transmitter interface.

Bus requirement

Choose this version when the expansion rack must receive both P-bus and C-bus transmission.

Mechanical fit

Confirm the expansion rack accepts a 25 x 290 x 217 mm module and that cable routing supports the planned distance.

Compliance

Official catalog identity

The Siemens ST 400 catalog lists 6ES7461-3AA01-0AA0 as the IM 461-3 receiver interface module.

System limits

Compliance with the documented 5 V DC backplane current, power loss, bus pairing, and maximum cable distance is essential for the intended configuration.

Procurement control

Do not assign approvals or environmental ratings that are not stated for this exact article in the selected official product data.

FAQ

1	How can I verify that the quotation is for the exact 6ES7461-3AA01-0AA0? Require the full order number on the Siemens label and quotation, and confirm that the description identifies an IM 461-3 receiver interface for distributed expansion up to 102 m with C-bus transmission.
2	How can I distinguish a new IM 461-3 module from used or refurbished stock? Request current photos of the front label, 5 V backplane connector area, cable interface, housing, mounting points, seals, and packaging. Check for dust, wear, bent pins, scratches, rework, and mismatched labels.
3	How should I assess whether the supplier is legitimate and reliable? Verify the legal company identity, invoice details, traceable contact information, and ability to provide time-stamped photos of the same 6ES7461-3AA01-0AA0 unit. The quotation should identify IM 461-3 rather than a generic S7-400 interface.
4	Which engineering data must be checked before ordering? Confirm the S7-400 expansion-rack arrangement, the paired IM 460-3, the P-bus and C-bus requirement, the maximum 102.25 m interface distance, 5 V DC backplane demand up to 620 mA, and the 25 x 290 x 217 mm module envelope.
5	What physical evidence should be requested before payment? Ask for time-stamped images of every side, the complete label, connector pins, housing edges, packaging, and serial or batch markings. A continuous video should show the same labeled module and its interfaces without cuts.
6	Can a similar IM 461 or another suffix replace 6ES7461-3AA01-0AA0? Do not assume interchangeability. This article is the IM 461-3 receiver for distributed coupling and is documented for exclusive use with IM 460-3; bus transmission, cable system, dimensions, and the exact suffix must all match.
