Siemens 6ES7460-0AA01-0AB0 SIMATIC S7-400 IM 460-0 Send Interface PLC Connection Module

The Siemens 6ES7460-0AA01-0AB0 is a SIMATIC S7-400 IM 460-0 send interface module that links a central rack to an expansion rack over a cable up to 5 m long. It carries the C-bus across that link, so the expansion rack keeps full cross-rack configuration and diagnostics, but it does not transfer the power-supply bus, so the expansion rack needs its own supply.

Selection Notes

Carrying the C-bus is what sets the IM 460-0 apart from the IM 460-1: it keeps cross-rack diagnostics and configuration data available to the expansion rack, at the cost of needing its own power supply there since the module does not transfer PS. Pick it over the IM 460-1 when the expansion rack needs full C-bus visibility for diagnostics, and over the longer-distance IM 460-3 variant when the rack-to-rack run stays within the 5 m this module covers. It always pairs with an IM 461-0 receiver module and the 6ES7461-0AA0-7AA0 termination plug on the far end of the cable run.
