- Description
The Siemens 6ES7460-1BA01-0AB0 is a SIMATIC S7-400 IM 460-1 send interface module that links a central rack to an expansion rack over a cable up to 1.5 m long, transferring the power-supply bus so the expansion rack does not need its own supply. It does not carry the C-bus, so cross-rack diagnostics stay limited to the central rack.

Selection Notes
The IM 460-1 trades C-bus visibility for power-supply transfer: the expansion rack runs off the central rack's supply instead of needing its own, but loses the shared configuration and diagnostics data the IM 460-0 carries. Pick it over the IM 460-0 when eliminating a second power supply on the expansion rack matters more than cross-rack diagnostics, and note that its 1.5 m maximum cable run is shorter than the C-bus variant's. It pairs with an IM 461-1 receiver module on the expansion rack.
