Central System Expander for S7-400 Racks
Extend the capabilities of your SIMATIC S7-400 PLC with the 6ES7460-0AA01-0AB0 Send IM 460-0. This interface module allows you to connect an expansion rack (UR) to a central controller rack, increasing the total number of available I/O modules. It transfers the C-bus (communication bus) for seamless data exchange.
Core Function & Benefit
Cost-Effective Expansion: Add more I/O modules without needing a separate, expensive CPU, perfect for large machines with many sensors and actuators.
Simplified System Design: Organize your I/O by separating groups of modules into different racks for cleaner wiring and maintenance.
Seamless Communication: The connected expansion rack operates as if its modules are in the central rack, with fast and transparent data transfer via the C-bus.
Complete Technical Data
Brand: Siemens
System: SIMATIC S7-400
Module Type: Send Interface Module IM 460-0
Full Model Code: 6ES7460-0AA01-0AB0
Function: For central coupling without 5V power transfer.
Transferred Bus: C-Bus (Communication Bus) only.
Power from Central Rack: 5V DC, max. 140 mA.
Maximum Power Loss: 700 mW.
Maximum Cable Length: 5 meters between send and receive modules.
Required Accessory: Termination plug 6ES7461-0AA0-7AA0 (for empty slots in the rack).

Installation & Compatibility Guide
Insert the Send IM 460-0 into the last slot (slot 21) of your central controller rack (CR). In the expansion rack (UR), install the matching Receive IM 461-0 module. Connect the two modules using a specialized interface cable (ordered separately). The expansion rack must have its own power supply module (PS) since the IM 460-0 does not transfer 5V power.
Warranty & Delivery
This interface module is covered by our standard 12-month warranty. We ensure rapid dispatch via global carriers FedEx, UPS, and DHL.
Essential FAQs
Q: What is the difference between IM 460-0 and IM 460-1?
A> The IM 460-0 (this module) transfers only the C-bus. The IM 460-1 transfers both the C-bus and 5V power to the expansion rack, which can power some low-current modules.
Q: How many expansion racks can I connect?
A> You can connect up to 4 expansion racks with a total of up to 21 additional I/O modules, depending on your CPU model and configuration.
Q: Does the expansion rack need its own CPU?
A> No. The expansion rack is controlled by the CPU in the central rack. The interface modules make the I/O in the expansion rack appear local to the main CPU.
Q: What cable do I need to connect the racks?
A> You need a specific interface cable, such as the 6ES7468-1... series. The length must not exceed the 5-meter maximum specified for reliable communication.
Q: Can I mix different interface module types in one system?
A> No. The Send and Receive module pair must be of the same type (e.g., IM 460-0 with IM 461-0). They form a matched pair for a specific connection.
