Long-Distance Rack Coupling for Distributed I/O Systems
Distribute your S7-400 I/O over large areas with the Siemens 6ES7460-3AA01-0AB0 Send IM 460-3. This robust interface module enables a remote expansion rack up to 102 meters away from the central controller. It's the ideal solution for large machines, production lines, or plants where sensors and actuators are spread out.

Transferred Bus: C-Bus (Communication Bus).
Maximum Separation Distance: 102.25 meters between interface modules.
Power Consumption (Backplane): 5V DC, max. 1,550 mA.
Maximum Power Loss: 7,750 mW (7.75 W).
Required Termination: Plug 6ES7461-3AA0-7AA0.
Module Dimensions: 25 mm (W) x 290 mm (H) x 280 mm (D).

Installation & System Setup
Install the Send IM 460-3 in the central rack (CR). Install the matching Receive IM 461-3 in the remote expansion rack (UR). Connect them using a specialized, shielded interface cable designed for long distances (order separately). The remote rack must have its own power supply module (PS) as 5V power is not transferred. Ensure the total cable length does not exceed 102.25 meters for reliable operation.
Warranty & Shipping
This product is covered by a 12-month warranty. We ship promptly using reliable express services: FedEx, UPS, and DHL.
Expert FAQs
Q: What is the main difference between the IM 460-3 and the IM 460-0?
A> The key difference is distance. The IM 460-0 is for local expansion (max 5m), while the IM 460-3 is specifically designed for long-distance distributed I/O (up to 102m).
Q: Can I use standard Ethernet or PROFIBUS cable for the connection?
A: No. You must use the specified Siemens interface cable (e.g., 6ES7468-3... series) designed for the electrical characteristics required for reliable long-distance C-bus transfer.
Q: How many remote racks can I connect with one IM 460-3?
A> One Send IM 460-3 can connect to one Receive IM 461-3, forming a point-to-point link to a single remote expansion rack.
Q: Does the signal delay over 100 meters affect performance?
A> The system is engineered to handle the propagation delay over the specified maximum distance. I/O update times will be slightly slower than local I/O but are predictable and suitable for most process and machine control applications.
Q: What accessories are required for a complete setup?
A> You need this Send IM 460-3, a Receive IM 461-3, the correct length of interface cable (6ES7468-3...), and a termination plug (6ES7461-3AA0-7AA0) for the last slot in the remote rack.
