Product Overview
The Siemens 6ES7460-1BA01-0AB0 is a Send IM 460-1 interface module for the SIMATIC S7-400 automation system. Designed for central coupling with power supply transfer, this module supports reliable data exchange without the C bus. Its compact footprint and low power consumption make it a cost-effective choice for expanding or upgrading S7-400 racks.
With a power loss of only 425 mW and an input current of 85 mA from the 5 V DC backplane bus, the 6ES7460-1BA01-0AB0 minimizes energy waste and heat generation. This efficiency directly reduces operational costs and extends component life, aligning with long-term ROI goals.

Industry Applications
The Siemens 6ES7460-1BA01-0AB0 serves central coupling tasks in S7-400 systems. Typical applications include:
- Connecting multiple racks in medium to large automation lines
- Transferring power and signals between local and remote I/O stations
- Integrating safety or redundant controller configurations
Its low power loss (425 mW) translates to less heat load in cabinets, reducing cooling requirements and improving overall system reliability.
Installation & Setup Guidance
Install the Siemens 6ES7460-1BA01-0AB0 into any free slot of the S7-400 rack. Ensure the backplane bus supplies 5 V DC. The maximum cable length between the first and last interface module is 1.5 m. Use shielded cables for signal integrity. No additional tooling is required; the module locks into place with built-in guides.
Maintenance & Reliability
This interface module requires minimal maintenance. Periodically check for:
- Secure seating in the rack
- Clean, dust-free connector surfaces
- Proper cable strain relief
The Siemens 6ES7460-1BA01-0AB0 is built for continuous industrial duty. Its low power dissipation (425 mW) reduces thermal stress, contributing to a longer service life and fewer replacements.
Selection Guide & Purchasing Advice
Before ordering the Siemens 6ES7460-1BA01-0AB0, verify compatibility with your existing S7-400 CPU and backplane. Confirm that your rack has a free slot and that the power supply can deliver the required 85 mA at 5 V DC.
