6ES7461-1BA01-0AA0 Siemens SIMATIC S7-400 Interface Module
Product Introduction
The 6ES7461-1BA01-0AA0 belongs to Siemens’ renowned SIMATIC S7-400 series. This interface module works as an IM 461-1 receiver for central coupling applications. It supports PS transfer but does not include a C bus. You can use it to connect remote I/O racks to a central controller reliably.
For instance, this module draws only 120 mA from the 5 V DC backplane bus. Its maximum power loss is just 600 mW, which keeps heat low inside the cabinet. Additionally, the cable length between the first and last interface module can reach up to 1.5 meters. This flexibility simplifies system layout in crowded control panels.
Technical Specifications
The Siemens 6ES7461-1BA01-0AA0 operates with a 5 V DC supply voltage from the backplane. Its current consumption is 120 mA max, ensuring low energy use. Power loss stays at 600 mW max, which reduces cooling requirements.
Furthermore, the hardware configuration allows a maximum cable length of 1.5 meters between the first and last interface module. This distance supports typical central coupling setups without signal degradation. The module has no C bus, so it focuses purely on receiver functions for PS transfer.
Mechanical and Environmental Data
Dimensions are compact: 25 mm width, 290 mm height, and 280 mm depth. The 6ES7461-1BA01-0AA0 weighs approximately 610 g, and the gross weight with packaging is 0.68 kg. Its slim 25 mm width saves valuable rail space in crowded cabinets.
Meanwhile, the module is built for industrial environments. It operates reliably within standard S7-400 temperature and humidity ranges. Therefore, you can deploy it in factories, process plants, and automation cells without concern.
Installation Guidelines
First, mount the 6ES7461-1BA01-0AA0 on a standard S7-400 DIN rail. Ensure the backplane bus connector aligns correctly with adjacent modules. Next, connect the cable between the IM 461-1 receiver and its corresponding transmitter module. Keep the cable length within the 1.5 m maximum limit.
Then, verify the 5 V DC supply from the backplane is stable. The module draws only 120 mA, so power budgeting is straightforward. Finally, configure your hardware in STEP 7. Assign parameters to match your central coupling with PS transfer requirements.
