The 6ES7461-3AA01-0AA0 is a high-performance receiver module from Siemens. It belongs to the SIMATIC S7-400 family and serves distributed coupling applications. Unlike shorter-range versions, this IM 461-3 model reaches up to 102.25 meters. Additionally, it includes full C-bus support for advanced communication.
This module draws 620 mA from the 5 V DC backplane bus. Its maximum power loss is 3,100 mW, which reflects its extended capabilities. You need the dedicated termination plug 6ES7461-3AA0-7AA1 for proper operation. Use this receiver when your I/O racks are far from the central controller.
The Siemens 6ES7461-3AA01-0AA0 operates on a 5 V DC supply from the backplane. Its input current is 620 mA max, significantly higher than short-range models. Power loss reaches 3,100 mW max due to the longer driving distance.
Furthermore, the hardware configuration supports a remarkable cable length of 102.25 meters between the first and last interface module. This distance makes distributed coupling practical for large factories. The module also features C-bus functionality, which enables communication with additional intelligent peripherals.
Note that the connection method requires a specific termination plug: 6ES7461-3AA0-7AA1. Do not substitute other terminators, as the IM 461-3 has unique bus impedance characteristics.
The C-bus on 6ES7461-3AA01-0AA0 allows communication with intelligent I/O modules. This includes FM (function module) and CP (communication processor) devices on the remote rack. Short-range IM 461-1 models lack this C-bus capability entirely.
For instance, you can place a CP 441 communication processor in a remote rack with this receiver. The C-bus carries data between that CP and the central CPU. Therefore, distributed coupling becomes truly flexible and powerful.
Dimensions remain compact despite the extended range: 25 mm width, 290 mm height, and 280 mm depth. The 6ES7461-3AA01-0AA0 weighs approximately 620 g, with a gross weight of 0.70 kg including packaging. Its slim 25 mm width matches other S7-400 modules for seamless rack integration.
Meanwhile, this receiver module is built for industrial environments. It handles vibration, temperature fluctuations, and electromagnetic interference typical in factories. You can deploy it in automotive plants, warehouses, or process facilities without concern.
First, mount the Siemens 6ES7461-3AA01-0AA0 on a standard S7-400 DIN rail. Ensure the backplane bus connectors align with adjacent modules. Next, connect the dedicated cable between this receiver and its transmitter module. Keep the total distance within the 102.25 m maximum limit.
Then, install the termination plug 6ES7461-3AA0-7AA1 at the physical end of the bus segment. This step is mandatory for the IM 461-3. Without proper termination, signal reflections will corrupt communication.
Finally, verify the 5 V DC backplane supply can deliver 620 mA to this module. Calculate your total backplane load before powering up. Configure your hardware in STEP 7, enabling C-bus features as needed.
