Siemens 6ES7461-0AA01-0AA0 Interface Module Receiver

Siemens 6ES7461-0AA01-0AA0 is the SIMATIC S7-400 IM 461-0 receiver interface module designed for central coupling without PS transfer, using C-bus transmission to connect modules in a central bus. It supports a central connection distance up to 5 meters, with a maximum cable length between the first and last interface module of 5 meters. The unit measures 25 mm wide, 290 mm high, and 217 mm deep and weighs approximately 610 g, drawing up to 290 mA from the 5 V backplane supply. It functions as the receiver side of the central connection in S7-400 systems, coordinating data flow across IM 461-0 modules in a centralized configuration.
