Siemens 6ES7460-0AA00-0AB0 Interface Module S7-400

Siemens 6ES7460-0AA00-0AB0 is a SIMATIC S7-400 interface module (IM 460-0) that provides centralized coupling for expansion I/O within a S7-400 automation system. It is designed for central connection between the CPU and I/O modules over short distances, with typical configurations supporting lengths up to about 5 meters between IM 460-0 units, enabling compact, robust layouts. The IM 460-0 family supports bus-transfer options that link the central interface to other components in the S7-400 network, such as K-bus or C-bus paths, depending on installation and wiring, making it suitable for extending controller I/O or bridging multiple modules in centralized architectures. As a standard part of Siemens' SIMATIC S7-400 product line, the 6ES7460-0 series is used in many industrial applications for reliable, modular expansion of centralized automation backbones, delivering a straightforward path to scale I/O without altering core CPU configuration.
