Product Description: Siemens 6ES7155-6AU01-0BN0 IM 155-6 PN ST

The Siemens 6ES7155-6AU01-0BN0 is the IM 155-6 PN ST interface module from the SIMATIC ET 200SP distributed I/O system. It provides a standard PROFINET connection for linking the ET 200SP station to higher-level controllers (such as SIMATIC S7 CPUs). Designed for high- performance, space- saving installations, this module supports flexible module expansion and efficient data exchange in real-time PROFINET applications.
