Siemens 6ES7195-0BH30-0XA0 Bus Module for SIMATIC ET 200M

The Siemens 6ES7195-0BH30-0XA0 (6ES7195-0BH30-0XA0) is a SIMATIC ET 200M active bus module designed for modular distributed I/O configurations in industrial automation systems. Designed for use with Siemens SIMATIC S7-300 automation platforms and ET 200M interface stations, this bus module mounts directly onto an active DIN rail to establish backplane communication between interface modules and connected I/O components. It accommodates two 40 mm wide signal modules or one 80 mm wide module, enabling hot-swapping capabilities that allow maintenance technicians to replace faulty I/O modules under voltage while the system remains in RUN mode without interrupting industrial process operations. Engineered for reliable signal distribution and backplane power interconnection, the unit serves as an essential hardware component for distributed control architectures across automotive manufacturing, water treatment, chemical processing, and material handling applications. It provides mechanical guidance and secure electrical contact for connected modules, facilitating fast maintenance, system upgrades, and line expansions. The module functions seamlessly within compatible ET 200M distributed I/O racks, ensuring stable communication across PROFIBUS DP or PROFINET industrial networks.
