Siemens 6ES7 195-7HB00-0XA0 Simatic S7 Bus Module

Siemens 6ES7195-7HB00-0XA0 SIMATIC ET 200M Active Bus Module (BM 240) for holding two 40 mm-wide I/O modules (IM 153) provides the S7-300 backplane bus within the ET 200M distributed I/O system. This active bus module enables removal and insertion of its two I/O slots while the controller is in RUN mode, allowing on-line changes without powering down the system. Identified by order number 6ES7195-7HB00-0XA0, it is used to extend ET 200M installations by adding two 40 mm-wide I/O modules and maintains backplane connectivity across the S7-300 bus. Typical applications include distributed automation on manufacturing lines, packaging, and process-control cells where quick module swaps with minimal downtime are advantageous.
