Product Overview

The Siemens 6ES7195-7HA00-0XA0 is a specialized active bus module engineered for the SIMATIC ET 200M distributed I/O system. This critical hardware component serves as the mechanical and electrical foundation for the head-end station, specifically designed to accommodate one Power Supply (PS) and one Interface Module (IM 153-1 or IM 153-2). By facilitating a reliable backplane connection, this bus module ensures seamless data exchange between the field-level I/O and the central PLC. Its robust design is tailored for high-availability architectures, providing the structural integrity required to maintain a stable PROFIBUS DP or PROFINET network node in demanding industrial environments.

Technical Infrastructure and Physical Properties

The following specifications detail the mechanical and operational characteristics of the 6ES7195-7HA00-0XA0 unit:

• Module Capacity Supports 1 Power Supply (PS) and 1 Interface Module (IM 153)

• Active Bus Feature Enables "Hot Swapping" (Pulling/Plugging) of modules during CPU RUN mode

• Backplane Interface Integrated high-speed bus connectors for signal continuity

• Mechanical Protection Includes integrated bus module cover for shielding against debris

• Mounting Requirement Designed for installation on the specialized S7-300 active bus rail

• Operational Mass 0.95 kg

• Physical Dimensions 2.5 cm x 5.1 cm x 83.8 cm

• Country of Origin Germany

• Customs Tariff (HS Code) 8537101190

This bus module is essential for configurations where high system uptime is a priority, as it allows for the replacement of head-end components without disrupting the communication of the entire station.

Industrial Applications and System Resilience

The 6ES7195-7HA00-0XA0 is primarily deployed in process industries and large-scale manufacturing plants where production stops are prohibitively expensive. In chemical processing and water treatment facilities, this bus module allows maintenance teams to swap out a faulty power supply or interface module while the plant remains in operation, ensuring continuous monitoring and control. It is also a staple in automotive assembly and power generation sectors where decentralized ET 200M stations are linked via PROFIBUS. The integrated protective cover ensures that even in environments with high vibration or airborne contaminants, the internal bus pins remain secure and corrosion-free. By providing a ruggedized mounting platform for the SIMATIC S7-300 logic family, this module directly contributes to the resilience of distributed control systems (DCS), making it a fundamental part of any high-reliability automation strategy.
