Overview
The 6ES7195-1GG30-0XA0 is a Siemens SIMATIC DP mounting rail, 620 mm long, designed for the ET 200M distributed I/O system. It holds bus modules that support the removal and insertion function, allowing modules to be swapped under power without disrupting the backplane bus. The rail is constructed from aluminum with a galvanically isolated surface, weighing 1522 g, and is supplied as a single piece in a box.
This mounting rail serves as the mechanical backbone for ET 200M bus modules. The 620 mm length accommodates a full complement of modules typical for a medium-sized remote station. The galvanically isolated surface prevents ground loops between the rail and the modules, a critical detail when the station is part of a larger PROFIBUS or PROFINET segment. The removal and insertion function (hot-swap) is supported by the rail's mechanical profile, which aligns the bus modules' connectors and provides the necessary clearance for module exchange without powering down the station. This is standard for ET 200M systems where uptime is a priority.
Applications
The 6ES7195-1GG30-0XA0 is used within Siemens SIMATIC DP distributed I/O architectures, specifically in ET 200M remote stations. These stations are common in process automation, manufacturing lines, and material handling systems where I/O modules are distributed across a plant floor and connected via a fieldbus.
