Siemens 6ES7195-1GF30-0XA0 SIMATIC DP Mounting Rail

The Siemens 6ES7195-1GF30-0XA0, also cataloged as the 6ES7195-1GF30-0XA0 Mounting Rail, operates as a dedicated hardware component for mechanical module hosting and bus configuration within SIMATIC S7-300 and ET 200M distributed I/O systems. This 530 mm structural rail is precision-machined with internal slot clearances specifically engineered to anchor active bus modules, enabling the physical alignment required for the hot-swap removal and insertion function of peripheral cards under live backplane conditions.

Hardware Specifications

Siemens Distributed I/O Framework

• I/O Density Scaling Grid Mechanical Alignment: The 530 mm physical rail geometry acts as the structural foundation for high-density slot scaling. It defines the exact spatial layout and depth necessary for active backplane bus modules to interlock side-by-side, maintaining parallel contact pitch across maximum card configurations.
• Support for Active Bus Backplane Communication: This specialized rail supports the insertion and extraction of active bus modules. By securely locking these underlying bus connectors into a fixed mechanical plane, the rail ensures that individual electronic modules can be unseated from the backplane bus communication link without displacing or breaking the data continuity of adjacent active channels.

Frequently Asked Questions

Q: Can standard DIN rails be substituted for the 6ES7195-1GF30-0XA0 rail when using active bus modules?

A: No. Standard 35 mm symmetric DIN rails lack the specific depth profile and lower recessed channel necessary to accommodate the active bus modules. Attempting to mount active bus modules on a standard DIN rail prevents them from seating correctly, making it impossible to establish the underlying backplane logic bus.

Q: How does this mechanical rail support the electrical hot-swapping functionality of the ET 200M modules?

A: The rail provides rigid mechanical constraint and alignment guides. When an electronic module is pulled, the rail holds the underlying active bus module completely stationary, allowing the module's gold pins to separate cleanly from the active bus without causing mechanical torsion or short circuits across neighboring backplane data traces.

Field Installation Guidelines

• Chassis Layout Alignment, Clearance Constraints, and Mechanical Seating: Bolt the 530 mm aluminum rail horizontally onto a flat enclosure backplate using a minimum of three structural M6 fasteners through the integrated mounting holes. Maintain a 50 mm clearance perimeter above and below the rail to allow unrestricted ventilation airflow and sufficient finger room to actuate module shield clamps.
• Conductor Separation, Wireway Constraints, and Shield Grounding: Ensure that the bare metal mounting surface of the rail establishes direct, low-impedance contact with the grounded steel enclosure backplate. Connect a dedicated copper grounding strap from the rail’s integrated PE terminal stud directly to the main cabinet earth ground bar to safely discharge ambient electrostatic noise away from the active bus modules.
