The Siemens 6ES7193-6AG50-0AA0 is a SIMATIC ET 200SP BA 2xLC-LD PROFINET Bus Adapter designed for long-distance single-mode fiber communication. It belongs to the ET 200SP Bus Adapters family and provides one PROFINET interface implemented as a two-port switch using two LC-LD single-mode fiber-optic ports. Siemens specifies 9/125 µm single-mode fiber with a maximum cable length of 20 km, reduced to 10 km for topology or IRT configurations. The optical interface operates at 1,270–1,380 nm and corresponds to 100BASE-LX. The adapter is designed for compatible ET 200SP PROFINET devices and is suitable for industrial networks where long-distance optical connectivity is required. Current Siemens documentation specifies -30 to +60 °C for horizontal installation and -30 to +50 °C for vertical installation, with a maximum installation altitude of 5,000 m subject to restrictions above 2,000 m.

5. Product Highlights

The principal advantage of the 6ES7193-6AG50-0AA0 is its long-distance single-mode optical interface. Two LC-LD ports allow PROFINET networking over 9/125 µm fiber with a documented maximum length of 20 km. Siemens also specifies a 10 km limit for topology or IRT configurations, making the exact network architecture important during engineering.  

6. Important Ordering & Installation Information

• Order using the exact Siemens article number 6ES7193-6AG50-0AA0.
• This is the single-mode BA 2xLC-LD version and is distinct from the multimode BA 2xLC.
• Use compatible 9/125 µm single-mode optical fiber.
• Observe the 20 km general fiber-length limit and the 10 km limitation applicable to topology or IRT configuration.
• Verify optical attenuation and network design against the documented optical parameters.
• Confirm that the host ET 200SP PROFINET device supports the Bus Adapter.
• Observe mounting-orientation temperature limits and altitude restrictions.  

Always follow the manufacturer's official installation, wiring, commissioning and safety instructions.

7. Why Choose Siemens 6ES7193-6AG50-0AA0?

The Siemens 6ES7193-6AG50-0AA0 is designed specifically for ET 200SP PROFINET applications requiring long-distance single-mode fiber. Its two LC-LD ports, 20 km optical capability and integrated switching make it suitable for extended industrial network layouts where conventional copper connectivity is insufficient. The documented optical parameters also provide useful engineering limits for network design.
