The Siemens SIMATIC ET 200SP BA LC/RJ45, article number 6ES7193-6AG20-0AA0, is a PROFINET Bus Adapter from the SIMATIC ET 200SP Bus Adapters family. It is designed as a media converter between a glass-fiber LC connection and a standard RJ45 copper Ethernet connection. The unit provides one PROFINET interface implemented as a two-port switch, with one LC port and one RJ45 port. The LC interface uses multimode glass fiber with a wavelength of 1,270–1,380 nm, corresponding to 100BASE-FX. Supported cable lengths are up to 100 m for copper and up to 3 km for both specified multimode fiber types. The Bus Adapter is intended for compatible ET 200SP PROFINET devices and can be used where optical and copper network segments need to be integrated within an industrial automation network. Siemens specifies -30 to +60 °C for horizontal installation and -30 to +50 °C for vertical installation.

3. Key Features

• BA LC/RJ45 configuration for SIMATIC ET 200SP.
• One PROFINET interface with an integrated two-port switch.
• One LC optical port and one RJ45 electrical port.
• Supports multimode 50/125 µm fiber up to 3 km.
• Supports multimode 62.5/125 µm fiber up to 3 km.
• Supports copper cable lengths up to 100 m.
• LC interface operates at 1,270–1,380 nm and corresponds to 100BASE-FX.
• Provides media conversion between optical glass fiber and copper Ethernet.
• Designed for compatible ET 200SP PROFINET devices.
• Operating temperature depends on mounting orientation.  

4. Typical Application

• ET 200SP distributed I/O installations using PROFINET.
• Industrial Ethernet networks requiring optical-to-copper media conversion.
• Factory automation control cabinets.
• Distributed automation stations connected through multimode fiber.
• PROFINET network sections where an LC fiber connection must interface with RJ45 copper.
• Industrial network architectures requiring the integrated two-port Bus Adapter switch.  

5. Product Highlights

The 6ES7193-6AG20-0AA0 combines an LC multimode optical interface and RJ45 copper interface in a compact ET 200SP Bus Adapter. Its integrated two-port switching arrangement allows PROFINET network connectivity through either side of the adapter. The 3 km multimode-fiber capability provides considerably longer optical reach than the 100 m copper segment supported by the RJ45 side, making the adapter suitable for distributed industrial network layouts.  

6. Important Ordering & Installation Information

• Order using the exact Siemens article number 6ES7193-6AG20-0AA0.
• The adapter is the ET 200SP BA LC/RJ45 version and should not be confused with BA LC/FC or BA LC-LD/RJ45 variants.
• The compatible ET 200SP device must support the Bus Adapter arrangement.
• Installation requires the Bus Adapter to be mechanically attached to the compatible PROFINET device.
• Select compatible multimode fiber and RJ45 copper cabling according to the specified interface limits.
• Observe the different temperature limits for horizontal and vertical installation.
• Siemens specifies restrictions for installation altitudes above 2,000 m.
• Hardware functional status is specified from FS04.  

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

7. Why Choose Siemens 6ES7193-6AG20-0AA0?

The Siemens 6ES7193-6AG20-0AA0 is suitable when an ET 200SP PROFINET installation requires conversion between multimode glass fiber and conventional RJ45 Ethernet. Its LC/RJ45 combination, integrated two-port switch, 3 km optical reach and compact ET 200SP form factor support flexible industrial network integration. Its documented temperature and altitude characteristics also provide clear engineering criteria for cabinet installation.
