Siemens 6GK5101-1BB00-2AA3 Media Converter

The 6GK5101-1BB00-2AA3 converts between electrical and optical network signals. This media converter connects copper Ethernet segments to fiber optic cables. Its rectangular frame measures 45 millimeters in width. The converter height reaches 85 millimeters exactly. Depth stays at 105 millimeters. You will find this unit weighs approximately 0.22 kilograms. Therefore, installation requires clipping the unit onto a standard DIN rail. One RJ45 port handles copper connections while one ST port manages fiber.

Physical Layout and Connectors

The front panel features one shielded RJ45 Ethernet port for copper cabling. One ST-type fiber optic port provides the optical connection. Two status LEDs indicate link activity and power presence. A DIP switch allows manual configuration of port settings. Four mounting tabs secure the unit to TS35 DIN rails.

Internal Design and Energy Storage

The 6GK5101-1BB00-2AA3 contains exactly 86 discrete components inside. A 100 microfarad capacitor bank filters noise from the DC power input. A media conversion chip handles the electrical-to-optical signal translation. The unit includes an LED driver for the two status indicators. The fiber port uses an LED light source for multimode transmission. The RJ45 port includes built-in transformer isolation for safety.

Operational Performance

This media converter connects copper PROFINET networks to fiber optic backbones. It extends network distances up to 3 kilometers using multimode fiber. Moreover, the unit automatically detects speed and duplex settings. You can install this converter to isolate network segments electrically. The module passes all network protocols transparently without configuration. Two LEDs provide clear visual indication of link and power status. Consequently, you achieve long-distance network connectivity for industrial systems. Siemens designed this converter for PROFINET compatibility. Its rugged construction suits factory floor and equipment cabinet installations.

In summary, the 6GK5101-1BB00-2AA3 delivers reliable media conversion. Use this unit for extending Ethernet networks over long distances. It provides electrical isolation between connected devices. Order this media converter for your Siemens industrial network.
