Siemens 6GK5101-1BC00-2AA3 Electrical Switch Module

Siemens 6GK5101-1BC00-2AA3 is an unmanaged SCALANCE X101-1LD Ethernet media converter that bridges a copper 10/100 Mbps RJ45 interface to a 100 Mbps fiber optic link, featuring a fiber port with ST or BFOC connectors for industrial network installations. The unit provides one copper Ethernet port and one fiber optic port, includes LED diagnostics to monitor link and activity, and includes an error signaling contact with a set pushbutton for local fault signaling. It is designed with primary and redundant power inputs to support high-availability operation and uses PROFINET-compliant securing collars for stable mounting in panels. Typical applications include extending or isolating industrial networks by bridging copper Ethernet to a fiber link within the SIMATIC NET SCALANCE X lineup. This part is cataloged by Siemens as 6GK5101-1BC00-2AA3 and is listed as a spare part.
