Siemens 6GK1102-5AA00

Siemens 6GK1102-5AA00 is a SIMATIC NET Electrical Link Module (ELM) that provides three ITP ports and one AUI port to connect industrial Ethernet networks and legacy Siemens devices. It includes a redundant power supply and a signaling contact, and is designed to operate from 18 to 32 V DC. The enclosure measures 80 x 140 x 85 mm and weighs approximately 850 g, making it suitable for panel or rail mounting in control cabinets. This model is part of the SIMATIC NET family and has reached end-of-life status, being discontinued; users typically migrate to newer SCALANCE X hardware for ongoing support and compatibility. Typical applications involve bridging between industrial Ethernet networks and legacy ELM-compatible links, providing a dedicated electrical interface to maintain reliable network connectivity in automation environments.
