Filter the results by "Manuals" and select the version matching your relay’s firmware (e.g., V7.x or V8.x/V9.x). Siemens 7ut82 Relay Manual Pdf
Modern substations require robust data communication. The 7UT82 includes an integrated electrical Ethernet RJ45 port supporting DIGSI 5 engineering software and the IEC 61850 protocol (including GOOSE messaging). It supports optional pluggable modules for redundant protocols like IEC 61850, IEC 60870-5-103, Modbus TCP, DNP3, and PROFINET IO. Cybersecurity features meet standards such as NERC CIP, including role-based access control, syslog, and secure authentication.
