The SID-2X-B Synchronous Line Selector is an smart line-selection device designed for multi-synchronization-point applications in power plants and substations. It supports manual or automatic switching among 2 to 8 synchronization channels, providing flexible and reliable synchronization point selection.

The device features scheduled self-diagnostics, automatic interlocking and re-selection, event recording, remote control, and local manual point selection, significantly enhancing the safety and automation level of synchronization operations.

Supporting the Modbus communication protocol and IRIG-B time synchronization, the SID-2X-B can be integrated into SCADA systems for centralized monitoring and management. With a user-friendly bilingual (Chinese/English) interface, it serves as an ideal auxiliary device for building intelligent grid-connection systems.
