LYD105A is an interface module designed for Dongtu SICOM3028GPT series switches that support clock synchronization function. Through this module, SICOM3028GPT switches can be equipped with master clock level timing capability. The module can acquire time via BeiDou/GPS/GLONASS satellite system, or PTP/IRIG-B, and also can be used to time other devices via PTP/NTP/IRIG-B in various ways.

LYD105A also has a very high timekeeping performance, can continue to provide high-precision clock information after the loss of satellite signals. The module supports TMS function and can report system time synchronization status through IEC61850 MMS, IEC60870-5-104, DNP and other ways; it can also trigger measurement and monitoring of clock synchronization through the release of GOOSE message, and realize system configuration and management through SNMP or WEB system.
