Descripción

El TTM 01-G es un reloj GPS y GLONASS (GNSS) confiable y preciso con temporización de sub-microsegundos que se utiliza para sincronizar IED (dispositivos electrónicos inteligentes) en la industria de la energía y otras industrias donde se requiere una sincronización precisa y confiable. Al igual que con todos los relojes GPS de Tekron, el TTM 01-G tiene salidas aisladas eléctricamente, lo que proporciona una excelente inmunidad al ruido.
