GNSS Network Time Server 6890

Short Description

The FG6890Gxx are fully featured network time server systems for NTP (Network Time Protocol) supporting the Global Navigation Satellite Systems (GNSS) GPS, Galileo, GLONASS, and BeiDou for precise and reliable time synchronization at highly competitive pricing.

The 6890 product series network time server systems feature a compact design with small form factor housing for DIN rail mounting. With its integrated 72-channel GNSS receiver for GPS, Galileo, GLONASS, and BeiDou reliable satellite time signal evaluation is ensured even under challenging installation conditions of the GNSS antenna system.

The network time server systems FG6890Gxx are ideal for everyone searching for a space-saving and budget-friendly solution for network time synchronization using Network Time Protocol (NTP).

Redundant network connections easily can be implemented using the integrated port aggregation / bonding / NIC teaming feature or with optional activation of the Parallel Redundancy Protocol (PRP) / High-availability Seamless Redundancy (HSR) feature according to IEC 62439-3:2016 specification.

The systems are available with power supply via Power over Ethernet (PoE) and features a redundant power input for connection of 24VDC power source for enhanced availability.

The FG6890Gxx network time server systems are equipped with integrated management controller software which allows easy configuration and monitoring using the hopf unified management application huma® web edition which features secure access to the system via an intuitive to use state-of-the-art web interface.

The system continuously monitors the health status and the integrated time synchronization module. It collects diagnostic and statistical data for the integrated event log and for real time notification of critical events to external IT management systems using email messaging, SNMP traps or external SYSLOG server.
