The 6890 product series 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 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 6890 product series time synchronization systems feature on receiver and firmware level consistency checks and statistical tests such as automatic gain control (AGC), clock error, signal quality, signal power, propagation delay and the angle of arrival in order to safeguard error free and leap free time signal evaluation.
In case of signal loss due to antenna failure or identification of time signal mismatch (e.g. due to jamming or spoofing attacks) the time synchronization module clock automatically switches to the integrated oscillator holdover ensuring the oscillator dependent freewheeling accuracy.
 
The 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.
 
The current demand for the convergence Information Technologies (IT) and Operational Technologies (OT) in critical infrastructure requires to ensure security and reliability in compliance with regulatory requirements.
The system design of the 6890 product series allows separation of operational and productivity network for enhanced security with the built-in firewall feature that adds increased security against network-based intrusions by limiting access to the minimum necessary network connections and services.
Role based access control according to the most up-to-date standards safeguards secure access to the system by authorized staff.
