The highly-flexible time server 8030HEPTA

Short Description

The network time server 8030HEPTA/GPS is ideal for everyone searching for a space-saving and budget-friendly solution with numerous configuration and extension options.

Assemble your 8030HEPTA/GPS based on your individual requirements:

  • One integrated time server module per default with:
    • 2 ethernet interfaces 10/100/1000 Mbit/s autosensing
    • Network Time Protocol version 4 (RFC5905)
  • Choose to equip free slots with additional output modules (available in various electrical signal output versions as well as modules for fiber optic output):
    • up to 4 additional isolated and mutually independent network time server modules 8030NTS/M
    • IRIG-B (modulated / unmodulated)
    • DCF77 (modulated / unmodulated)
    • Cyclic Pulses (PPS, PPM, etc.)
    • Serial time datagram
  • Activate optionally available functions per time server module:
    • Alarming
      • SNMPv2c / SNMPv3 (MIB II, hopf Private Enterprise MIB, SNMP traps)
      • E-Mail notification
      • SYSLOG
    • Routing for configuring static routes based on special network configuration requirements
    • VLAN support according to IEEE 802.1Q
    • Port aggregation (NIC Bonding/Teaming) with support of IEEE 802.3ad trunks
    • Parallel Redundancy Protocol (PRP) according to IEC 62439-3
    • Precision Time Protocol (PTP) according to IEEE 1588-2008
      • IEEE Standard Profile for Use of IEEE 1588 Precision Time Protocol in Power System Applications (Power Profile) according to IEEE Std C37.238-2011
    • SINEC H1 time datagram
  • Choose your required power supply:
    • 100 - 240V AC - (power supply in case of standard delivery)
    • 110 - 250V DC - (optionally available)
    • 24V DC (18 - 36V DC) - (optionally available)
    • 48V DC (36 - 76V DC) - (optionally available)


  • Space-saving 19" 1U/84HP rack chassis (Slim Line)
  • At-a-Glance status LEDs at front and rear panel
  • LCD display at front panel with background illumination for quick and easy commissioning and monitoring of operation status on site
  • Integrated 22-channel GPS receiver for L1 frequency (1,575.42 MHz)
  • One integrated time server module per default with:
    • 2 ethernet interfaces 10/100/1000 Mbit autosensing
    • Network Time Protocol version 4 (RFC5905)
  • Easy setup and configuration of the network time server modules via web interface, no serial connection necessary
  • Synchronization of IEC 61850 compatible devices
  • Four free slots available by default for cost-efficient extension of the base system with additional output modules ex works (modular order concept)
  • Integrated synchronization status output via optical coupler
  • Redundant multiple validation of synchronization signal for error-free and leap-free signal evaluation
  • SyncOFF timer ensuring accurate operation even in most difficult GPS reception conditions (reception failure bypassing)
  • High freewheel accuracy provided by GPS-aided regulation of internal quartz base, various crystals available
  • Buffered backup clock (restricted) for at least 3 days bridging time, maintenance-free
  • Automatic switch-over of daylight-saving time supported (configurable parameters for changeover switching points)
  • Automatic evaluation and handling of leap second
