Because every fraction of a second counts 

To all our customers, partners and friends!

The turn of the year draws closer and preparations for closing 2016 are in full swing. Nevertheless the next business year has to be prepared properly to enable a successful start from the beginning. Therefore we proudly present the two latest additions to our product range today – because every fraction of a second counts:

Network timeserver 8030NTS/GPS

highly precise network synchronization in a compact DIN rail housing

Completely maintenance-free and space-saving hopf network timeserver for DIN rail mounting with up to 2 isolated and mutually independent timeserver modules and up to 4 ethernet interfaces ensuring enhanced security for business critical and even most demanding applications!

Base system 8030NTS/GPS is equipped with 1 network timeserver module by default:
  • 2 ethernet interfaces 10/100/1000 Mbit/s autosensing
  • Network Time Protocol Version 4 (RFC5905)

To ensure enhanced security and availability in redundant networks one additional, isolated and independent network timeserver module 8030NTS/M may be integrated in the base system at time of purchase.

Optionally the network timeserver 8030NTS/GPS may also be equipped with various other signal output modules.

For detailed information please have a look at the 8030NTS/GPS-brochure.
