Data Acquisition Unit
Description
The Data Acquisition Unit (DAU) is part of the S8000 Plus System. It
samples the signal inputs such as rotating speed, vibration, process
variables, converts them from analog to digital and transfers the data to
WEB8000 Plus.
It supports the TCP/IP protocol based on the Ethernet (10M/100M)
standard, and transmits data via the enterprise network. In addition it is
characterized by high speed, high accuracy, high reliability, easy

installation and connection, maintenance-free.
Meanwhile, the DAU is the first field acquisition station in the world with
a WEB function. From a computer on the same network with the DAU, a
user can view spectrum and other data from the DAU with IE browser.
According to the application and capacity, there are 6 types of DAU. They
are NET8000 Plus, NET8000 Dual, PWR8000 Plus, PWR8000 Dual and
HYD8000 Plus, HYD8000 Dual.
