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.

- Data be temporarily saved in

the memory

- Memory space can last for 15

days.

- Upload be continued

automatically when network

recovered
