Overview
DTU 2000 series (Distribution Terminal Unit) is a distributive data acquisition and control system based on
microprocessor. In common SCADA (Supervisory Control and Data Acquisition) system, DTU performs the tasks of
collecting and processing of station data for both analog and digital signals; then DTU-2000 receives the command
from host in master station and transmit back the acquired data, also to perform the function "check before
execution" for station facilities to ensure a safe and reliable execution in system control.
The design of DTU 2000 series is fully modularized with different I/O cards which combines with the communication
ability. The idea for design of DTU 2000 is to be an aesthetic product with quanlity of long-term stability, easy
maintenance, convenient wiring and flexibility in expansion. In the requirements of today's power utility such as
engineering, operations, and maintenance departments; DTU 2000 series offers flexible and economical solution.
The combination of different types of I/O cards made DTU 2000 to fulfill the different applications from small
distribution to large substation or any generation stations. DTU 2000 series comes in an open architecture through
internal fully protected high-speed I/O LAN (Local Area Network) easy for new additional new processing modules.
When DTU 2000 expands from small system to large or complex system, the existing cards and modules do not
become obsolete. The DTU 2000 series can serve as communication server or the IED as below :
IED
To use DTU as the IED equipment, there are two independent communication channels are provided by DTU CPU
Card. One links to the host computer and the other one links to the power meter or IEDs for obtaining I/O information
for such equipment and also transferring the output control command. Furthermore, the DTU also provides with I/O
cards (AI, DI, AO, DOH and more) to collect the field information and to carry out the output of control command.
