TYHD-DTU distribution automation remote terminal with High-reliability software platform and Self-test
DTU power distribution network feeder automation device is with a hardware platform of 32 bits of microprocessor of high-performance, is with embedded real-time operation as a software development platform, also with characters of high stability and reliability , high performance,high intensity and low cost and easily installation.
DTU provides enough communication interface( 4 technical grade RS232 Serial ports, 2 of them can be equipped as RS485 ports,2 pieces of 10M Ethernet port,1 piece of USB port),main processor adapts technical grade 32 bits of high-performance processing chip, with specialized maintenance software, also can be remotely kept maintenance by specialized network, such as each CPU module is realized by bus. Main CPU module is as master station to control the whole communication process, the gathering CPU Module is as subsequent station, the communication rates is above 9600bps. Several device constitutes Ethernet bus through inner embedded industrial grade switch to make sure data processing and data exchange with sufficient bandwidth. ·
Distribution terminal assembly
The power distribution terminal is divided into a core measurement and control unit area, an operation panel area and a wiring terminal area according to functions, and an internal operation panel area is built in the battery. If you need to install communication equipment such as fuse box and carrier, the power distribution terminal can be equipped with a communication box. The functional area is divided as shown in the table below..
The key technical indexes:
| Remote signal performance | Remote circuit voltage | DC24V |
| Remote signal resolution | £2ms | |
| Remote signal anti-shake time | 0~60S, Level difference 1ms | |
