Click 首先你看到的是不带控制功能的过流保护继电器. Click 接下来看到的是我们的保护及控制继电器. Click 现在你所看见的是能显示一次接线图的保护与控制继电器. Click 最后你所看到的是带分离人机界面的保护与控制继电器. Click.. Independent: The software for the protocols are on the communication modules. These modules have their own processor. Norm: IEC 60870-5-103 Now I introduce an example for communication with our relay. Click The front port is for the operating program DIGSI. Click The rear port is for remote interrogation with the operating program DIGSI. Click The 2nd rear port is for remote control. Here I show the integration of some relays into a SS control system. Click The PROFIBUS is a high capacity interface to the SS control system. Click The local front interface is for local parameterisation with DIGSI. Click The rear interface is for central engineering, parameterisation and remote interrogation with DIGSI too. Click It is also possible to connect an engineering PC at the PROFIBUS. Now I want to talk about the communication possibilities of our protection control relays. In the front plate of our relays is a RS232 port for the operation program DIGSI. Click On the rear is a RS485 or fibre optic port for the operation program DIGSI available. Click On the rear is a time synchronism port for a GPS receiver too. Click A 2nd port for SS control is available. Click For the distance protection relay 7SA522 are 2 additional ports av
