FAQ
Q:How to select RTU Communication Panel?
A:How to choose a communication panel? Here are my personal opinions. It is advisable to select products from the same manufacturer for the communication panel, relay protection panels and the entire relay protection system of the power station, facilitating subsequent commissioning. Strictly follow technical documents, as specifications and configurations of communication panels vary by technical requirements. Blind selection may cause operational troubles in later use.
Q:What communication interfaces does the RTU communication panel support?
A: It is equipped with RS485, Ethernet and optical port, compatible with IEC60870-5-101, IEC60870-5-104 protocols to realize data interaction between field devices and master station.
