The device inherits the rich R&D and onsite operation experience of our company in relay protection devices, measuring and control devices, communication devices and distribution network automation. Many relevant aspects are taken into account and various technical methods are adopted. The terrible operating conditions for the device are fully taken into account in the design. The device features excellent electromagnetic compatibility, low power consumption and a wide range of operating temperature. It is shockproof, moisture-proof, lightning-proof and of great reliability and stability.
It boasts of all the functions required for the present relay protection and can carry out on/off combination according to the practical requirements. It can fulfill the “four-remote” (remote signaling, remote metering, remote control and remote regulating) functions through the local serial ports and realize the remote communication function by different optional communication modes.
iability and stability.The product is equipped with RS-232/485 (standard configuration: RS-232) communication interface to fulfill the wired remote control, wireless remote control, optical fiber remote control, carrier remote control and other kinds of remote control by the support of related equipment. Remote signaling, remote metering, remote control and remote regulating can be carried out through local communication ports.
Communication modes: GSM SMS, PDA wireless communication, GPRS wireless network, optical fiber communication, Ethernet, carrier communication through power broadband, etc.
Communication protocols: Various protocols are supported and can be adjusted as required. The basic configuration supports 101 balanced protocol, 101 unbalanced protocol, 104 protocol, DNP3.0 and Modbus communication protocol (standard configuration: 101 balanced protocol).
