Introduction SPT series Protocol Converter mainly be used to centralized management of various of protective relays device and other intelligent devices, as well as to convert the communication protocol. Through many kinds of standard communication interface to have data communication with relay protection, fault recorders, watt-hour meter, DC screen and so on devices, then send to background control system by net or serial port, or send to remote dispatching center by modem after program processing. It is suitable to extremely adverse condition, and can be widely used to distributed data acquisition and transmission of all levers electric power automation system. Features To adopt Motorala 32-bit high performance microcontrollers and commercial real-time multifunction operating system that makes sure of the product stability and operation speed. High quality industrial element, high lever electrical design and high density integrated circuit structure enable the device have excellent electro-magnetic shielding and electrical isolation. The integrated machine has no adjustable element that greatly enhances the ability of anti-interference and the reliability of the device. Having high speed and reliable communication interface such as Ethernet and serial port for system extension to strengthen the device scalability and allocation flexibility. Flexible on-line and off-line debugging, reliable program upgrading and parameter download and data query functions meet the need of ever new and faster network information age. Integration can be equipped with acquisition protocol CDT.103,MODBUS, and Transmission protocol CDT,101,104,DNP. Free send EasySPC maintenance allocation software. Customers can self regulated to finish protocol debug quickly according to the on-site, and also can make special protocol development according to the on-site demand. Be provided with great ability of self -diagnosis and self -healing, the system can be self-recovered in a short time when causing program operation error by outside interference or other reasons. ; Use real time operation system Nucleus as the platform, realize multifunction, on the basis of communication program of message queuing, face all objects: object programmer, communication port and
