Features
Design
Perfect self-checking function of hardware and software and design of adjustable-free circuit make debugging easier.
Hardware Design of Device
Integrative metal shell design, various isolation and shielding measures, complete separation of strong and weak electricity, superior EMC performance, digital filtering technology and advanced protection algorithm and other anti-interference measures are adopted in software design, which greatly improves the anti-interference performance of protection.
Flexible and powerful communication function
It supports not only RS485 serial communication mode but also Ethernet communication mode. The communication protocol supports DL/T667-1999 (IEC-60870-5-103) and Modbus protocol. It can flexibly communicate with other manufacturers'automation systems, support redundancy of main and standby dual networks, flexibly support network timing and GPS pulse timing, and ensure that the device is unified and accurate. Clock
Friendly man-machine interface
Large screen Chinese/English menu mode, clear structure, easy to use, flexible operation circuit configuration, can adapt to a variety of operating mechanisms
High-end configuration
32-bit high-performance embedded microcontroller, 16-bit high-precision AD synchronous sampling, infinite reading and writing of large-capacity data storage chip
Event Recording
Perfect event protection processing can store up-to-date 100 event report records, 100 action report records and 20 fault recordings. Each record can record 10 cycles of current and voltage waveforms. Events and fault recordings can be saved for a long time.
Perfect measurement function
It can complete the measurement and upload of the interval power point where the device is located, and the measurement accuracy can reach (+0.5)%. It has perfect remote communication and remote control functions. The backstage remote control circuit breaker tripping/closing is simple and reliable, and the SOE resolution in the station can reach 1 ms.
