SXD300-D20 Two Remote Standard Station Terminal

Telemetry function: can detect AC analog quantities such as voltage and current, as well as DC analog quantities such as battery voltage and temperature;
Remote signaling function: It can detect switch status signals, switch energy storage signals, battery low voltage alarms and other status information, and has dual position remote signaling processing function, supporting remote signaling displacement priority transmission;
Therefore, it refers to the data collection function: receiving fault indicator fault current, ground fault, short circuit fault and other data;
Monitoring function: It can receive remote signaling signals such as fault indicator grounding fault, short circuit fault, and indicator abnormality, and forward them to the main station;
Fault detection function: It can detect single-phase grounding, phase to phase short circuit, overcurrent and other faults, and can identify the direction of fault current.
Communication function: equipped with serial port and network communication interface, can be achieved through fiber optic/Ethernet GPRS/CDMA、 Upload telemetry and remote signaling data to the main station through power line carrier and other methods.
Parameter configuration function: It can remotely download and read terminal parameters.
Time synchronization function: It has time synchronization function, supports SNTP and other time synchronization methods, receives time synchronization commands from the main station or other time synchronization devices, and maintains synchronization with the system clock;
Maintenance function: It can perform local debugging and maintenance using specialized maintenance software through standard communication maintenance interfaces, and support the main station to remotely and automatically upgrade the software, parameters, and communication protocols of the terminal using communication channels.
Self diagnosis and self recovery function: With self diagnosis function, when internal software and hardware abnormalities are found, they can be immediately recorded and reported, and the software has power on self recovery function.
Power management function: Supports backup power supply from dual AC power sources, using batteries or supercapacitors as backup power sources, and seamlessly switching to soft switching technology. When the main power supply fails, the backup power supply can automatically and seamlessly switch to operation; Capable of providing supporting power supply for communication equipment and switch opening and closing simultaneously; Equipped with battery activation management function, it can automatically and manually charge and discharge the battery.
Reset function: It has manual reset, automatic reset, and remote reset functions for the main station.
