Overview:
XR830 series is a kind of programmable measurement, display, digital communication and power transmission output of pulse functions such as multi-function network monitoring and control instrumentation, power distribution system for continuous monitoring and control, and have an analog quantity output function to send a maximum Demand statistics, the relay alarm outputs can be used for the more limited, or remote control, alarm threshold can be set free, the switch input DI can be used to monitor the switch status, to complete the power measurement, energy measurement, data acquisition, display and transmission, It can be widely used in substation automation, distribution automation, intelligent building, internal energy measurement, management, and evaluation. Active energy measurement accuracy of 0.5s level, to achieve LED display and remote-site digital interface RS485 communication using MODBUS-RTU communication protocol.
