Relay output, transmission output, power pulse, switch input (not included by default)
Describe
Multifunctional power meter is a kind of programmable measurement, display, digital communication
Multifunctional power meters with functions such as communication and power pulse transmission and output can complete power measurement, power measurement, data display, collection and transmission, and can be widely used in substation automation, power distribution automation intelligent buildings, and internal power measurement, management, and management of enterprises. Assessment. The measurement accuracy is 0.5, realizing LED field display and remote RS-485 digital communication interface, using MODBUS-RTU communication protocol
