Product Overview
This series of instruments is a multifunctional intelligent instrument with programmable measurement, display, digital communication, and power pulse output. It can complete power measurement, energy metering, data display, collection, and transmission, and is widely applicable in substation automation, power distribution automation intelligent buildings, and internal enterprise power energy measurement, management, and assessment. The multifunctional network instrument enables LED on-site display and remote RS-485 digital interface communication. Two power pulse outputs and four analog (DC0-20mA) output channels enable transmission and output of electric energy and power outputs; Four switching input and four output channels enable local or remote switching signal detection and control output ('remote signal' and 'remote control' functions), and can be combined to realize multiple power parameter alarms and automatic control functions. Uses MODBUS-RTU communication protocol.
