Overview

MG-720DYB - Multi functional digital display instrument series power measurement and control instrument is a multifunctional combination instrument developed by Ningbo Dongqi. Suitable for on-site monitoring and display of power grids and automation control systems, as well as remote control and telemetry of remote control devices for automation scheduling. Its function is to directly control the electrical parameters in the power grid, such as current, voltage, power, frequency, power factor, and electrical energy, and output standard current, voltage, or switch signals through AC sampling A/D analog-to-digital conversion controlled by the CPU, which is connected to the remote data terminal RTU. The RS-232 or RS-485 interface of the instrument can be directly connected to the control center

MG-720DYB----Multi functional digital display instrumentThe series of power measurement and control instruments is a multifunctional combination instrument developed by Ningbo Dongqi. Suitable for on-site monitoring and display of power grids and automation control systems, as well as remote control and telemetry of remote control devices for automated scheduling. Its function is to convert electrical parameters such as current, voltage, power, frequency, power factor, and electrical energy in the power grid intoCPUControl direct communication samplingA/DOutput standard current, voltage, or switch signals after analog-to-digital conversion, and communicate with remote data terminalsRTUto be connected. instrumentalRS-232orRS-485In the interface, data exchange can be directly carried out with the control center to achieve automated management. In addition, this series of instruments also has intelligent functions for non electric measurement, transmission, and alarm input and output, such as pressure, temperature, and flow.

At present, this series of instruments has been widely used in industries such as water conservancy, environmental protection, power, metallurgy, and railways.
