The CD194 series power transmitter is an instrument developed by Ningbo Qixunda that can convert the measured AC current, voltage, and power signals into DC current or voltage output in linear proportion. Equipped with corresponding indicating instruments or devices, current and voltage measurement and control can be achieved in the AC circuit of the power system. 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 directly exchange data 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.
