Sunyuan Technology SY Series Intelligent Digital Display
 
 

Sunyuan Technology the newest developed SY LED / SY LCD series,with low cost, small size isolation transmitter 4-20mA two-wire passive intelligent display control instrument, dedicated to sensors and isolation transmitters |isolation amplifiers | PLC | DCS, etc.Isolated transmission of analog signals and intelligent display control. These LED or LCD four-bit high precision intelligent digital display meters use the principle of two-wire passive digital adjustment. The electrical signal passed through the digital measuring circuit is used as the input signal of the display meter and also the working power of the display meter. This two-wire passive type of operation eliminates the need for additional auxiliary power supplies. It is easy to connect in industrial field and has reverse protection and overcurrent protection. Products are widely used in industrial intelligent control, instrumentation intelligence, petrochemical, environmental monitoring, rail transit, electric vehicles, smart home, fire safety, mining monitoring and other industries on temperature, pressure, flow, liquid level, displacement, speed, frequency Monitoring of physical quantity control points. In industrial control systems, most applications use a variety of related sensors to convert physical quantities such as temperature, pressure, and displacement into 4-20 mA electrical signals, and intelligent digital display displays these electrical signals in real time for human convenience. Carry out all kinds of monitoring and control
