Analog quantity is a common signal point in the industrial control industry. Its function is to convert the value of physical quantity into an electrical signal. Analog output is basically used to control execution equipment, such as controlling the opening of valves, controlling the speed of frequency converters, etc.
In industrial production, especially chemical production, many regulating valves are often used. We need to control the opening of the valve according to the speed of the pipeline fluid or other parameters, and this requires the use of analog output for control.
To this end, Zongheng Intelligent Control has developed an analog 4G data transmission terminal – ZHC4661, which provides 4-channel AI, 2-channel AO and 1-channel RS485 interfaces, supports 4~20mA analog control acquisition, and is suitable for automation, Information system.
This product is aimed at industrial applications. Its RS485 communication interface adopts a photoelectric isolation design to avoid the impact of industrial field signals on the communication interface. It has good compatibility and stability and supports online communication with multiple devices on the same bus.
This product supports the standard Modbus UTR /TCP communication protocol and common function codes. During use, customers can easily integrate it with configuration (SCADA) software and PLC equipment and systems that support the Modbus RTU/TCP protocol. The operation is very simple and flexible. , efficient.
