Analog quantity acquisition is analog signal input, which refers to input as a continuously changing physical quantity. Unlike digital quantities that are simply 0 and 1, current and voltage are two different ways to activate the analog input unit. The more bits there are, the finer the analog quantization, and the more accurate the result.
The application fields of analog quantity collectors are very wide, such as building automation, industrial automation, environmental monitoring, intelligent transportation, etc. If the analog quantity collector is used in the sewage treatment online monitoring system, then the analog quantity collector is a monitoring device used to collect pollution sources. The collected pollution data and alarm information can be remotely sent to the environmental protection monitoring department through the wireless network. , to achieve timely management of pollutant discharge units or individuals, which can greatly improve the work efficiency of the environmental protection department.
The analog collector not only supports data collection function, but also can realize remote control function. The collection function is to collect standard signals of pressure, temperature, displacement and other transmitters; collect flow data of flow meters and pulse meters; collect the operating status of water pumps or valves, equipment power supply status and door opening and closing status. The control function supports automatic control and remote control of water pumps, valves and other control equipment.
Zongheng Intelligent Control’s intelligent collecteur analogique has 8 channels of 4~20mA analog inputs and adopts a single-ended input design. The RS485 interface has photoelectric isolation and power isolation technology, which can effectively suppress interference. In addition, it also supports 16 IO interfaces to meet various application needs. Lightning protection circuits are added to the power supply and all interfaces to ensure that the product is stable and reliable when in use. Rich indicator lights can facilitate debugging and the operating status is clear. In addition, the standard Modbus RTU protocol is adopted, which is convenient for system integrators and engineering contractors. Data collection and control of remote analog devices can be achieved through RS485.
