Analog quantity The analog quantity of the input and output module is an arbitrary value that represents the continuous change in a certain range. It is the state representation opposite to the digital quantity. Analog quantities are usually used to collect and represent parameters such as voltage, current or frequency of things. Drive the hardware output and related data channels, select the current set value according to the operation mode, or reverse it as needed, and provide the result to the hardware output or software output. This is the analog input module. The analog input module is a kind of intelligent module, which can collect voltage, current, thermocouple, thermal resistance, temperature and other analog values, and transmit to the computer through the 485 bus. The main function of the analog output module is actually to convert the input digital signal into digital analog and output adjustable continuous voltage, current and signal.
Such as in the TV control block for a variety of analog control, if in sound, for example, first the digital pulse signal from the remote control or button scanning input to the control block, after analog output module of d/a conversion, output can follow the continuous change of the input signal voltage signal, and then using the signal control audio channel, so as to control the volume, brightness and contrast. In addition, analog output modules are not only used in these places, but are now widely used in various intelligences.
For example, the analog input module is good or bad, it can give the standard signal to see whether the collected value is correct, and the analog output module outputs a value. If the measurement range is consistent, the input and output can be measured. The analog module has input and output, and the switch module also has input and output. Such modules save space. Because if it’s not integrated like this, if you need input and output, you have to order at least two modules, and if it’s arranged like this, you only need one module. Integrated input/output modules mean that there are both input and output signals on the same module.
The functions of analog input/output modules used in other fields also include various acquisition functions, control functions, display functions, remote management functions, alarm functions and storage functions. Acquisition function is to collect pressure, temperature, displacement and other transmitter standard signals. Collect flow data of flowmeter and pulse meter; Collect the running status of the pump or valve, the power supply status of the device, and the switch status of the door. Control function is to support automatic control, remote control pump, valve and other control equipment. Display function for digital tube display, optional LCD display, external display screen. Remote management supports remote parameter setting and program upgrade through GPRS transmission devices. If the monitoring data of the alarm function exceeds the limit, report the alarm information immediately. Storage function: The machine stores monitoring data in a cycle, and will not be lost after power failure.
