TC-OAH061 Honeywell Analog Output Module
Analog quantity The analog quantity of the input and output module is an arbitrary value that represents continuous changes within a certain range, and is the opposite of the state representation of the digital quantity. Analog quantities are often used to capture and represent parameters such as voltage, current, or frequency of things. Drive 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 an intelligent module that can collect analog values such as voltage, current, thermocouple, thermal resistance, and temperature, and transmit them 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 mode, and output adjustable continuous voltage, current and signal.
For example, the control of various analog quantities in the TV control block, if the sound is taken as an example, the first remote control or key scan pulse digital signal input into the control block, after the analog output module digital-to-analog conversion, the output can change with the input signal continuous voltage signal, and then use the signal to control the sound 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 kinds of intelligence.
For example, the analog input module is good or bad, can give a standard signal to see whether the collected value is correct, and the analog output module outputs a value. If the measurement range is consistent, it can be measured by input and output. The analog module has input and output, and the switching module also has input and output. Such modules can save space. Because if it is not integrated in this way, if you need input and output, you need to order at least two modules, if you arrange it in this way, only one module is needed. Integrated input/output modules mean that there are both input and output signals on the same module.
