- Miscellaneous VME / VXI Cards
- Wide Range of Equipment
This page is a list of miscellaneous Applied Materials VME / VXI cards spanning all categories.
An analog quantity is an arbitrary value that represents continuous change within a certain range and is the opposite
of a state representation of a digital quantity. The analog input/output module can convert analog quantities into
digital quantities and at the same time convert digital quantities into analog quantities.
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.
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 intelligences.
Simulate the function of the input/output 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.
The acquisition function is the standard signal of the transmitter such as pressure, temperature and displacement.
Collect flow data of flowmeter and pulse meter; Collect the running status of the water pump or valve, the power supply
status of the device, and the opening and closing status of the door.
The control function is to support automatic control, remote control of pumps, valves and other control
equipment. Display function for digital tube display, optional LCD display, external display.
Remote management function supports remote parameter setting and program upgrade through GPRS
transmission device. If the monitoring data of the alarm function exceeds the limit value, report the alarm information immediately.
