PXIE-5172 | 16-bit analog output module

The PXIE-5172 is a 16-bit analog output module from National Instruments (NI).

The PXIE-5172 has 2 analog output channels, 6 digital input channels, 2 digital output channels, and 16 configurable analog input channels. It has library isolation, source synchronization, 32-bit counter and other functions. The PXIE-5172 offers the best combination of isolated safety and performance benefits with precisely controlled high-performance timing, calibration technology and amplification to deliver accurate measurements. The module is considered an ideal solution for control, design, test and measurement applications in electrical noise and high voltage environments. In addition, through this module, users can read short-range sensors, encoders, flow meters, relays, control valves, and even pumps.

An analog output module is an electronic device that can convert a digital signal into an analog signal output. It is commonly used in systems that need to control analog devices, such as controlling motor speed, regulating temperature, controlling light brightness, and so on.

Analog output modules usually have multiple analog output channels, which can output different analog signals, such as voltage, current, frequency, etc. It can also set parameters such as the range, accuracy and resolution of the output signal to meet different application needs.

The PXIE-5172 analog output module is usually used in conjunction with digital control devices such as microcontrollers and PLC to control the output signal of the analog output module through the output signal of the digital control device. In practical applications, analog output modules usually need to be used in conjunction with external devices such as sensors and actuators to realize the control and monitoring of physical quantities.

The working principle of the PXIE-5172 analog data acquisition module is to convert continuously changing analog signals into discrete digital signals by using an analog-to-digital converter (ADC).

The analog-to-digital converter samples the analog signal at a certain sampling frequency and converts the sampled value to digital form. There are two common analog-to-digital converters: successive approximation type and Delta-sigma type. Successive approximation analog-to-digital converters compare the analog signal with the reference voltage in a step-by-step approach until the desired accuracy is achieved. The Delta-Sigma analog-to-digital converter obtains high precision digital signal output through high speed sampling and oversampling of analog signal, and then filtering and digital processing.
