Advantech offers a wide range of evaluation boards, expansion boards, and daughter cards. These components are used to evaluate and expand various industrial automation systems, and this article looks at the application fields and working principles of one such example: the Advantech EVAL-AD7946-PMDZ.

What is the EVAL-AD7946-PMDZ?

The EVAL-AD7946-PMDZ is an expansion board that is designed for Advantech industrial automation motherboards and industrial computers. It offers an adjustable potentiometer for input voltage range adjustment, and can also provide a right-angle type of terminal block for easy connection and operation. Additionally, it features protection functions for analog output, low-voltage detection, and over-temperature.

Application Fields

The application fields of the EVAL-AD7946-PMDZ are vast. It is commonly used with high-end machine vision systems, manufacturing automation systems, aerospace systems, defense systems, and medical systems. It is ideal for applications that require precise measurement and communication capabilities.

As the EVAL-AD7946-PMDZ can handle extreme temperatures, it is well-suited for rugged, outdoor applications. It is also convenient for installations in tight or hazardous working environments, and can be configured to provide protection against vibration and shock. This makes it an ideal choice for any application that requires stringent performance- and reliability- testing.

Working Principle

The EVAL-AD7946-PMDZ consists of a potentiometer, an analog output IC, and a Power Management IC. These components work together to provide an adjustable voltage range for the input, and a wide range of outputs. In addition, the board is designed to provide protection from abnormal events.

The potentiometer is responsible for adjusting the various components of the board. It can be adjusted to provide a high precision voltage reference, or to limit the upper and lower extremes of the voltage range. The analog output IC provides precision, stable voltage readings, while the power management IC reduces power consumption, ensuring that the system runs efficiently.

The board is also capable of protecting against abnormal conditions. For example, it can detect low voltage, and shut off the output until the voltage is within an acceptable level. Additionally, it can activate a warning signal, or cut off the output when the temperature exceeds a certain level.

Conclusion

The Advantech EVAL-AD7946-PMDZ is a versatile and powerful expansion board for industrial automation systems. Its adjustable potentiometer allows for precise voltage ranges, and its power management features ensure efficient operation. Moreover, its protection features provide reliable performance and safety from hazardous operating conditions. It can be used for a wide range of applications, from machine vision systems to medical systems.
