Programmable oscillators are a type of processor-controlled oscillator that offers a greater degree of frequency accuracy, stability and reliability than conventional oscillators. The SIT3809AC-C-18EX is a rugged, high-grade programmable oscillator designed for hazardous environments. It is designed to withstand extreme temperature, shock, and vibration in a variety of applications that require reliable frequency control.
Application Field
The SIT3809AC-C-18EX is designed for use in hazardous industrial environments both in the US and internationally, offering highly reliable frequency control against these challenges. Some examples of applications are:
- Automation and motor control
- Avionics equipment
- Monitoring, measuring and control systems
- Industrial instrumentation
- Onboard computers
Working Principle
The working principle of the SIT3809AC-C-18EX is similar to that of a standard oscillator, but instead of relying on the user to set or adjust frequencies, it has an internal processor that can be programmed to change frequencies based on external commands or other signals. This allows the user to set up and adjust frequencies in a matter of seconds, rather than having to manually adjust them.
The device is composed of two main sections: the main circuit board and the processor. The main circuit board contains the oscillator itself, transistors, resistors, and other components, as well as several user-set frequency settings. This can be adjusted with the use of soldering or by applying voltage to the pads on the main circuit board.
The processor receives commands from external sources or from the internal settings, and uses this information to automatically adjust the frequency and the time the oscillator takes to toggle between the two states. This allows the device to have a greater degree of precision and accuracy than a standard oscillator, as the internal processor can adjust its settings quickly and precisely.
The device also has an adjustable power supply, which can be set to any required input voltage or frequency. This allows the device to be used in a variety of applications, from low voltage and frequency systems to high voltage and frequency systems.
Overall, the SIT3809AC-C-18EX is an advanced, reliable, and programmable oscillator designed for use in various industrial and military applications. It offers greater accuracy and reliability than conventional oscillators, as well as a wider range of frequency settings, making it ideal for applications that require precise and reliable frequency control.
