Application field

The 8N4DV85BC-0168CDI is used in a wide range of applications, from general machine control to telecommunications, industrial networking and more. Its precise timing and frequency control capabilities make it ideal for industrial, laboratory, and process control.The module can be used for precise timing and frequency control, aiding in the development and operation of precision timing systems. It is also used to control complex and precise frequencies, as well as for precise timing and control of frequency-dependent events, such as shunt, shuttle and triggering. Its multi-channel oscillator and selectable pulse width modulation (PWM) functions make it well suited for telecommunications and data signaling applications.

Working Principle

The 8N4DV85BC-0168CDI operates on the principle of pulse width modulation (PWM). A programmable logic block (PLB) is used to generate an output signal whose duty cycle is accurately programmed and controlled by the 8N4DV85BC-0168CDI module. The PLB controls the PWM output\'s duty cycle by constantly adjusting the pulse width.The pulse width modulation data is stored in the module\'s programmable registers. This data is continuously monitored by the processor and adjusted when required. In this way, the pulse width of the output signal is continually monitored and adjusted, providing precise timing and frequency control.The 8N4DV85BC-0168CDI module also provides latch-type outputs, which allow the PWM signal to be configured to either remain in its current state or switch to a new state after a defined time period. This feature allows for use in cyclic timer applications, where outputs are triggered at regular and/or random intervals. The module also includes open circuit outputs (OCO), allowing for application-specific behavior.

Conclusion

The 8N4DV85BC-0168CDI is a highly integrated programmable timer and oscillator module designed for a variety of industrial and commercial applications. It provides precise timing and frequency control due to its pulse width modulation and latch style outputs, enabling complex tasks such as cyclic timer, fast frequency ramping, or signal scanning. The 8N4DV85BC-0168CDI is a cost-effective solution to many timing and frequency requirements.
