The 8N4DV85EC-0174CDI8 programmable timer, also known as a delay on release timer, helps optimize user performance in a variety of applications. With the ability to be triggered and reset externally, the versatile device is one of the most commonly used clock/timing oscillators on the market. Here, we’ll take a closer look at the 8N4DV85EC-0174CDI8 Programmable Timer’s application field and working principle.

Application Field

The 8N4DV85EC-0174CDI8 is used in a wide range of applications. This includes industrial and medical diagnostics, analytical instrumentation, test and measurement equipment, data transmission, vehicle electronics and parts of a system that require timing elements. In all cases, this programmable timer offers a preset value for the required delay and the external reset option for clock synchronizations.

One useful feature is the programmable cycle time which can be set from 0 to 255.0 μs. The cycle time setting can be adjusted for process optimizations and control in order to achieve longer cycle times. For example, in medical diagnostics, it can help in the filtering of false signals which may be caused by high electrical noise in the environment.

In data transmission, the 8N4DV85EC-0174CDI8 enables the delayed transmission of signals which have been interrupted by errors or disturbances in the transfer process. In the case of vehicle electronics, the programmable timer can be used for improved fuel efficiency by allowing the engine to perform faster and reducing the cycle time for faster acceleration.

Working Principle

The 8N4DV85EC-0174CDI8 is a resetable timer with an adjustable delay-on-release interval. The timer is triggered by an external signal applied to the trigger input, which can be either a positive or a negative going pulse. The output will then go low for a period of time that is determined by the cycle time setting.

The output will remain low until the external signal is removed, at which point the output will go high again and the delay period will begin. As the external signal is removed, the output will remain high for the set amount of time and then go low again to reset the delay. This cycle will keep repeating until the external signal is reapplied.

The cycle time setting determines the length of the delay after the signal has been removed. This can be adjusted by the user according to their specific application requirements and can range from 0 to 255.0 µs. The reset signal also has an on-chip switch for setting a reset threshold, which allows for further control over the programmable timer.

Conclusion

The 8N4DV85EC-0174CDI8 programmable timer is a versatile device suitable for a variety of applications. It is designed to be triggered and reset externally with an adjustable cycle time and a reset threshold switch for optimal performance. The easy to use device is one of the most commonly used clock/timing oscillators currently available on the market.
