Additionally, it has an onboard programmable counter, which can be used to generate trigger signals for synchronous operations.

Working Principle

The 8N3DV85BC-0126CDI utilizes a quartz oscillator circuit to generate stable and accurate timing. The oscillator circuit is powered by a quartz crystal, which undergoes mechanical vibration at a specific frequency. The frequency is then divided and regulated by a programmable divider circuit to produce a regular and reliable clock signal, which can be used to generate pulses of different width.

The programmable divider circuit consists of a counter, an amplifier, and a logic circuit. The counter continuously counts the number of cycles in the quartz oscillator\'s output. When the counter reaches its programmed limit, the amplifier triggers the logic circuit to reset the counter. This process is repeated continuously, forming a pulse train at regular intervals. The pulse train can be used to generate triggers for synchronous devices, such as motors, solenoids, and relays.

The 8N3DV85BC-0126CDI also features an automatic calibration circuit (ACC) to maintain a high level of accuracy. The ACC periodically adjusts the counter\'s count rate to keep the output frequency within the specified tolerances. This feature ensures that the output frequency remains stable over a wide range of operating conditions.

Conclusion

The 8N3DV85BC-0126CDI is a powerful programmable timer and oscillator that is suitable for timing, battery-backup, and pulse-width modulation applications. It is designed for easy integration and is immune to electrical interference. It is also capable of maintaining a high level of accuracy with its automatic calibration circuit. Therefore, the 8N3DV85BC-0126CDI is a reliable and versatile choice for clock and timer applications.
