Working Principle

The 84872142 is designed to measure current and voltage in an electrical system. It features a linearized sensor interface and high-precision AC/DC signal sampling technology. To measure the current, the module uses a low-cost current transformer. The current transformer is connected to a precision voltage-to-frequency converter, which converts the current signal into a frequency signal. This signal is then sent to the microcontroller, which calculates the current and outputs it to the LCD display. To measure the voltage, the module uses a high-precision voltage divider module. The voltage divider module is connected to a precision voltage-to-frequency converter, which converts the voltage signal into a frequency signal. This signal is then sent to the microcontroller, which calculates the voltage and outputs it to the LCD display.

The 84872142 is also capable of alerting users when an over/under voltage or current condition has been detected. It does this by activating relays that can be connected to alarms. The module is pre-set with over/under voltage and current thresholds, allowing users to customize the alarm to fit their needs.

Conclusion

The 84872142 is a high-precision Relay Output module designed for monitoring the current and voltage of electrical systems. It offers an accuracy of ±2%, and features multiple inputs and outputs, making it easy to measure and trigger alarms in response to over/under voltage and current conditions. The 84872142 is an ideal choice for monitoring generator and load power, power distribution and transmission, power quality, and motor control, allowing users to optimize their power system and reduce energy costs.
