Introduction

The 84872301 is an advanced line monitor designed for three phase installations with several input options and relay outputs to handle complex monitoring tasks. It is designed for a wide range of applications, from monitoring electric motors and pumps to industrial equipment. It can be used to monitor single or three phase circuits and sense phase loss, overvoltage or undervoltage, voltage unbalance, overcurrent and more. It has a built-in digital display that can display many types of parameters such as voltage, current and power. It can also be used for remote monitoring applications using its serial communication port.

Application fields

The 84872301 is a versatile and very capable product that can be used in a multitude of applications. It can be used to monitor electric motors, pumps, compressors, and other industrial equipment. It is also useful for applications that require monitoring of single or three phase circuits, such as solar power plants, wind power plants, hydroelectric plants, and others. It is especially suited for monitoring critical applications such as power lines, electrical control systems, and factory production lines. It can also be used in remote monitoring applications using its serial communication port.

Working Principle

The 84872301 is designed to continuously measure the voltage, current, and power values in a three phase installation. It features several input options, including direct voltage and current inputs, as well as an analog output option. It also has a built-in digital display that can display many types of parameters such as voltage, current and power.The 84872301 is designed with an internal control logic block that enables the input values obtained from the user to be filtered and processed in order to signal the board\'s output relays in case of an alarm condition. The board\'s relays can be programmed to activate a dedicated warning signal or to switch off the internal current flows and stop the monitored installation when necessary.The 84872301 also includes a serial communication port, so that it can be used in remote monitoring applications such as power line monitoring and control. The serial communication port can be used to monitor the measured parameters and send and receive data from a remote monitoring station.
