The 84871306 is a monitoring device used for current and voltage applications with a relay output. It is primarily designed for use in automated manufacturing and process control systems. The unit is designed to detect fluctuations or transients in current or voltage levels and trigger an output signal, typically a relay, to react to the change.

In terms of the current application, the 84871306 can detect when there is a build-up of current exceeding a set limit and quickly react. This reaction could be in the form of an alarm or a system stop to prevent possible damage occurring. The device can also be used to measure voltage and react when the voltage level is too high or too low. Some of the typical applications of the 84871306 include thermal overload protection, overload protection, and motor overload protection, among many others.

The 84871306 also has a working principle, which dictates how the device operates. In general, the unit has two primary components, a pulse transformer and a thyristor. The pulse transformer is connected to the main power source and produces a waveform with a variable frequency. This waveform is then sent through the thyristor, which provides the output signal. If the current or voltage exceeds the preset limit, then the thyristor switches on, which triggers the relay connected to the device. The relay then switches on or off, depending on the preset voltage or current.

The 84871306 is designed to provide a reliable and efficient way to monitor current and voltage and is suitable for a wide range of applications. It is easy to install and use, has a maximum switching voltage of 700 volts, and can be used in temperatures between -55 degrees C and 140 degrees C. The unit is a cost-effective way to monitor power and can help prevent damage to other connected devices.

In summary, the 84871306 is a device designed to monitor current and voltage levels with a relay output. It has a wide range of applications, is easy to install and use, and is cost-effective. It is suitable for use in automated manufacturing and process control systems where it can detect fluctuations or transients in current or voltage levels and trigger an output signal.
