UJA1069TW24/5V0:51 Application Field and Working Principle

This article focuses on the application field and the working principle of UJA1069TW24/5V0:51, a highly reliable isolated amplifier with integrated insulation detection, designed for industrial use. It is suitable for the isolation, damping and amplification of sensor signals in industrial process measurement technology.

Application Field

UJA1069TW24/5V0:51 is mainly used in the process control of chemical, petrochemical and oil & gas industries, as well as test and measurement, robotics and industrial automation applications. The device can be used as an interface between industrial measurement technology, such as an analyzer or converters, and a PLC or fieldbus system. The product can be connected to many process sensors and encode analog signals into digital signals. It can also be used in multi-channel process monitoring systems, especially in safety-critical environments.

Additionally, UJA1069TW24/5V0:51 also provides a suitable platform for interfacing complex systems with potentials beyond 24V or 48V. This is important because the transfer of hazardous signals over large distances can be tricky. The amplifier is designed for insensitive grounded or potential dividers which can be used for reliable 4-20mA-signal transmission.

Working Principle

UJA1069TW24/5V0:51 has an active output and a passive input ground part. The power supply is divided into the active side and the passive side. The amplifier transfers the signals in a balanced way between the different ground potentials on both sides. The input circuit is decoupled capacitively so that the variation of the passive side ground potential is not transferred to the active side. The amplifier contains all necessary protection features, such as the isolation detection, overvoltage and short circuit protection, which is extremely important in process measurement technology.

The harmonics, generated when sending signals over longer distances or in complex systems, can often cause a significant amount of undesirable noise. To ensure low interference and reliable communication over large distances, UJA1069TW24/5V0:51 has a high common mode rejection ratio, as well as a wide frequency response. Additionally, the device is equipped with an integrated security mechanism, which can detect excessive insulation resistance and protect the device from destruction due to insulation faults.

Summary

UJA1069TW24/5V0:51 is a highly reliable isolated amplifier with integrated insulation detection. It is mainly used in the process control of chemical, petrochemical and oil & gas industries, as well as test and measurement, robotics and industrial automation applications. The amplifier transfers the signals in a balanced way between the different ground potentials on both sides and contains all necessary protection features. The product also has a high common mode rejection ratio and a wide frequency response, as well as an integrated security mechanism.
