PV70L16-23S

PV70L16-23S is a product of the automation industry with a variety of possible applications and a specific working principle. It is a bi-directional, high-accuracy, frequency-cycling analog input isolation amplifier. This product is designed to provide electrical isolation for precision voltage or current measurement and is suitable for both isolated loops and closed loops.

The input isolation amplifier’s working principle is based on the electromotive transduction of the Peltier effect. This principle is well illustrated in the input isolation amplifier construction comprising two thin parallel plates connected to thermoelectric heaters providing energy to the transducers and an isolation cell. The transducers-operate electrically by passing an alternating current between the plates, thereby producing an alternating voltage dependent upon the temperature difference. When the temperature difference is maintained constant, a constant voltage difference or thermal voltage is produced.

The PV70L16-23S is designed to have a wide range of applications ranging from general-purpose voltage and current measurements to automotive applications, data acquisition systems, motor control systems, and industrial process control systems. The product has a range of input voltages of-2.2, 5, 10, 15, and 30 V, allowing it to measure precision voltages and currents efficiently. Additionally, it features a frequency-cycling of 70kHz, which ensures a high-accuracy measurement within a wide temperature range. The PV70L16-23S is also designed to have an isolation range up to 3000 V, offering maximum safety against electrical shock in any application.

Another advantage of the PV70L16-23S is that it has two current pulse outputs to indicate the output level. This feature ensures that the system can quickly and accurately adapt to changing inputs without having to manually adjust the control parameters. Finally, the product comes with a line connection that offers superior stability and reliability, making it an ideal choice for harsh environments.

In conclusion, the PV70L16-23S is an ideal industrial instrument for high-accuracy voltage and current measurements. It is easy to use, highly accurate, and provides maximum safety with its input isolation. Plus, its two current pulse outputs make it especially easy to integrate with other systems.
