The input loop-powered isolator IsoPAQ-611 provides galvanic separation for 0(4) … 20 mA standard signals, while transferring the measurement signal to the output with a high degree of accuracy.
The unit avoids interference voltage carry-over and effectively suppressing parasitic noise. The very low drop voltage of 2.3 V and the high level of accuracy work together to make the IsoPAQ-611 the first choice in system design.
Intelligent design and their consequential avoidance of highly integrated components result in extremely long service lives and reliability – without any falsification of the measurement signal.
The IsoPAQ-611 requires no additional power supply since the auxiliary power is obtained from the input signal without distorting it. This not only saves costs during installation, but also increases reliability.
