IsoPAQ-611

1-channel Loop Powered Isolator for separation of 0(4)-20 mA Signals

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.

  • Galvanic isolation across input and output
    Protection against erroneous measurements due to parasitic
    voltages or ground loops
  • No power supply required
    Saving costs since wiring is reduced and line influences are omitted
  • Extremely slim design
    Extremely slim casing of 6.2 mm combined with very low self heating allow tight mounting
  • Protective Separation acc. to EN 61140
    Protects service personnel and downstream devices against
    impermissibly high voltage
  • Maximum reliability
    No maintenance costs
