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
