IsoPAQ-612 2-channel isolating INOR current signal isolator

Description

The IsoPAQ-612 two-channel INOR isolation current signal isolator with 0(4)-20 mA signal isolation loop provides galvanic isolation for standard 0(4) … 20 mA signals, while transmitting the measurement signal to the output with a high degree of accuracy.

The unit avoids interference voltage transmission and effectively suppresses parasitic noise. The very low voltage drop of 2.3 V and the high degree of accuracy combine to make the IsoPAQ-611 the first choice in system design.

The isolator does not need any additional power supply, as the auxiliary power is extracted from the input signal without distorting it. This not only saves costs during installation, but also increases reliability. Intelligent design and the consequent avoidance of highly integrated components ensure extremely long life and reliability – without any falsification of the measurement signal.

Main features of IsoPAQ-612

• galvanic isolation between the input and output:
  protection against erroneous measurements due to a voltage parasitic or earth loop
• no power supply required:
  Cost savings, as wiring is reduced and duct impacts are omitted
• Extremely slim design:
  the extremely thin 6.2 mm housing combined with very low self-heating allows a tight fit
• safe separation according to EN 61140
  protects service personnel and downstream equipment from unacceptably high voltage
• maximum reliability
  no maintenance costs
