IsoPAQ-611 single-channel isolator with loop for separating INOR current signals

Description

The IsoPAQ-611 single-channel isolator with INOR current 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. Intelligent design and the consequent avoidance of highly integrated components ensure extremely long life and reliability – without any falsification of the measurement signal. 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.

Main features of IsoPAQ-611

• 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 for a tight installation
• safe separation according to EN 61140:
  protects service personnel and downstream equipment from unacceptably high voltage
• maximum reliability:
  no maintenance costs
