Passive Isolator DH 11000

Separation of 0(4) to 20 mA Standard Signal

The input loop-powered isolator DH 11000 provides galvanic sepa­ration for 0(4) to 20 mA standard signals, while trans­ferring the measure­ment signal to the output with a high degree of accuracy.

  • 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, 1- and 2-channel versions
    Only 3.1 mm DIN-rail per channel
  • Protective Separation acc. to EN61140
    Protects service personnel and downstream devices against impermissibly high voltage
  • Maximum reliability
    No maintenance costs
  • 5 Years Warranty
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The input loop-powered isolator DH 11000 provides galvanic sepa­ration for 0(4) to 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 DH 11000 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 DH 11000 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.
