Loop-Powered Isolator D6H 11000

Separation of 0(4) ... 20 mA Standard Signals

With the Loop-Powered Isolator D6H 11000 DRAGO is extending its offer on high-accuracy and high-reliable components of the interface technique.

  • 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 3.0 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

The loop-powered isolator D6H 11000 provides galvanic separation for 0(4)...20 mA standard signals, while transferring the measurement signal to the output with a high degree of accuracy. In this way, the unit avoids interference voltage carry-over, effectively suppressing interference. The very low drop voltage of 1.9 V, a high level of accuracy and a compact design all work together to make the D6H 11000 the first choice in system design.

The slim housing with 6.0 mm width for one or two channels saves space in your switch cabinet and facilitates by the practical pull-spring terminal blocks the assembly. The D6H 11020 requires only 3.0 mm DIN-rail space per channel.

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 D6H 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.
