Passive Isolator DH 1000 – Separation of 0(4) to 20 mA Standard Signals


The loop-powered isolator DH 1000 provides galvanic separation for 0(4) to 20mA 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 compact design, 1- and 2-channel versions
    Only 6.3 mm DIN-rail per channel
  • High accuracy
    No falsification of measured signal
  • Protective Separation
    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)

In this way, the unit avoids interference voltage carry-over, effectively suppressing interference. The very low drop voltage of 2.0 V, a high level of accuracy and a compact design all work together to make the DH 1000 the first choice in system design.

The slim housing with 12.5 mm width for one or two channels saves space in your switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly. The DH 1022 requires only 6.3 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.

To protect both maintenance personnel as well as downstream equipment against impermissibly high voltages, the DH 102X offers Protective Separation with a test voltage of 4 kV AC. The DH 1000 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.
