Passive Isolator DH 11000Separation of 0(4) ... 20 mA Standard Signal CC The input loop-powered isolator DH 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. 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 1 1 000 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 1 1 000 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. • 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 EN 61140 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) DRAGO Signal Converter - Isolation Amplifiers - www.drago-automation.de
