GH 11000

Product catalog summary

Overview: The GH 11000 is a loop-powered isolator designed to provide galvanic separation for 0(4) ... 20 mA standard signals. It ensures high accuracy in transferring measurement signals while preventing interference voltage carry-over and suppressing parasitic noise. The device features a low voltage drop of 2.3 V and does not require an additional power supply, as it derives auxiliary power from the input signal.

Key Features:

Galvanic isolation between input and output to prevent erroneous measurements due to parasitic voltages or ground loops.
No additional power supply needed, reducing installation costs and line influences.
Extremely slim design with 1- and 2-channel versions, occupying only 3.1 mm DIN-rail per channel.
Protective separation according to EN 61140, ensuring safety for service personnel and downstream devices.
High reliability with no maintenance costs and a 5-year warranty covering defects.

Technical Data:

Input: 0(4) ... 20 mA signal, operating current < 200 μA, voltage drop approx. 2.3 V at 20 mA, overload ≤ 50 mA, 30 V.
Output: 0(4) ... 20 mA signal, load 600 Ω, cut-off frequency -3 dB at 100 Hz, response time T99 7 ms, residual ripple < 10 mVrms.
General: Transmission error < 0.1% full scale, load error < 0.05% of measured value per 100 Ω load, temperature coefficient < 100 ppm/K, test voltage 3 kV AC, 50 Hz, 1 min. between all circuits.
Environmental: Operating temperature -25 to +70 °C, transport and storage temperature -40 to +85 °C, EMC compliance with EN 61326–1.
Construction: 6.2 mm housing, protection class IP 20, mounting on 35 mm DIN rail according to EN 60715, weight approx. 70 g.

Connection Details: The device uses captive plus-minus clamp screws with a maximum wire cross-section of 2.5 mm² / AWG 14, stripped length of 6 to 8 mm, and screw terminal torque of 0.8 Nm / 7 lbf in.

Product Line: Available in 1-channel (GH 11010 S) and 2-channel (GH 11020 S) versions.

Catalog excerpts

The loop-powered isolator GH 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 GH 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 GH 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. • 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
