gle/ISObox


• 4 or 8 high-voltage isolated channels.
• 500 VDC insulation voltage input/output.
• Selectable attenuation of 1, 10 or 100.
• BNC I/O connectors.
• Light weight slim package.

gle/ISObox allows users to convert a normal voltage input channel of a data acquisition system into a Galvanic insulated input. Each single-ended input channel of the gle/ISObox is in fact capable to support an input/output and among channels common mode voltage of 500VDC.

Furthermore, in addition to the ground loops elimination, the use of gle/ISObox provides a selectable attenuation factor of 10 or 100. This means a maximum input voltage of 100 or 1 kV(*). Of course a 1 to 1 attenuation ratio is also available.

Each input of the gle/ISObox is single-ended connected through a BNC connector to a 1 MW resistor independently from the selected attenuation level. Moreover channel protection is accomplished by means of a micro fuse and a voltage connected switched-off to the signal sources, the attenuation is automatically set on the maximum value (100), independently from the actual set attenuation, enhancing the protection grade when the unit is not in use.

The basic gle/ISObox configuration fits 4 or 8 channels in a light weight slim box,  with BNC connectors both for inputs and outputs..

The gle/ISObox may be powered by 9…36V  DC voltage, while an AC 110/220V 50/60Hz adapter is available as option.

(*) 1000V is applicable only for a short time; the internal voltage divider allows a maximum power dissipation of 250 mW. This means a maximum continuous voltage of 500 V.
