Certified with IU2055 monitor module
Output EEx ia IIC
Device installation allowed in the area 2
Protected against polarity reversals
Tolerance 1%

General
The BGX2000 is a galvanic isolator specifically selected to be used between a conventional safe zone and a zone monitor module..

Application
Isolation of a current signal from fire detectors or similar sensors.
In this case, a voltage source can be connected at the terminals in the safe area.
The current passing through a passive sensor can be measured in the safe area with a series resistor (50 Min.).
When using a voltage source, the measuring resistance can also limit the current.

Applications
Each GBX2000 (4 terminals) functions as a DC current isolator with protection against polarity changes.
The input and the output are galvanically isolated from each other.
Designed for connection of fire detectors, smoke detectors, thermometers, etc.
Higher accuracy allows differentiation between resting state, fire alarm and short circuit currents in the safe area.
In many cases they can also be used to control I / P converters..
No separate power supply required.
Due to the limitation of the input voltage of 24 V, the maximum output will be 21 V.
