Intrinsically Safe Sensor Barriers
The G005 Galvanic Isolation Amplifier has been
designed specifically for use with Positek® G Series and H Series Intrinsically
Safe position sensors. The G005 provides a
regulated and resistively limited +5V dc power supply
required by Positek® IS sensors, and it can be connected in
three or five wire modes. The G005 has an input power supply range of 12 to 30 volts dc, making it suitable for a wide range of
hazardous area applications. The output of the G005 is factory configured to either 0.5 to 9.5V or 4-20mA and has a bandwidth of 4.7kHz, making it ideal for servo control loops.
