Page 5: Introduction
The AIGX requires a 14.5 - 30 V d.c. power supply; it has a 0 to 10 V d.c. analogue output which is related to pressure. The AIGX is compatible with Edwards Controllers. Alternatively, you can use an independent power supply and you can read the output signal with a voltmeter or analogue to digital converter. -
