G4 I/O family
The G4AD3 module provides a single channel of transformer and optically isolated current-to-digital conversion. The nominal input range is 4 to 20 milliamps, with an under/over-range capability from less than 3 milliamps to greater than 35 milliamps.
One of the module’s unique features is that the isolated loop supply can be provided by the G4AD3. This eliminates the need for you to provide the loop supply (typically 15-48 V) and also saves time and money for the associated wiring and barrier strips. The G4AD3 module also includes complete electrical channel-to-channel isolation, which eliminates ground loop problems.
