G4 I/O family
The G4DA3 provides a single channel of transformer and optically isolated digital-to-current conversion for 4-20 mA current loops. The isolated loop supply can be provided by the module, eliminating the need for you to provide the loop power supply (typically 15-48 V) and associated wiring, barrier strips, and so on.
This module also includes complete electrical channel-to-channel isolation, which eliminates troublesome ground loop problems.
