OPTO 22 G4AD3 Analog +4 to +20 mA Input Module

OPTO 22
The G4AD3 module provides a single channel of transformer and optically isolated current-to-digital conversion. The nominal inputrange is 4 to 20 milliamps with an under/over range capability from less than 3 milliamps to greater than 35 milliamps. One of the uniquefeatures is that the isolated loop supply can be provided by the G4AD3. This eliminates the need for the user to provide the loop supply(typically 15-48 V) and also saves the associated wiring, barrier strips, etc. The G4AD3 module also includes complete electrical channel to-channelisolation which eliminates any ground loop problems. Modules plug into an Opto 22 Modular controller or an analog I/O brickand are secured by a captive screw. The field connections are made to the terminal strip located on the Brick base or controller I/O board.
