    Product Description

    Nominal input range: 4 to 20 mA. Over/under range: 3 to 35 mA. Module Input Impedance*: 414 Ohms. Loop supply: 28 VDC nominal. Accuracy**: 16 µA** Accuracy figure requires use of gain and offset commands.. 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. Module Input Impedance*: 414 Ohms* - This is the equivalent impedance for the G4AD3 at full scale (20mA). The equivalent impedance is calculated by using the following formula: Equivalent impedance = 249 Ohms + 3.3V/0.02A = 414 Ohms The module has an internal resistance of 249 Ohms in series with a 3.3V zener diode.
