G4 I/O family
The G4AD25 analog input module provides a single channel of optically isolated voltage-to-digital conversion. Nominal voltage input is 0 to 100 VDC or VAC, but with an over-range capability to 263 volts, the G4AD25 may be used to monitor 120/240 volt AC/DC and 12/24/48 volt AC/DC system voltage.
