This module has eight differential inputs and an expansion port. Each input can be individually configured for either voltage or current. Each of the input channels also has individual user scaling. On-board load resistors are included for normal input current ranges up to Ç 40 mA. If other current ranges or different resolution is required, external resistors may be used. Standard system configurations for Ç 10 volts and 4 to 20 mA are available. These, and other lower input ranges, can be scaled to engineering units with the user scaling feature.
