5.5.11 Pro-AIn-32/16 Rev. B
To this module you find an improved successor module
(see page 63).
The analog input module Pro-AIn-32/16RB has a 16-bit ADC and a program-
mable gain amplifier (PGA). It has 32 single-ended or 16 differential inputs
(software selectable). The inputs are connected on a 37-pin DSUB socket. The
module can be combined with Pro-TC and Pro-PT modules.
The module Pro-AIn-32/16RB is equipped with an input voltage range of ± 10V
and a gain amplifier, programmable by software to 1, 2, 4 or 8. The adjustment
of gain and offset is made by software (see
ware").
