ADwin
5.5.9 Pro-AIn-8/16 Rev. B
To this module you find an improved successor module
(see
).
The analog input module
has a 16-bit ADC, 8 differential
inputs and a programmable gain (PGA). The module can be combined with
amplifiers, filters, Pro-TC and Pro-PT modules.
The inputs are available with the following connectors:
– Pro-AIn-8/16: shielded LEMO-sockets, CAMAC European norm.
– Pro-AIn-8/16-D: DSub socket 37-pin.
The module
is an advanced development of the module
Pro-AIn-8/16 with an input voltage range of ± 10V and a gain, programmable
by software of 1, 2, 4 or 8. The adjustment of gain and offset is made by soft-
ware (see
chapter 6.3.1 "Calibration per Software"
