ADwin
5.5.18 Pro-AIn-F-8/16 Rev. A
Analog input module Pro-AIn-F-8/16 Rev. A with 8 ADC (16 bit) and 8 differen-
tial inputs.
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.
For the accurate adjustment of offset and gain the potentiometers Ox and Gx
are available (
fig. 137 ); you find information about the accurate adjustment on
page 68 . The "x" of the potentiometer’s names are place holders for the num-
ber of the corresponding ADC. The potentiometer names are imprinted on the
board.
