5.5.8 Pro-AIn-8/16 Rev. A
To this module you find an improved successor module Pro-AIn-8/16 Rev. C
(see page 59 ).
Analog input module Pro-AIn-8/16 Rev. A with a 16-bit ADC and 8 differential
inputs. The module Pro-AIn-8/16 Rev. A has options for combination with ther-
mocouples, filters and PTC-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 input voltage range of the ADC can be adjusted by jumpers (see below).
