ADwin
5.3.4 Pro II-AIn-F-8/18 Rev. E
The analog input module
Pro II-AIn-F-8/18 Rev. E
has 8 Fast-ADC of 18 Bit
and 8 differential inputs. The inputs are galvanically isolated from each other
as well as from other modules.
The inputs are available with the following connectors:
– Pro II-AIn-F-8/18-L2: shielded LEMO-sockets, 2-pole, CAMAC Euro-
pean norm.
– Pro II-AIn-F-8/18-D: DSub socket 37-pin.
The module
Pro II-AIn-F-8/18 Rev. E
has input voltage range of ±10V. The
adjustment of gain and offset is made by software. (see
).
