5.5.11 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: shielded LEMO female connectors, CAMAC Euro-
pean norm.
– Pro II-AIn-F-8/18-L2: shielded LEMO female connectors, 2-pole,
CAMAC European norm.
– Pro II-AIn-F-8/18-D: D-Sub female connector 37-pin.
– Pro II-AIn-F-8/18-B: BNC connectors.
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 chapter 6 "Calibra-
tion").
The module can perform a simultaneous conversion on all channels using a
sequence control. This disburdens–compared to single measurements with
the instruction
P2_ADCF
–the processor module, which only reads and proces-
ses the converted measurement values. The conversion can be either trigge-
red periodically with regular time delays or by external event signals.
The module can control an upper and lower limit for each channel separately.
In order to use a channel as single-ended input, connect the input signal to the
plus pin and ground to the minus pin.

As ground connection the enclosure’s ground (PE) is available. All analog
inputs are galvanically isolated from enclosure’s ground.
With module versions -L2 (2-pole Lemo) and -D (D-Sub connector), the enclo-
sure’s ground is also available at the shield of the connectors.
