Pro II: Analog Input Modules
Pro II-AIn-8/18 Rev. E
ADwin
5.5.1 Pro II-AIn-8/18 Rev. E
Analog input module Pro II-AIn-8/18 Rev. E with an 18-bit ADC, 8 differential
inputs and a programmable amplifier (PGA). The module can be combined
with amplifiers, Pro-TC and Pro-PT modules.
The module can be ordered in the following variants:
TiCo processor
The variants Pro II-AIn-8/18-xxx-TiCo additionally provide a freely programma-
ble
TiCo
processor with 28 KiByte data memory and 28 KiByte program
memory, which has access to all inputs of the module. Find more information
about use and programming of the
TiCo
processor in the manual
TiCoBasic
.
If you store a
TiCoBasic
program in the
TiCo
bootloader, the program is auto-
matically loaded into the
TiCo
processor and started on power-up. Thus, the
module can run on its own and independently from the CPU module of the
ADwin-Pro II
system.
low pass filter
The variants Pro II-AIn-8/18-xxx-LP contain an input filter, a 4th grade low pass
of Butterworth type. According to the variant the frequency is set to 5kHz,
10kHz, or 50kHz.
The inputs are available with shielded LEMO connectors (1-pole, CAMAC
European norm) or a DSub socket 37-pin, see fig. 36.
The module Pro II-AIn-8/18 Rev. E has an input voltage range of ±10V and a
software selectable gain of 1, 2, 4 or 8. The adjustment of gain and offset is
done by software (see chapter 6 "Calibration").
The module includes a sequential control, which can read measurement val-
ues from several or all input channels sequentially.
The module can control an upper and lower limit for each channel separately.
