Pro II: Analog Input Modules
Pro II-AIn-32/18-D Rev. E
ADwin
5.5.2 Pro II-AIn-32/18-D Rev. E
Analog input module Pro II-AIn-32/18-D Rev. E with an 18-bit ADC, 32 differ-
ential inputs and a programmable amplifier (PGA). The module can be com-
bined with amplifiers, Pro-TC and Pro-PT modules.
The variant Pro II-AIn-32/18-D-TiCo Rev. E additionally provides a freely pro-
grammable
TiCo
processor, 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.
The module has 32 single-ended or 16 differential inputs (software selectable).
The inputs are equipped with a 37-pin D-Sub female connector; for pin assign-
ment see fig. 40 and 41.
After power-up the module is set to 16 differential inputs.
The module Pro II-AIn-32/18-D 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").
Ex works the inputs are connected to the ground of the Pro device. Alterna-
tively a GND level signal–common for all inputs–can be connected to one of
the AGND pins. The ground connection to the Pro device should be split up,
by switching the DIL switch (see fig. 42) to position
GND
LIFT
.
Do not run the module without ground connection.
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.
