2 Introduction
The ibaPADU (Parallel Analog Digital Unit) device family is designed for data acquisition
of analog and digital signals. The new models ibaPADU-8AI-U and ibaPADU-8AI-I pro-
vide 8 digital inputs and 8 analog voltage or current inputs and replace previous devices.
ibaPADU-8AI-U (voltage inputs) replaces the following previous devices and integrates
the known functions in one device:

ibaPADU-8 (order no. 10.120000)

ibaPADU-8-F1 (order no. 10.120001)

ibaPADU-8-60 (order no. 10.120006)

ibaPADU-8-HI (order no. 10.120010)

ibaPADU-8-HI-F1 (order no. 10.120011)

ibaPADU-8-HI-25 (order no. 10.120014)

ibaPADU-8-HI-60 (order no. 10.120015)
Different device modes, which provide the device specific properties of the previous de-
vices like measuring range, input impedance and filters, are set by means of a rotary
switch. The measuring range of the inputs is selectable in three stages: ±10 V, ±24 V or
±60 V. An integrated analog low-pass filter reduces possible disturbances of the signals.
A digital antialiasing filter and a digital low-pass filter are additionally activated depending
on the device mode. The filter characteristics may differ from the previous devices.
ibaPADU-8AI-I (analog current inputs) provides an input level of ±20 mA and replaces
this device:

ibaPADU-8-I (order no. 10.120020)
If no special reference to a device is made in the following text the devices are named
as ibaPADU-8AI in general and the description applies to both devices.
Each channel of both models is galvanically isolated and equipped with its own A/D con-
verter in order to measure simultaneously all channels.
The existing ibaFOB cards and the I/O configuration in ibaPDA can remain in use.
Up to 8 devices can be linked in a daisy-chain on the fiber optics link. In ibaPDA, the
synchronization of the data recording of all devices on the line is ensured within an ac-
curacy of a millisecond. The data acquisition cycle for all devices in one line is 1 ms. Up
to 64 analog and 64 digital signals are transmitted per cycle.
Each device provides a RJ11 jack for the connection to a notebook with an ibaCom-
PCMCIA-F card. Thus, it is possible to carry out measurements in parallel at the RJ11
jack without affecting the data transmission on the fiber optic cable.
