2 Introduction
The ibaPADU-4-AI-U compact device has been developed for capturing and recording
fast analog signals. The sampling rate can be adjusted freely up to 100 kHz max. The
device offers 4 electrically isolated voltage inputs. The measuring ranges of these inputs
are adjustable in several stages from ±250 mV up to ±24 V.
Antialiasing filters limit the bandwidth of the input signal in order to reduce disturbances.
A digital filter can be activated per channel together with an analog antialiasing filter. The
digital antialiasing filter is adjusted automatically to the configured sampling rate.
The signals are converted internally and are available via the fiber optics (FO) interface.
By means of the ibaPDA online-data acquisition software, you can choose and configure
the signals conveniently. The communication between ibaPDA and ibaPADU-4-AI-U is
handled by the bidirectional fiber optic protocol 32Mbit Flex, which requires an I/O card
from the ibaFOB-D generation, e. g. ibaFOB-2io-D.
In brief
4 electrically isolated analog inputs
Input signal level ±250 mV; ±500 mV; ±1 V; ±2.5 V; ±5 V; ±10 V; ±24 V,
can be adjusted for each channel

Sampling rate of 100 kHz max. freely adjustable in a point-to-point connection
(if connected in a ring topology with 32Mbit Flex, max. sampling rate is 40 kHz)
Real parallel measured value acquisition by an A/D converter per channel
Antialiasing filters can be activated
ibaNet protocol 32Mbit Flex (FO)
Rugged design, easy mounting

6 Mounting and dismounting
6.1 Mounting
1. Locate the DIN rail mounting clip on the rear side of the device. Slowly push down
and in so that the bottom part of the mounting clips snaps onto the bottom part of the
rail and firmly fixes the device to the DIN rail.
2. Connect the 24 V DC power supply to the termination shown on the device. Ensure
that the polarity is correct prior to applying power. Then connect the device to the
ibaPDA system via a bidirectional FO cable.
6.2 Dismounting
1. Disconnect all external connections from the device.
2. Grasp the device with one hand firmly on the top side. With your free hand, grasp the
bottom of the device and push it lightly down.
3. After that pull the device and lift it up. With this action, the device should free itself
from the DIN rail.

7.3 Connections
7.3.1 Fiber optic cable connectors RX / TX
X11: Fiber optic reception interface (RX)
X10: Fiber optic transmission interface (TX)
Data is transmitted in 32Mbit Flex mode. ibaPDA requires a fiber optic card of the
ibaFOB-D family to receive and transmit data.
The fiber optic ports and transmitters are the physical base for a simple send-and-receive
connection to an ibaFOB card. The ports are designed for cables with 62.5/125 µm multi-
mode fibers and ST couplings which are available at iba too.
7.3.2 Power supply
The device requires an external DC 24 V ±10% power supply (unregulated) and should
be operated at a maximum of 0.4 A. The operating voltage should be run through the
provided 2-pin Phoenix threaded coupling connector. If desired, you can order DIN rails
or plug-in power supply units from iba.

8 System integration
8.1 Point-to-point connection
Figure 5: Point-to-point connection with ibaPDA PC
The device is connected to the ibaFOB-D card in the ibaPDA PC via a bidirectional FO
line to transfer configuration and process data. ibaPDA detects automatically the con-
nected device.
The maximum sampling rate of 100 kHz is only possible with a bidirectional point-to-point
connection to ibaPDA. If several devices are to capture at 100 kHz, each device requires
a bidirectional connection to an ibaFOB-D card.
8.2 Ring topology
Figure 6: Ring topology
Up to 15 devices can be connected to a ring. Configuration and process data are trans-
mitted in the ring.
Other 32Mbit Flex-enabled iba devices can be integrated into the ring as well. The de-
vices in the ring are addressed via the S1 rotary switch.
The amount of data per participant is allocated dynamically. According to the number of
analog and digital signals configured in ibaPDA and the configured timebase the amount
of data is calculated by ibaPDA. The maximum total data rate is determined by the fiber-
optic links and must be divided through the number of devices and the amount of data
per device. A reference value is approx. 3000 Bytes per ms (amount of data per analog
channel: 2 Bytes). The devices can work with different cycle times, however the cycle
time must be an integer multiple of the smallest cycle. If the maximum data rate is ex-
ceeded, ibaPDA displays an error message and recommends increasing the timebase
or decreasing the amount of data. A sampling rate of 100 kHz cannot be adjusted in a
ring, this is only possible with a point-to-point-connection.
