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.

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. If there is a rule to ground the device, connect the device to the ground (grounding
screw X29).
3. 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 connections X10 and X11
X11 (RX): FO input
X10 (TX): FO output
The X10 output has all data of the device itself and the data from all previous devices.
Chaining is done when X10 of a device is connected to X11 of the next device. The last
output must then be connected to a fiber optic input of the ibaFOB card. Connecting and
disconnecting of devices on the fiber optic links is allowed at all times. Interrupting the
fiber optic link leads to missing data for the time period of the interruption.
Maximum distance of fiber optic connections
The maximum distance of fiber optic connections between 2 devices depends on various
influencing factors. This includes, for example, the specification of the fiber (e.g.
62.5/125 μm, 50/125 μm, etc.), or the attenuation of other components in the fiber optic
cable plant such as couplers or patch panels.
However, the maximum distance can be estimated on the basis of the output power of
the transmitting interface (TX) or the sensitivity of the receiving interface (RX). A model
calculation can be found in chapter 10.3.
The specification of the transmitter's output power and the receiver's sensitivity of the
fiber optic components installed in the device can be found in chapter "Technical data"
10.1 under "ibaNet interface".
7.3.2 Power supply X14
The device requires an external DC 24 V ±10% power supply (unregulated). The oper-
ating voltage should be run through the provided 2-pin Phoenix threaded coupling con-
nector. If desired, you can order DIN rails or plug-in power supply units from iba.
7.3.3 Analog / digital inputs
Connection diagram
It is possible to connect 8 analog input signals and 8 digital input signals, each bipolar
and electrical isolated. Each channel is connected by means of two-wire connection. Due
to the reverse polarity protection, the measuring signal is indicated logically correct, even
if the connection is polarity-reversed.

7.3.4 Grounding screw X29
Proper connection of cable shielding to the device should be ensured. The shield con-
nector (M6 screw) found on the bottom of the device should be connected with any total
shield that serves for all sensor cables. Use a M6 cable lug for the connection.
Important note!
Connect shield on one cable side only to avoid ground loops
!
Always ground the DIN rail on which the device is installed
!
7.3.5 Ethernet interface X12
The Ethernet interface on the bottom of the device is used to load a new firmware ver-
sion.
The Ethernet interface is set as default to the IP address 192.168.1.1.
Note
Please contact iba regarding loading new firmware. You will get the require
d files and
further information.
Important note
In normal operation mode the
Ethernet cable must not be connected.
Procedure for update via FTP connection
1. Connect the computer and the device with a network cable. Computer and device
must be in the same network.
2. Assign a static IP address to the interface of the computer from which you want to
connect via FTP. The address has to be from this range:
192.168.1.n with n = 2…254 and the subnet mask 255.255.255.0
3. Establish an FTP connection to the device. You may use an FTP client or the Win-
dows File Explorer. In both cases, the address is “192.168.1.1” and the user is “anon-
ymous” without any password.
4. Please note that you have to configure the passive mode in the FTP client. Example
Windows File Explorer:

ibaPADU-8AI-U/-8AI-I
Manual
Issue 1.6
17
The file "Event.log" is always present by default and contains various device infor-
mation, such as the current firmware version.
5. Rename the update file “padu*_v*.iba” to “padu*_v*.iba.ready” and copy it via the
FTP connection to the directory on the device.
6. When the file is copied, the update is started immediately and the LED L1 of the
device starts flashing fast.
7. The device will automatically restart when the update is complete. The FTP client can
now be closed.

7.3.6 RJ11 connection X9
A notebook equipped with an ibaCom-PCMCIA-F card can be connected at the RJ11
jack at the bottom of the device.
Thus, it is possible to carry out measurements in parallel at the RJ11 jack without affect-
ing the data transmission on the fiber optic cable.
7.4 Operating elements
7.4.1 Rotary switch S1
S1 is used to set the device address (1 … 8). Each address represents 8 A + 8 D chan-
nels.
Important note
The position of the address switch S1 must not be “0, 9

the link is
broken

8 System integration
8.1 Homogeneous ibaPADU-8AI chain
Up to 8 devices can be connected in a line topology. The outputs of the devices are to
be connected with the input of the following devices until all devices are interconnected
and the last device is connected to the ibaFOB card. All addresses (1...8) within a chain
must be unique. If 2 devices carry the same address the subsequent device in the fiber
optic link overwrites the content of the previous device.
Figure 3: ibaPADU-8AI chain
Principle of the data packages in a FOB telegram
Each box (address) contains 8 analog + 8 digital signals. The device address determines
where the data are placed in the telegram. Therefore, the position of a device in the chain
is independent of the address setting.
Figure 4: Principle of the data packages
