Sub modules
The data acquisition sub modules can be plugged into the module slots (connectors).
Max. 16 channels can be operated within a device. Grouping is done logically and for
different signal types.
Protection measures require that high voltages and lower voltages are not to be mixed
within a single connector. The design of the ibaPADU-16-M supports this feature (refer
to connectors). Normally AC currents and voltages are measured in groups of 4. Mixing
of different modules within a device is allowed in accordance to the requirements of
these groups.
The device is configured and manufactured according to the selected modules. For ad-
ding or replacing a module the device cover must be opened.

8.1.1
Analog Inputs ±10 V DC
Inputs for DC ±10 V are used to measure analog signals of the control system and the
DC protection.
Inputs scalable to physical dimensions (2pt. SW scaling)
Max. 16 inputs are represented within the HARTING connector X5. No signal mixes
with other types of signals are allowed within X5. X5 is always available at the device
while the other connectors are mounted only if the appropriate modules are there.
8.1.2
Analog Inputs 110 V AC, 220 V AC, 380 V AC
These inputs transform these values into ±10 V DC ranges of the measuring circuitry
and are designed for the direct connection of the voltage transducers.
Each 4 of these inputs are represented within one HARTING input connector in groups
of 4 inputs. That means if only 4 of these inputs were selected only 1 HARTING con-
nector is present for these inputs.
8.1.3
Analog Inputs 1A AC, 5A AC, 1A AC/100A DC (100 A for 1 sec)
These inputs are to be designed to accept the signal of the current converter and trans-
form this signal into the DC ±10 V range of the measuring circuitry. The contained DC
current part within the signal is also to be measured.
Every 4 of these inputs are represented within one HARTING input connector in groups
of 4 inputs. These connectors in addition short-circuit the current line if connector is
pulled out (disconnected) to protect the connected current transducers. That means too
if only 4 of these inputs were selected only 1 HARTING connector is present for these.
8.1.4
Digital Inputs 8DI 24V, 8DI 110V, 8 DI 220V
There are two different input modules available with 8 channels each. 2 modules can
be used at the same time. 8 channels are represented within one Phoenix connector.
8.1.5
Other Modules
Due to the modularity of the device other modules can be designed on request (As ICP,
Speed Pulse counters etc. are to be designed for other applications too – please con-
tact iba for more information).
