PAD4
Caution!!!
Please read the risk assessment document before operating the potentiostat.
Prevent the inputs of the potentiostat from electrostatic discharge (ESD)! ESD may
damage the potentiostat. ESD-related damages are not covered by the warranty of
the potentiostat. The user must make sure to discharge his-/herself from any
electrical charge before touching the potentiostat (TIP: use grounded ESD-matts).
Maintain the maximum input voltage of the device and the selected voltage range.
Use electrically insulated thermocouples.
Do not expose the PAD4 card to heat.

1Introduction
The PAD4 was designed for the investigation of stacked objects like batteries and
fuel cells, where the impedance, defined by one common current through the
object, but several voltages accessible on several taps must be acquired in parallel.
Compared to the usual solution with multiplexers like the PMUX series, the PAD4
has the advantage of real parallel acquisition, saving measurement time and
avoiding time lags between the acquisitions of different channels.
PAD4 is a plug-and-play card for an extension slot of the Zennium Pro/X. It allows
connecting four different potential sense inputs for parallel impedance
measurements.
With four PAD4 add-on cards up to 16 channels synchronous measurements can
be done in parallel to the main channel.
The Zennium Pro can control one PAD4 add-on card with 4 additional parallel
sense channels. The Zennium X can control up to four PAD4 add-on cards with up
to 16 additional parallel sense channels.
Connection scheme for 4 channel PAD4 with a 5 cell battery stack. The maximum
input voltage of each PAD4 channel is limited to ±4 V with a compliance voltage
range of ±100V. The output voltage and current is limited by the electrochemical
workstation. For example the Zennium has a compliance voltage of ±14 V.

Connection scheme for 8 channel PAD4 with an external power potentiostat PP211
(20 V / 10 A) connected via EPC42 to an IM6.

The PAD4 AD converter card is also compatible with a 3rd party electronic load
interfaced from the IM6/Zennium by means of the FRA-Probe.
