Introduction

The ibaPADU-8-M (parallel analog & digital unit 8 multiplexed) serves as a data acqui-
sition device for applications requiring sample rates up to 25 kHz per channel. This de-
vice is suitable for vibration measurement applications, such as …



drive controller optimization



power line monitoring (with signal conditioning device)



machine vibration monitoring



rolling mill chatter monitoring



various dynamic process monitoring requiring fast signal processing

Since the majority of applications require measurements from ibaPADU-8-M devices on
a scheduled, periodic basis, devices are multiplexed. Each of up to 4 fiber-optic links
(on an ibaFOB-4i -card) may interface with individually addressed ibaPADU-8-M units.
Depending on the processing power of the PC, either 8, 16, 24 or 32 analog and binary
channels may be sampled simultaneously.

Per fiber-optic link, a maximum of 96 devices can be addressed via an ibaFOB-4i + 4o
combination or an ibaFOB-io card interface. This provides a maximum of 4x96x8 =
3072 analog and digital measurement channels.

Another possible application is the simultaneous monitoring of up to 128 analog and
128 binary channels with up to 25,000 samples / s. This operational mode is supported
by PCI cards in combination with the iba Online Data Acquisition software ibaScope
only! The master ibaFOB in that case controls the ADC converter triggering with an ac-
curacy of max. 100 ns (plus fiber optic cable length = approx. 4 ns /m) difference with-
out any jittering. This allows a variety of new applications to be performed in a wide
area with a big amount of simultaneous signals.

In order to provide a rich dynamic range each analog channel comprises a 14-bit ADC.
