Compact measurement modules

Acquire signals with high precision on site

Using the ibaPADU (Parallel Analog Digital Unit) device family, analog and digital signals can be acquired and recorded with high precision by the data acquisition system ibaPDA. Fast and synchronous sampling of all signals allows detailed analyzing of all processes.

Compact Measurement Modules at a Glance



  • Sampling rates from 1 kHz to 100 kHz, depending on the device
  • Simultaneous data acquisition due to one A/D converter per channel, 16 bit resolution
  • Adjustable level and input characteristics
  • Each channel galvanically isolated
  • Integrated filters reduce disturbances

Product Highlights

Anti-aliasing filters reduce disturbances

A digital filter can be activated per channel together with an analog anti-aliasing filter. The digital anti-aliasing filter is adjusted automatically to the configured sampling rate.

Comfortable configuration in ibaPDA

The signals are converted internally and are available via the FO interface. The signals can be conveniently selected and configured with ibaPDA. All necessary parameters like input signal range, input impedance, or filters can be adjusted for each channel in the software.

Inputs for current and voltage signals

ibaPADU is a device family for measurement of analog and digital signals. The analog inputs are available as current and voltage inputs with different measuring ranges. Each channel is galvanically isolated and equipped with its own A/D converter.

Additional Connection

Each device has an additional 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.

Analog low-pass filter

An analog low-pass filter is permanently active in both devices ibaPADU-8AI-U and ibaPADU-8AI-I. In the voltage module ibaPADU-8AI-U, an additional digital low-pass filter can be activated as option.

With the 3Mbit protocol up to 1 kHz

The devices ibaPADU-8AI-U and ibaPADU-8AI-I work with the 3Mbit protocol. Thus, up to 8 devices can be linked in a daisy-chain on the fiber optics link and up to 64 analog and 64 digital signals can be transmitted at a fixed sampling rate of 1 Hz. The possible distance between two devices may be up to 2 km.

Flexible settings with "Flex" protocol

The devices ibaPADU-4-AI-U, ibaPADU-D-8AI-U and ibaPADU-D-8AI-I work with the 32Mbit Flex protocol. With 32Mbit Flex, the data transmission rate is 32Mbit/s and up to 15 "Flex" devices can be connected to a ring topology.

Different device modes

which provide the device specific properties of the previous devices like measuring range, input impedance and filters, are set by means of a rotary switch.
