Modular concept

The I/O module described in this documentation is part of the ibaMAQS modular measurement system.

The modular system consists of a central unit (ibaM-DAQ processor module or the ibaM-COM communication module), which can be combined with up to 15 different I/O modules. Modules are available for discrete input and output signals as well as for special technological features.

The I/O modules do not require their own power supply since they are powered via the module-module interface. The operating status of the module as well as the status of the individual channels are indicated by LEDs.
ibaM-4AI-IEPE

The ibaM-4AI-IEPE module is designed for the acquisition of mechanical vibrations with IEPE vibration sensors. Different input modes can be set in ibaPDA for each channel for the analog inputs:

  • IEPE input with 1 Hz or 0.1 Hz high-pass filter

  • 24 V AC input

  • 24 V DC input

Overview of the most important features:

  • Input module with 4 analog inputs

  • Constant current source 4 mA for sensors

  • Typical for IEPE sensors

  • Detection of broken line and short circuit

  • Galvanically isolated analog inputs

  • 24 bit resolution

  • Sampling rate A/D converter 100 kHz

  • Timebase 10 µs to 1 ms, freely adjustable

  • Analog and digital filters per channel

  • Rugged housing, easy installation

The maximum number of ibaM-4AI-IEPE modules on a processor or communication module is not limited. A maximum of 15 of these modules can be operated on one of the two central units.
