Design and safety considerations of I/O modules

In Magnetic Particle Imaging, numerous data inputs and outputs are required to receive and process signals from the feedback and receive coils, and to control the output associated with the drive and selection field coils. Previously used conventional input/output (I/O) boards have shown limitations in regard to the initial start-up
procedures, safety assurance and usability. In order to address these issues, a more sophisticated I=O-Unit was designed, incorporating and expanding the functionality of twelve measurement cards. These cards are housed within the I=O-Unit as shielded, interchangeable modules and built up as synchronised multi channel I/O system.
