The modules ibaMS3xAI-1A, ibaMS3x-AI-5A and ibaMS3x-AI-1A/100A are part of the iba modular system. The design and the operation of all modules are similar, they only differ in technical specifications (signal level). The description is based on the example of the ibaMS3x-AI-1A/100A module.

The modular concept of the iba modular system is based on a module rack with backplane bus, onto which a central unit and up to 4 additional input or output modules can be plugged. The module is supplied with power via the backplane bus in the module rack.
