The IL system was designed for highest demands and flexibility. Precision and reliability combined with suitability for harsh environmental conditions and easy maintainability meet the requirements of professional users from research and industry as well as demanding private users.
The modular concept allows tailor-made solutions for a wide range of applications.
An IL unit consists of the IL housing, which is suitable for outdoor use (IP54), and IL slide-in units integrated into it. IL slide-in units and IL accessories can be combined according to customer requirements.
Several IL units can be interconnected via a data bus for more complex systems.
Central control unit, shown with the following options:
Up to 3 IL slide-in units can be accommodated in one IL housing. IL slide-in units can also be used without an IL housing, e.g. in a cabinet, rack or other housing, provided that the mounting holes in the front panel of the IL slide-in units can be used for this purpose.
