The use on ships and in the offshore sector places very special demands on the products used. In this environment, resistance to salty air must often be precisely defined. Opto-decoupled RS-422 interfaces are also often required.
The frequency ranges that can be used on ships in particular are precisely regulated. IPCs should be designed to withstand electromagnetic interference that can be caused on ships by electrical equipment and navigation systems.
IPCs should have the necessary maritime certifications, such as DNV GL (Det Norske Veritas Germanischer Lloyd), ABS (American Bureau of Shipping) or others, depending on the region and requirements.
