MODULAR ELECTRICAL BUS SYSTEM

摘要

The invention relates to an electrical bus communication system comprising:
a main communication module; a bank of modular I/O units mounted to the side of the main communication module and adjacent each other; each modular I/O unit having an electrical fitting in proximity to each side thereof and being connected to a respective complementary electrical fitting of an adjacent module; said one modular I/O unit being removable from said bank of modular I/O units without removing said left and right modular I/O units; each modular I/O unit enclosing electronic boards therein and being distributable to a remote location and electrically connectable to the main bank and main communication module; and said main communication module constructed to automatically address each modular I/O unit with a sub-network address on either the main bank or on the remote location.
