MAXIO™ distributed I/O modules can significantly reduce system costs by eliminating long runs of field wiring, reducing the size of electrical panels, reducing startup and maintenance time.

MAXIO™ support RS-485 links up to 1 mile over low-cost twisted pair wiring, and RS-232 links for local connections to PC computers and equipment, as well as modem interfaces to data radios, leased telephone lines or fiber optic cable. A single network over any media is expandable to 8,000 I/O points.
