The ELPRO 905U Wireless Multi-I/O is a node that extends communications to sensors and actuators in local, remote, or difficult to reach locations. Designed with a long range, license-free or licensed wireless transceiver, the ELPRO 905U module provides a simple to deploy solution to transfer process I/O signals reliably over long distances or within an industrial plant. Capable of transferring analog or discrete I/O points, in point to point or point to multi-point situations. Each 905U product can also provide repeater functionality to extend the distance of the network, and capture remote I/O points. I/O is scalable using 115S serial expansion units at each 905U unit.
