Simple-to-deploy, long-range, reliable wireless I/O connectivity

The ELPRO 105U Wireless Multi-I/O is a multiple I/O 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 105U 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 105U product can also provide repeater functionality to extend the distance of the network and capture remote I/O points. The I/O is scalable using 115S serial expansion units at each 105U unit.
