905U-1,2,3,4 Wireless Multi-I/O Simple to deploy, long‑range, reliable wireless I/O connectivity Description 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. The I/O is scalable using 115S serial expansion units at each 905U unit. Link I/O inputs to single or multiple I/O outputs (peer to peer) Reliable point–to–multi-point two-way communications combining exception reporting, self-checking and data encryption Multi-hop repeater function provides increased communication distance Multiple I/O channels for monitoring and controlling field devices with set-point, pulse count, and rate available. Additional internal I/O points provided for health monitoring Communication failure notification and diagnostics, including radio path measurement, communications logging, and verification of I/O values Built-in low voltage AC/DC/battery power options, UPS battery charger and solar regulator User-friendly configuration software Flow meter monitoring Storage tank monitoring Pipeline cathodic protection Pump stop-start Weather station reporting High‑level alarms
