905U-K Wireless IO Module

The ELPRO 905U-K Wireless I/O is a small I/O transmitter that extends long range, license-free communications to sensors in local, remote, or difficult to reach locations. Designed with low power consumption and simple plug-in of ELPRO BU-5 Battery Packs, the ELPRO 905U-K provides reliable continuity in environments typical of industrial applications with power constraints. Capable of transferring analog, pluse or discrete inputs, and powering a loop powered analog device (24Vdc, 50mA), offers a simple to deploy and highly reliable solution.
