505U-K Wireless I/O One‑way low‑power transmitter Description The ELPRO 505U-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 505U-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 (24 Vdc, 50 mA), the ELPRO 505U-K offers a simple‑to‑deploy and highly reliable solution. 869.525 MHz frequency and 500 mW RF power, or 869.875 MHz frequency and 5 mW RF power models Link process inputs to single or multiple outputs (peer to peer) Multiple power supply options, including battery-only supply with ultra-low power consumption (reverts to “sleep” mode) Input-only transmitter unit (2 or 4 DI/PI, 1 AI) that can be connected to multi‑I/O and/or gateway units, up to 3000 units in a system Peer-to-peer communications with exception reporting, reliable self-checking via update time, and secure data encryption External inputs plus internally calculated values, including analog set point status, pulse rate and pulse total, power/battery supply voltage, and power supply alarm Can connect to up/down counter transducers, such as shaft encoders Configurable repeat transmissions to five times for message reliability Set point, pulse count, and rate available. Additional internal I/O points provided for health monitoring Security gate control Emergency shower notification Flow meter monitoring Storage tank monitoring Pipeline cathodic protection Pump stop-start Lighting bank control Power reticulation relay fault notifications Weather station reporting
