905U-G Range Wireless Gateway

Key Features:

ELPRO wireless gateways designed to provide the interface and communication between industrial data-bus devices and field devices Connected via RS-232/RS-485/RJ-45, register-allocated data-bus values are transmitted and received by radio.In addition ELPRO 905U-G series products can multi-hop repeat up to four times in addition it is considered and ideal solution in creating powerful I/O and data bus networks as it support a variety of industrial protocols .
• 865–867 MHz/902–928 MHz 1W, 19.2 kbps radio communications to 20 miles (32 km)
•Multi-hop repeater function provides increased communication distance
•Able to connect similar and dissimilar industrial protocols and vendor devices (incorporating master/slave, slave/slave, and master/master networks)
•Simple to complex networks, high reliability point-to-multipoint communications with forward error correction (FEC), data integrity check (CRC), and data encryption
•Eight configurable digital onborad I/O with I/O expansion via ELPRO 115S I/O expansion range
• AC/DC/battery power options with UPS battery charger
• Module diagnostics including read/write of register I/O, reporting of signal strength indication (RSSI), communications logging, and internal measurement of low/normal and battery supply voltages
•Class I Div 2 hazardous area approval (US/Canada)
