    Overview
     
    Wireless interface products provide a cost effective alternative to expensive hard wired connections. The wireless product provides continuous, 24/7 communication using the FCC licenses free 900MHz frequency. Using Frequency Hopping Spread Spectrum (FHSS) technology, a robust signal is provided that is virtually free from disruption due to interference. This technology has been proven in thousands of installations worldwide.

    Range: 600 to 1,000 feet (180 to 305 m) in-plant (obstructed);4-5 miles (6-8 km) LOS with Omni antenna; 20+miles (32+km) LOS with Yagi antenna 
    Inputs: One (1) 4-20mA analog input (16-bit, 125 ohms impedance) Two (2) digital inputs (5-30VDC) 
    Outputs: One (1) 4-20mA analog input (16-bit, short-circuit protected) Two (2) digital inputs (dry contact, NO, contact rating: 250VAC / 2 A) 
    I/O Expansion Capacity: Four (4) analog and eight (8) digital I/O modules 
    Repeatability: Current loop: 0.02% 
    Accuracy Current Loop: 0.2% of full scale at 77° F (25° C) 
    Wiring Connections: 12-24 AWG screw-type terminals; removable terminal blocks 
    Mounting: DIN-rail mount 


    Primary Power 

    Input Voltage: 9 to 30VDC 
    Reverse Polarity Protection: Yes 
    Surge Protection: Yes

    Transceiver 

    Frequency: 902 to 928 MHz -ISM band 
    Transmit Power: 1 Watt (30 dBm) 
    RX Sensitivity: -110 dBm 
    Unit ID: Factory configured (unique); 16-bit coding of each transceiver pair allows multiple units to be used in the same area 
    Antenna Connector: MCX female 
    Antenna Impedance: 50 ohms 

    Diagnostics 

    Indicators: External LEDs (power, RF link, I/O status) / RF link relay 250VAC /2 A 

    Environmental 

    Humidity:
     20% to 90% (non-condensing) 
    Temperature: Operating: -40 ° to ++158° F (-40 ° to ++70° C) 
    Size: 4.5 ” x 3.9 ” x 0.9 ” ((114 mm x 99 mm x 23 mm)
