Varec 8240 Tactical Data Unit

The 8240 Tactical Data Unit (TDU) collects pressure, temperature and flow measurements from connected field devices, such as the Varec 7660 Tactical Fuel Gauge (TFG) or a Tactical Flow Meter (TFM). It calculates observed fuel volumes and performs the collapsible tank mapping process. All data is transferred to the TacFuels Tactical Mobile Computer for inventory management and accounting.SpecificationsData Transmission Protocol MODBUS Pulse Accumulator Channels 2 standard, 4 optional Environmental Operating Temperature -40 to +167 °F (-40 to +75 °C) Lightning Protection Solid state transient voltage suppressors, current limiting resistors and fuses Power Supply Operating Voltage 8 – 36 VDC Power Consumption 25 mA Hazardous Area Approvals ISA/CSA Standards – Class 1 Division 2, Groups C and D ATEX and IECEx Standards – Ex II 3(1)G EX nA [ia Ga] IIB T5 Gc (-40 °C, Ta, 85 °C) Enclosure Powder coated aluminum Mounting Wall mounted/Ground rod Dimensions 10.2” x 6.3” x 3.6” (260 x 160 x 90mm) HART Output 2-position terminal, fused Pulse Input 2 channels available, 4 optional 3 to 30 VDC voltage range 30 KHz pulse frequency limit 3 position, pluggable terminal block
