Enclosure for Central Site RME111

Vaisala Radio Modem Enclosure for Central Site RME111 is used for enabling and combining weather sensor data radio communication between field sensor sites and central site.

RME111 is a connection box that provides options, radiation shield protects the enclosure, mounting, powering, backup enclosure from excessive solar radiation, battery, surge protection, and needed and cable cover protects cable internal cabling for radio modem units, throughputs in outdoor environment. and also for radio combiners, Mast options include mounting support when needed. for 63mm, 75mm, 102mm, 106mm pole masts, and mounting support for DKP11 Radio Modem Housing and DKE200 lattice masts. DKP711 Capacity frangible 1.2m fiberglass mast and RME111 can contain up to 8 radio modem DKP721 frangible 2.0m fiberglass mast Features units and 2 radio antenna combiners, as can also be bought with RME111. standard. The number of radio modem • Room for 8 radio modem units interfaces can be flexibly selected Safety Features Included and 2 combiners as standard between 1 and 8 to meet the needs in a RME111 includes separate surge • Robust and tight (IP66) stainless cost effective way. Vaisala has designed protection for input electricity, input steel housing protecting sensitive the RME111 unit for certain selected and antenna cable, and output serial data equipment field proven radio modem models. cable (RS485 / RS232). These surge • Separate surge protection for each Compatibility with other radio modem arrestors are protecting the radio antenna cable, data output cable, models should be verified separately. modem units and power supply from and power input RME111 can house also up to 2 radio damages caused by lightning activity • Recharging backup battery for antenna combiners. One radio antenna and bad or varying electricity quality. continuous operations through combiner can be used to combine 2-4 RME111 includes also recharging backup short power outages radio modem units to use only single battery for continuous operations receiving end radio antenna instead of through short power outages. The multiple antennas. By using combiners battery provides backup power for at the amount of radio antennas installed at least 6 hours for 2 and for at least central site can be decreased, and excess 2 hours for 8 radios. antennas in the radio mast can be avoided. RME111 can also be used without Radios, Combiners, and combiners, but this is recommended Antennas only, when only few radio modem units RME111 itself does not include fixed radio are needed. modem units, radio antenna combiners, RME111 includes also 10m antenna signal or radio antennas, because these cables, as standard, for the needed radio components are frequency dependent. antennas. This choice has been made to increase flexibility of RME111, because these Installation Options frequency dependent components can RME111 can be installed indoors or vary between different customer, outdoors, and to wall or mast. Indoor country, or project specific needs. wall installation is the most commonly Needed frequency dependent needed option and there only the IP66 components are included in the Vaisala stainless steel enclosure is needed. In Radio, Combiner, and Antenna Set outdoor wall or mast installations also RCA111, or as separately selected items. mounting frame, radiation shield, and The radio , combiners, and cable cover are needed. Mounting frame antennas will be fully installed and enables different mast installation integrated to RME111, so the end result is fully working and tested radio communication system for central site.
