Customer feedback has triggered the development of the A731 addRELAY. In difficult terrains or to bridge large distances the A731 is an attractive alternative.
If installed well, ideally in an elevated position like on top of an antenna tower, e.g. of a GSM base station, or on the roof of a storage silo, an A731 addRELAY can achieve distances going even beyond the 20km limit. With more than 10 RTU's to be routed through one A731 addRELAY we recommend the usage of a mains adapter.
Installation is rather easy. With all major components - CPU, radio and battery - packed into a single, compact aluminum case the A731 addRELAY only needs to be fixed to the mast. Connecting the solar panel will activate the RTU. No separate external enclosures are required.
