RPU - Repeater Unit

RPU001The SPS ( Repeater Unit) is designed to increase the range and coverage area of the LAN.
The SPS acts as an RF transceiver between BSU (Base Station) and ( the ) module ( s ) radio RTU.
The SPS receives and transmits information between the radio modules RTU and BSU.
The SPS repeater can be equipped with a solar panel and rechargeable backup batteries or may have an external power supply.
Up to three can be installed SPS chain ( hopping ) between ( the ) RTU and BSU .
