The A723 Series 4 Radio Telemetry Unit (RTU) can accept up to 48 inputs, 2 digital output and power to attached sensors vis analog or SDI-12 interfaces. While from the outside nothing appears to have changed on the inside of the fourth edition of the A723 addIT telemetry unit nothing has remained the same! There are many new and improved features.
The low power consumption of the A723 addIT Series 4 Radio Telemetry Unit means that it can be powered by a standard solar panel. With an integrated 10mW radio module, it is an extremely versatile RTU. It is also a 50 channel data logger with easily customisable transmission and measurement intervals. It can acquire and transmit both digital SDI12 and analog sensor values, digital status signals and meter pulses over distances up to 1km.
Installation in the field is very straightforward. With all of the components integrated into a single telemetry system housing it's as easy as fixing the housing to a pole, plugging in your sensors and connecting to the postcard sized solar panel. The robust aluminium housing (IP-66) ensures operation all year round, even in the harsh environments.
The A723 addIT series 4 telemetry device is fully compatible with the A840 and A850 telemetry gateways. However, you may have to upgrade your gateway to make use of some of the new features. It is also fully compatible with all current long range devices such as the A740 addNODE, A733 addWAVE and A731 addRELAY. It is not compatible with the A720, A730MD and A730SD.
