The A723 addIT is a versatile RTU (Remote Telemetry Unit) with an integrated 10 mW radio module. Its extremely low energy consumption allows for permanent solar powered operation.
Technical Specifications
The A723 addIT features 10 I/O's and can acquire and reliably transmit analogue sensor values, meter pulses, or digital status reports over distances up to 1.000 meters. Measurement and transmission intervals can easily be adjusted.
A robust IP-67 housing ensures year-round operation even in harsh environments. A723 is fully compatible to Adcon's long distance transmission units A731 addRELAY, A733 addWAVE and A740 addNODE and can thus easily be integrated into existing networks.
Just like it's bigger brothers from the current A73x series the A723 addIT contains all major components - data logger, radio, power supply - in a single, compact aluminum enclosure, thus making separate external enclosures obsolete. Installation in the field becomes a very straightforward procedure - fix it to the pole, connect the solar cell and the sensors - done!
Applications
The A723 addIT is particularly popular in agriculture. Optimizing irrigation systems requires the installation of soil moisture sensors in large numbers within limited areas. With up to 6 soil moisture sensors attached to only one addIT vital data can thus inexpensively be relayed back to base through an existing network of Adcon weather stations.
The optional A506 SDI-12 Adaptor makes the A723 addIT even more competitive. Up to 20 additional sensors can be attached via an SDI-12 connection (provided they either have a very low power consumption or bring their own battery pack). Imagine this to be 5 multi-level soil moisture probes, featuring four sensors each, or a big multi-parameter probe for water quality monitoring, which outputs anything from temperature, level, and pH to EC, turbidity and VOC's.
