A440 Wireless Modem
A440 Wireless Modem
DISCONTINUED
- Wireless modem
- IP-67; 20km range and even beyond depending on installation
- Radio communication (430-470MHz), 500mW
To communicate with ADCON's UHF RTUs the A440 employs the same 500mW radio modem as is also being used in our long range units A731, A732 and A733. By default the A440 is meant to be mounted in an elevated location, for example on the roof of the building where the A850 is installed.
With proper installation distances of up to 20km can be achieved. Please make sure that installation is done with proper grounding of both components, A850 and A440. Consult an expert technician to make sure that all guidelines and recommendations for lightning protection are observed!
A440 is available in four different frequency bands, each covering 10MHz. Please make sure to order the correct frequency range according to your local regulations.
