The DN300-SA-4G is an 8 channel telemetry unit that can be used for monitoring and control functions. The unit has a 4G modem module that can be changed to a WiFi module (where there is a local area WiFi network available) or satellite.
The standalone (4G) option is generally used where only a few sites are required, and where a gateway and radio network isn’t cost effective. It is very easy to upgrade a DN300-SA-4G unit to a gateway, if additional sites are required at a later date. All that is required is a plug in radio module and an additional antenna. The DN300 can be remotely configured to upgrade from a standalone to gateway unit.
An additional 3 8 channel expansion boards can be connected to provide 32 inputs and/or outputs.
