It has high availability of operation at extended operating temperature and can be mounted on a DIN rail with external magnetic antennas.
Endowed with high connectivity and connection redundancy, it has cellular network (dual simcard), Ethernet, Wi-Fi, RS485 and RS232 interfaces. With excellent flexibility, it can operate with any communication protocol on any interface.

Monitor levels and alarms over a 4G phone network. The AirGate-4G is a 4G cellular router for Internet of Things (IoT) applications and provides remote access to local networks. It acts as a Modbus RTU master and reads coils and registers of Modbus remote channels. Using the Modbus connection you can connect Analog and Digital I/O modules and counters to the airgate and monitor and control them over a 4G Telstra, Optus or Vodafone network. SMS alarm messages can be generated on alarm situations. To make life easier for you all data generated can be published on NOVUS Cloud platform, which allows access anytime and anywhere, besides providing efficient and reliable storage.

Ready-to-use in cloud platforms, it provides secure MQTT data communication to enable sending data from legacy industrial networked devices to cloud systems.
