AirGate-Modbus is a wireless multifunctional gateway that allows the transparent and easy insertion of wireless branches into existing wired RS-485 networks. The AirGate-Modbus has four operation modes, Modbus Master, multiplexer, USB-RS-485 converter and simple wireless RS-485 extension. A proprietary protocol based on IEEE 802.15.4 facilitates operation in Star mode, allowing the connection of several wireless segments to an existing Modbus RS-485 network.

AirGate Modbus is a gateway specially designed to create a network of wireless sensors. It can be used as a extender of Modbus RS485 network and offers flexibility and scalability for the various networks inside facilities.

This product stands out in several aspects. One of them is the long-range wireless communication reaching up to 1000 meters (3200 feet). Operating through own NOVUS-Air wireless network protocol (802.15.4), the AirGate Modbus is independent from the IT customer infrastructure.

The communication has secure data traffic, ensured by 128-bit encryption, and uses available frequency bands of less interference, providing stability and reliability in the communication link.

Easy installation and configuration combined with diagnostics through software make the AirGate-Modbus an outstanding product for field commissioning and the ideal solution for applications requiring flexibility, high performance and connectivity.
