The DH2 Wireless Gateway or Wireless Base Radio is the central data collection point in the Edac Wireless Sensor Network for monitoring critical process conditions designed especially for the remote field applications.
The DH2 is responsible for receiving/collecting data from wireless end nodes such as Edac Wireless Transmitters, Wireless I/O Modules, and other Wireless Gateways. The collected data can be communicated with third-party Modbus device such as a RTU, PLC, EFM, HMI, or DCS via RS232 or RS485 Serial port.
The DH2 is unique from other base radios in the marketplace because it can also be utilized for creating a peer-to-peer network infrastructure. By combining multiple gateways in a same network, data can be shared amongst them. Thus, a user can stretch a network over many miles using Gateways as repeaters or create a robust, sophisticated network by sharing data across multiple Gateways with its own group of end nodes.
The DH2 is an ideal replacement for a hardwired/wired system for enabling wireless emergency shutdown (ESD), wireless valve control, and many other mission-critical applications.
Edac offers another Gateway: the Base Unit with onboard I/O for additional flexibility and control.
The DH2 is certified for Class I, Division 2 hazardous location use.
