Primary Data Collection Point

The OleumTech® GP-DH2-W Wireless Gateway plays an integral role in the GP Wireless Sensor  and I/O Network. It possesses the ability to aggregate data from GP wireless transmitters onto its 1920-point register holding table. Third-party devices can access the data over the Modbus or LevelMaster ASCII protocol.

Compact and Versatile

The GP-DH2-W is a full-function gateway and is ideal for fitment where enclosure space is a  premium. When it is deployed alone, it can be installed on a DIN rail having less than 1” width of space. The DH2-W can be configured as a Modbus Master or Slave device and provides Serial RS232/RS485 connectivity.

Advanced Peer-to-Peer Networking

Deploy multiple gateways to the GP platform, creating a custom, highly scalable network. The gateways have the ability to communicate with one another. Leverage the peer-to-peer technology and funnel data to the primary gateway, optimizing network efficiency and/or designing an extremely flexible I/O mapping system across the entire wireless network.

Modular Wireless I/O Expansion Solution

The GP-DH2-W can be integrated with OleumTech’s isolated Analog 0-10 Vdc, 4-20 mA, and Digital I/O Expansion Modules for solving various I/O challenges. The I/O Modules can be used in any mix or combination with the GP-DH2-W. The GP Network Configurator Software makes it extremely easy to add and configure I/O points. A standard 35 mm DIN rail is required for I/O Expansion Module(s) integration.
