Primary Data Collection Point

The OleumTech® GP-DH3 Wireless Gateway plays an integral role in the GP Sensor and I/O Network by being able to wirelessly collect critical process data from GP transmitters and other gateways in the network. The collected data is stored in its 1920-point Modbus register holding table.

Data Logging Capabilities

The GP-DH3 offers both event-based data logging and time-based trending/logging capabilities. The data can be stored onto its internal RAM (volatile) or onto an optional industrial-grade Micro SD card (non-volatile). Trend graphs are accessible via GP-DH3’s web server.

Advanced Peer-to-Peer Networking

In the GP Network, multiple wireless gateways can be deployed to the same network to form a much larger sensor network. All gateways can have their own set of transmitters and they have the ability to communicate with other gateways in the network. With this powerful advantage, you can setup sophisticated I/O distribution systems and migrate data with extreme flexibility, scalability, and ease.

Ethernet + Serial + Local Display Option

Equipped with an Ethernet and two configurable Serial ports, the GP-DH3 can interface third-party Modbus devices as a Master and/or Slave for delivering data to the cloud. OleumTech offers Serial I/O Expansion Modules for use with the GP-DH3 for added functionality. An optional touchscreen LCD display is available to instantly view process data and access device settings. The local display requires zero configuration.
