Primary Data Collection Point

The OleumTech® DH2-W Wireless Gateway plays an integral role in the OTC Wireless Sensor and I/O Network. It possesses the ability to aggregate data from OTC wireless transmitters and I/O modules 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 DH2-W is a full-function Gateway and is ideal for fitment where enclosure space is a premium. When it is deployed by itself, it can be installed on a DIN rail having less than 1-inch width of space. The DH2-W can be configured as a Modbus master or slave device and provides RS232/RS485 connectivity.

Peer-to-Peer Advanced Networking

Deploy multiple gateways to the OTC 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

OleumTech offers isolated 0-10 Vdc, 4-20 mA, and Digital I/O Expansion Modules for use with the DH2-W for solving various I/O challenges. The I/O Modules can be used in any mix or combination with the DH2-W. The BreeZ® 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.
