Primary Data Collection Point

The OleumTech® “DH1” Wireless Gateway plays an integral role in the OTC Sensor & I/O Network by being able to wirelessly collect critical process data from OTC nodes including Wireless Transmitters, I/O Modules, and other Gateways. The data is stored in its 320-point Modbus register holding table via Serial connectivity.

Serial Interface

With the provided RS232/RS485 configurable Serial port, the DH1 can virtually interface with any third-party Modbus device either as a master or slave device. The DH1 can also be configured as a LevelMaster ASCII slave or ROC Link master. Its dedicated RS485 port (RJ-45) can be utilized for connecting to another Serial device.

Peer-to-Peer Advanced Networking

In the OTC Sensor Network, multiple Wireless Gateways can be placed into the same network to form a much larger sensor network. All Gateways can have their own set of end nodes 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.

Onboard I/O

Unlike other OTC Wireless Gateways, the DH1 is equipped with onboard I/O comprised of 4x analog inputs (0-5 Vdc), 2x discrete inputs, and 2x discrete outputs. OleumTech offers Serial I/O Expansion Modules for use with the DH1 for added functionality.
