Description

The DH3 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, I/O modules, and other gateways onto its 1920-point register holding table. Third-party devices can access the data over the Modbus or Level Master ASCII.

The 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 the DH3’s secure web server.

Multiple gateways can be deployed to the OTC platform for creating a custom, highly scalable network. The gateways have the power to communicate with each other. You can leverage the peer-to-peer technology for funneling data to the primary gateway for optimizing network efficiency and/or designing an extremely flexible I/O mapping system across the entire wireless network.

Equipped with both Ethernet and Serial ports, the DH3 is designed for interfacing multiple third-party devices. Having both Modbus Master and Slave functionalities, the DH3 provides endless possibilities for solving telemetry challenges. We offers a local I/O expansion solution for integrating analog and discrete I/O capabilities to the DH3. An optional touchscreen LCD display is also available for added convenience.
