After power initialization, the module establishes communication links with upper main controller and lower field devices. It receives data frames from each node, completes protocol parsing, conversion and re-encapsulation, then forwards data to target equipment. The isolation and protection circuits filter surge and interference signals on transmission lines to ensure continuous and error-free data transmission.
- Rich interface configuration, meeting diverse system expansion requirements
- High isolation and lightning protection capability, adapting to long-distance field wiring
- Stable high-speed transmission, supporting large-volume real-time data interaction
- Redundant link support, improving overall system operation reliability
- Compact structure, saving rack installation space for centralized layout
Large-scale power plants, coal chemical industry, oil refineries, municipal energy systems, remote monitoring and control projects
- Install in the specified slot of Ovation DCS main control rack and lock firmly
- Use original shielded communication cables for external connection
- Follow DCS standard specifications to complete shielding layer grounding
- Keep away from high-power frequency converters and motors to reduce electromagnetic interference
