Main functions
Security level communication
Realize high reliability data exchange between the controller and remote I/O, upper computer, and DCS under the TMR architecture, for the transmission of alarm, process values, and diagnostic information.
Full line self diagnosis
Real time monitoring of link, channel, and protocol status, rapid fault alarm and location.
Redundant seamless switching
When the channel fails, the switching time should be less than 10ms without interrupting the safety control.
Industrial grade anti-interference
Isolation, surge protection, strong electromagnetic compatibility, suitable for harsh environments such as petrochemicals, power plants, and offshore platforms.
Typical Applications
Emergency Shutdown System (ESD)
Burner Management System (BMS)
High pressure/torch/turbine safety control
Chemical, refining, nuclear power, and long-distance pipeline safety instrument systems
