ECM/C3 Communication Module

Feature & Principle

It is Triconex ECM/C3 enhanced communication module applied in Tricon triple modular redundant safety instrumented system. It undertakes communication offloading task of main processor, realizes data interaction between safety controller and upper DCS, HMI and Modbus field devices. It has built-in electrical isolation to avoid external signal interference damaging the safety rack. It supports online hot replacement without system shutdown, with built-in communication diagnosis function to capture link fault in real time. Widely used in petrochemical, oil & gas ESD and burner management cabinet.
