System power su

pply and redundancy: Provide 24V redundant power distribution for the FSC system to ensure stable power supply for controllers and I/O modules, and support seamless fault switching.
Safety control processing: Integrate safety logic circuits to participate in critical safety functions such as safety interlock, emergency stop (ESD), and combustion control.
Signal isolation and conversion: Isolate on-site 24V signals, adapt to the FSC system’s voltage standard, resist electromagnetic interference, and enhance system stability.
Status monitoring and diagnosis: Built-in power, temperature, and fault monitoring circuits can upload diagnostic information to the system, facilitating maintenance. Typical application
Safety Instrumented System (SIS): Emergency shutdown, burner management, process safety interlocks for chemical, petrochemical, and natural gas facilities.
Power plants / power stations: Safety monitoring for boilers and steam turbines, auxiliary control for excitation systems.
Industrial redundant control systems: 24V power supply and safety processing scenarios requiring high reliability.
