Reliable Burner Management and Fired Equipment Protection:
Diamond-SIS® is a cyberproof, safety-certified single-loop controller, also commonly called a safety trip amplifier or analog safety relay. Installed near the fired equipment, Diamond-SIS® can provide the sequencing and protective functions needed for safe startup, operation, and shutdown.
Integrated Diamond-SIS® systems can execute burner management functions including timed purge and light-off sequences, fuel pressure monitoring, flame detection, pass flow, drum level, and firebox pressure. Dedicated loops monitor critical process conditions and take action when needed, providing highly reliable protection without the complexity of a PLC-based system.
Diamond-SIS® provides a practical, cost-effective solution for burner management systems, fired equipment interlocks, low-integrity protection layers, and safety instrumented systems (SIS).
