Standard Design Features
Simple combustion safeguard panels built around single-purpose safety control platforms (e.g. Honeywell 7800 "Blue Box", Fireye, or Honeywell Slate) are excellent options for single burner systems or small multi-burner ovens, furnaces, and boilers that are built for "One-Button Start" operations.
Safety PLC-based systems (e.g. Compact GuardLogix, ControlLogix, ABB) are an excellent choice for larger multi-burner systems and equipment that require advanced Process Control and Safety Functions integrated into a single panel.
Our Safety PLC-based BMS platform is network-connectable with segregated process and safety IO circuits ideal for safety-integrated operation that provides local process control.
