Safety Controller

Safety controllers are typically a type of field device used to perform the safety critical function. Safety controllers often support the deployment of custom programs/logic, similar to a PLC, but can also be tailored for sector specific functions/applications. The safety controllers typically utilize redundant hardware and processors to ensure they operate reliably if a component fails.

Safety Instrumented System (SIS) controller

SIS controllers are used to "take the process to a safe state when predetermined conditions are violated" [1] through the reading of sensor data and interaction with digital/physical control surfaces. These devices are oftentimes located on programmable embedded devices running specialized RTOS or other embedded operating systems.

Emergency Shutdown Systems (ESD) controller

Emergency Shutdown System controllers are used to read sensor values and interact with control surfaces to return the system "to a safe static condition so that any remedial action can be taken". [2]

Burner Management Systems (BMS) controller

Burner Management System controllers are used to interact with sensors and control surfaces to maintain safe operating conditions for the burner. These can include safely starting-up and managing the main flame, controlling and monitoring the burning conditions, and safely initiating planned or unplanned shutdown sequences.
