Sequence Controller
Sequence Controller
A Sequence Controller is an essential component in burner management and automation systems, designed to ensure the safe, reliable, and sequential operation of industrial burners and heating equipment. It orchestrates the step-by-step process of ignition, combustion, monitoring, and shutdown, making sure each stage follows a precise, pre-programmed logic. Sequence controllers are crucial for maintaining safety, maximizing efficiency, and preventing malfunction or hazardous conditions during burner operation.
Used extensively in boilers, furnaces, ovens, and incinerators, sequence controllers monitor and control critical parameters such as flame presence, air pressure, fuel supply, pre-purge timing, ignition, and flame failure response. These devices are available in both analog and advanced microprocessor-based digital models, offering programmable functionality and interface options for a wide range of industrial applications.
