Sequencers are not a specific brand but a category of industrial control devices used to automate processes in manufacturing, power generation, and other industries. They are typically produced by various companies worldwide, such as Allen-Bradley (USA, owned by Rockwell Automation), Siemens (Germany), and Omron (Japan). Sequencers manage the order of operations in machinery, ensuring tasks are performed in a predefined sequence. Common products include programmable logic controllers (PLCs), timer relays, and step sequencers, which are widely used in assembly lines, HVAC systems, and electrical panels. These devices enhance efficiency and safety in industrial automation.
