An Industrial Timer Relay is an electrical device used to control the timing of various processes in industrial systems. It operates as a relay, but with an added feature： it includes a built-in timer that delays its switching action. The delay can be set based on the specific needs of the process, allowing for precise control over when a circuit is closed or opened. Industrial timer relays are typically used in conjunction with other control devices like programmable logic controllers (PLCs), sensors, and switches to create automated systems that require timed actions.
