{"product_id":"st4-m1","title":"ST4-M1","description":"\u003cp data-start=\"225\" data-end=\"638\"\u003eThe ST4-M1 is a 4-channel sequential timer designed for controlling loads in a fixed sequence — one after the other — with defined ON and OFF time periods for each channel. Ideal for switchgear panels, dust-collection systems, air-handling units, pneumatic conveyors and other automation applications where equipment needs to be started\/stopped in sequence without overlap. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-start=\"640\" data-end=\"658\"\u003eKey Features\u003c\/h3\u003e\n\u003cul data-start=\"659\" data-end=\"1710\"\u003e\n\u003cli data-start=\"659\" data-end=\"772\"\u003e\n\u003cp data-start=\"661\" data-end=\"772\"\u003eFour independent channels (CH1 to CH4), each with its own relay output. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003ca href=\"https:\/\/www.scribd.com\/document\/652360198\/EAPL-Connection-Diagrams-Sequential-Timers-S-Series?utm_source=chatgpt.com\" rel=\"noopener\" alt=\"https:\/\/www.scribd.com\/document\/652360198\/EAPL-Connection-Diagrams-Sequential-Timers-S-Series?utm_source=chatgpt.com\" class=\"flex h-4.5 overflow-hidden rounded-xl px-2 text-[9px] font-medium transition-colors duration-150 ease-in-out text-token-text-secondary!
