It operates from a 220-240 V AC coil and is suitable for 50\/60 Hz operation, with a NEMA 1 enclosure designed for indoor, general-purpose installations. This 849-series relay uses a pneumatic timing mechanism—typically based on a bellows design—to deliver a defined delay before energizing or de-energizing a downstream actuator, making it well-suited for valve actuation, cylinder sequencing, and other timed control applications in automated systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657428893998,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_469fc9ef-3067-48ad-bf2f-2bd2621622d6.jpg?v=1769468867","url":"https:\/\/plgautomation.com\/products\/allen-bradley-849-zaa321-pneumatic-timing-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
