{"product_id":"allen-bradley-849-zab33-pneumatic-timing-relay","title":"Allen-Bradley 849-ZAB33 Pneumatic Timing Relay","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 849-ZAB33 Pneumatic Timing Relay is a legacy Allen‑Bradley timing device that delivers controlled time delays in industrial control circuits using a pneumatic bellows mechanism. Belonging to the 849 family, it functions as a timing relay with a pneumatic timing element driven by compressed air, avoiding electronic timing components in the timing loop; the 849 suite uses synthetic rubber bellows to set and reset timing actions. The ZAB33 designation identifies a specific variant in the catalog, part of a family that includes several enclosure\/variant endings (32 and 33 being common suffixes). This model is widely listed as discontinued by major distributors, so available stock is typically limited to surplus or secondary-market sources. Applications include sequencing, interlocks, and safety routines in manufacturing lines where a purely pneumatic timing solution is preferred for reliability or isolation from electrical noise, and it typically partners with standard relays and contactors to implement time-based control without electronics in the timing path.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657428828462,"sku":null,"price":174.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d492e809-deaa-4b14-a618-0e037c5269cd.jpg?v=1769468866","url":"https:\/\/plgautomation.com\/products\/allen-bradley-849-zab33-pneumatic-timing-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
