It operates by switching its output when the sensed pressure crosses a user-set point, making it suitable for protecting and automating compressors, pumps, hydraulic systems, and related fluid circuits. The 836-A1A uses Style A architecture and offers an adjustable operating range from 30 inHg vacuum up to 375 psi, with an adjustable differential from about 2 to 95 psi, and supports maximum line pressures up to 750 psi with occasional surge ratings up to 850 psi. The unit’s control circuitry is rated up to 125 VA and supports a control-voltage range from 24 to 600 V, enabling integration with a wide range of control circuits and relays. In addition to its rugged metal enclosure and mechanical reliability, this 836 family switch is designed for dependable operation in varied industrial environments where precise, repeatable pressure switching is essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657436234030,"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_42e0752d-2536-4500-9a28-1fef68a077a3.jpg?v=1769468948","url":"https:\/\/plgautomation.com\/products\/allen-bradley-836-a1a-pressure-control-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
