Its wide operating temperature range (-40 to +70 deg C) allows for placement in unheated field enclosures, reducing infrastructure costs. Furthermore, the Series 2 HART integration provides a \"future-proof\" foundation for IIoT initiatives, allowing users to unlock stranded diagnostic data from field assets without adding secondary multiplexing hardware. The high-density design and 11 ms shock resistance (10 g) make it ideal for compact cabinets located near heavy rotating machinery.\u003c\/p\u003e\n\u003ch3\u003e\u003c\/h3\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":52695422927211,"sku":"KJ3222X1-BA1 12P2532X072  VE4033S2B1","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/EmersonKJ3222X1-BA112P2532X072VE4033S2B1.png?v=1775914980","url":"https:\/\/www.plcprotech.com\/fr\/products\/kj3222x1-ba1-ve4033s2b1-emerson-deltav-ai-8-ch-hart-redundant-system","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
