Ensure 24 VDC system supply power is de-energized prior to seating or removing the module.\u003c\/p\u003e\n\u003cp\u003eRoute all analog field input wiring through dedicated low-voltage wiring ductwork, physically separated from high-voltage AC cables and motor drives. Connect all signal cable drain shields to the main cabinet single-point ground bar. For conduit penetrations entering the cabinet enclosure, ensure all threaded NPT fittings achieve a minimum of 5 full threads of engagement to maintain physical strain relief and grounding integrity.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53394625364277,"sku":"P0918AH","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/FBM222P0926TL2_16d560b7-485c-4871-82be-84fb4b091d1e.png?v=1787563271","url":"https:\/\/www.5gplc.com\/products\/foxboro-p0918ah-analog-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
