Ensure the backplane lock engages securely to maintain electrical connection and ground continuity. Connect 4-20 mA signal wiring using recommended twisted shielded pairs, terminating the shield line at a single grounding point on the functional earth rail to preserve channel isolation and EMC performance. Verify ATEX\/IEC explosion protection requirements prior to applying field power in hazardous locations.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48540009791678,"sku":"ASI133-H00","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-08-06_11-17-10_bbf58d74-2b47-4f41-8fa3-83f6a48646a9.png?v=1785986406","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-asi133-h00-analog-input-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
