If a fault occurs, the signal output drops below 3.6 mA within 100 microseconds, indicating a Not OK condition. This rapid response allows immediate corrective action. After the fault is removed, output restores within 2-3 seconds. Common issues include incorrect probe gap or loop resistance exceeding limits. Always verify the gap and loop resistance per specifications.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44416601227363,"sku":"990-05-50-02-CN","price":255.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.plcsourcepro.com\/products\/bently-nevada-990-05-50-02-cn-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
