Output scaling is executed in fixed conversion intervals of 512 microseconds. Signal integrity is dependent on shielded field wiring and single-point ground termination due to absence of per-channel isolation. External 24 VDC supply supports field-side output driver stages independent of logic backplane rail.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1746-NO4V support individual channel isolation?\u003cbr\u003eA: No. All four outputs share a common non-isolated architecture referenced to module common.\u003c\/p\u003e\n\u003cp\u003eQ: Can the module be removed under live backplane operation?\u003cbr\u003eA: The module does not support hot-swap. Removal requires SLC 500 rack power shutdown to avoid backplane disturbance.\u003c\/p\u003e\n\u003cp\u003eQ: What is the effect of external 24 VDC supply loss?\u003cbr\u003eA: Loss of external 24 VDC disables field output drive stages while backplane logic remains powered, resulting in zero output state.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eInstall module into SLC 500 chassis slot with full backplane connector engagement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure rack power is isolated before insertion or removal.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUse shielded cable (e.g., Belden #8761) for all analog output channels.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTerminate cable shields at a single earth reference point only.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaintain separation between analog output wiring and high-frequency switching conductors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVerify terminal block locking before energizing system power rails.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43505369710682,"sku":"1746-NO4V","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1746-NIO412.jpg?v=1781606221","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1746-no4v-slc-500-analog-output-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
