Integrated electronic fusing safeguards the internal 24 VDC sourcing driver circuits against field short-circuit conditions, auto-resetting once fault parameters clear. Channel-to-backplane circuitry enforces a 50 V continuous isolation barrier, preventing high-voltage industrial field transients from interfering with host controller logic execution across ControlNet or EtherNet\/IP networks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1794-OB16P support hot-swapping or removal under power?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The module supports Removal and Insertion Under Power (RIUP) when mounted on a compatible FLEX I\/O terminal base, allowing module replacement without disrupting backplane communications or power to adjacent hardware nodes.\u003c\/p\u003e\n\u003cp\u003eQ: What happens when an electronic overload or short circuit occurs on an individual output channel?\u003c\/p\u003e\n\u003cp\u003eA: The 1794-OB16P detects the overcurrent condition and electronically trips the affected channel circuit to protect the output driver, resetting automatically once the fault is cleared and output logic cycles.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eAlign the module keying mechanism with the corresponding terminal base socket to ensure correct pin orientation before insertion.\u003c\/li\u003e\n\u003cli\u003ePress the module firmly into the terminal base unit until the side locking latches click into place.\u003c\/li\u003e\n\u003cli\u003eWire the 24 VDC field power supply and 16 sourcing output loads to the respective terminal base connections using properly sized copper conductors.\u003c\/li\u003e\n\u003cli\u003eSegregate DC output signal wiring from high-voltage AC cables in panel wireways to eliminate capacitive noise coupling.\u003c\/li\u003e\n\u003cli\u003eEnsure the terminal base assembly maintains a solid ground connection through the unpainted metal DIN rail surface.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48761494536382,"sku":"1794-OB16P","price":83.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1794-OB16P_b9a2684f-571e-4d97-8519-49e27f8d4200.png?v=1787197802","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1794-ob16p-flex-i-o-digital-sourcing-output-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
