Configured for direct mounting on standard DIN rails or baseplate panel assemblies, it provides direct physical execution of primary and secondary field I\/O bus coupling. The unit manages 4-20 mA analog loops alongside TTL\/CMOS digital signals, executing hardware failover mechanisms upon detection of primary bus faults.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eP0916NN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFoxboro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.54 kg (1.19 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e147 x 51.5 x 114 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;= 8.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e100-120 VAC (redundancy cfg) \/ 24 VDC (control cfg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e5-30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Switching Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Types\u003c\/td\u003e\n\u003ctd\u003e4-20 mA Analog, TTL\/CMOS Digital\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Response Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 50 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDCS Bus Redundancy and Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-availability Foxboro I\/A Series architectures, the P0916NN adapter coordinates dual Fieldbus channels to guarantee uninterrupted 4-20 mA HART loop protocol and discrete telemetry passthrough. Integrated hardware logic executes automated failover with redundancy switching times under 10 ms during primary trunk or power feed interruption. High-density channel-to-channel isolation prevents field wiring transients from transferring between active and backup Field Bus Modules (FBM205\/FBM208), maintaining signal integrity across process control loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the P0916NN support hot-swapping during active DCS operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module features hot-swappable hardware architecture. An adapter or associated Field Bus Module can be removed or replaced under 24 VDC backplane power without interrupting communications on the parallel redundant bus.\u003c\/p\u003e\n\u003cp\u003eQ: How does the P0916NN handle signal switching delays during a bus failover event?\u003c\/p\u003e\n\u003cp\u003eA: Internal hardware monitoring triggers bus switchover in less than 10 ms, ensuring that 4-20 mA control loops and digital status scans remain continuous without triggering DCS system alarm trips.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the P0916NN module onto a standard 35 mm DIN rail or secure it to the panel baseplate using designated mounting screws.\u003c\/li\u003e\n\u003cli\u003eSeat the module firmly into the FBM205\/208 redundant baseplate interface, ensuring all backplane connector pins line up before fully latching.\u003c\/li\u003e\n\u003cli\u003eWire the dual 24 VDC power feeds and 4-20 mA field loops into the labeled screw terminal connectors, observing correct polarity alignment.\u003c\/li\u003e\n\u003cli\u003eVerify that the cable shield drain wire connects directly to the system grounding bar to maintain electromagnetic isolation across field signal lines.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53406154555701,"sku":"FBM205\/208 P0916NN","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/P0916NN.png?v=1787724182","url":"https:\/\/www.5gplc.com\/products\/foxboro-p0916nn-fbm205-208-i-o-redundancy-adapter-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
