The module transfers output commands from the central processor across the FlexBus backplane to switch 24 VDC sourced power to connected field devices. Solid-state switching electronics provide galvanic isolation between logic-side microcircuitry and field-side actuator power distribution loops.\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\u003eTC-FOD161\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\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\u003e0.22 kg (0.49 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard FlexBus module footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e0.3 W (Backplane) \/ External Field Load Dependent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Power\u003c\/td\u003e\n\u003ctd\u003e5 VDC at 60 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eSourcing Discrete Output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Interface\u003c\/td\u003e\n\u003ctd\u003eFlexBus Backplane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation \u0026amp; Discrete Load Management\u003c\/h3\u003e\n\u003cp\u003eThe Honeywell TC-FOD161 incorporates channel-to-channel isolation and galvanic protection to shield internal backplane logic from field voltage transients and inductive kickback caused by switching solenoids or relay coils. Operating on 24 VDC sourcing outputs, each channel routes current directly from the external 24 VDC field power bus to the field load. The hardware layout maintains separation between low-voltage 5 VDC backplane control logic drawing 60 mA and high-current field output circuits, eliminating common-mode ground noise across the DCS network.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the backplane power draw for the TC-FOD161 from the FlexBus rack?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 60 mA at 5 VDC from the FlexBus backplane for internal logic operations, while field-side load current is supplied independently through the external 24 VDC power bus.\u003c\/p\u003e\n\u003cp\u003eQ: Does the TC-FOD161 provide current sourcing or sinking outputs to field devices?\u003c\/p\u003e\n\u003cp\u003eA: The module operates strictly as a sourcing output device, switching the positive terminal of the 24 VDC field power supply to connected load terminals.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module handle back-EMF spikes generated by inductive field loads?\u003c\/p\u003e\n\u003cp\u003eA: Internal suppressors and galvanic isolation networks attenuate voltage transients from inductive loads like solenoids or contactor coils before they propagate to the FlexBus backplane.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower down the FlexBus rack and disconnect the external 24 VDC field supply prior to installing or removing the module.\u003c\/li\u003e\n\u003cli\u003eAlign the TC-FOD161 card with the rack guides and press firmly until the rear connector fully seats into the FlexBus backplane.\u003c\/li\u003e\n\u003cli\u003eWire the external 24 VDC field power supply to the designated power terminals, ensuring correct polarity for sourcing outputs.\u003c\/li\u003e\n\u003cli\u003eRoute discrete output wiring through cable channels separate from high-voltage AC mains and sensitive analog input lines.\u003c\/li\u003e\n\u003cli\u003eGround the mounting rack and enclosure to the single-point facility earth ground bus to preserve system noise immunity.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52368593846568,"sku":"TC-FOD161","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/TC-FOD161.png?v=1789113955","url":"https:\/\/www.powerdcs.com\/es\/products\/tc-fod161-honeywell-flexbus-digital-output-module","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
