{"product_id":"qbp767996","title":"Simrad NAC-2 Low Current Autopilot Computer, For Boats Up to 10m, 9-31.2V, 8A Continuous\/16A Peak, NMEA 2000, Virtual Rudder Feedback, IPX5","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Simrad 000-13249-001 is a NAC-2 low-current autopilot course computer that runs the steering drive and ties the rest of the pilot system together over NMEA 2000. It supports 9 to 31.2 V DC power (12 V and 24 V systems) and is intended for boats up to 10 m (33 ft), where an 8 A continuous drive output matches typical low-current pumps, mechanical drive units, and solenoid valves.\u003c\/p\u003e\u003cp\u003eOn the network side, it connects to an NMEA 2000 backbone via a Micro-C port (1 LEN), so heading sensors, pilot controllers, and compatible multifunction displays can all share data on the same bus. It can work with Virtual Rudder Feedback on planing outboard and sterndrive boats, and it also supports physical rudder feedback options including Simrad RF25 and resistive rudder sensors.\u003c\/p\u003e\u003cp\u003eThe housing is rated IPx5 for spray and washdowns, with an operating temperature range of -25 C to +55 C. Keep it at least 500 mm (20 inches) from a magnetic compass and mount it where cabling and service access stay practical.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFor boats up to 10 m (33 ft) using low-current hydraulic pumps, mechanical drives, hydraulic linear drives, or solenoid valves\u003c\/li\u003e\n\u003cli\u003e9 to 31.2 V DC input for 12 V and 24 V electrical systems, with a recommended 20 A fuse\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 Micro-C networking (1 LEN) for integration with compatible sensors, controllers, and displays\u003c\/li\u003e\n\u003cli\u003e8 A continuous drive output for reversible motor or solenoid steering control, sized for low-current drives\u003c\/li\u003e\n\u003cli\u003eSeparate engage output for bypass or clutch circuits up to 3 A\u003c\/li\u003e\n\u003cli\u003eVirtual Rudder Feedback support for planing outboard and sterndrive installations where a physical rudder sensor is impractical\u003c\/li\u003e\n\u003cli\u003eRudder feedback support for Simrad RF25 and resistive rudder sensors when a physical reference is required\u003c\/li\u003e\n\u003cli\u003eIPx5 water resistance and shock and vibration performance aligned with EN60945 expectations for marine electronics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNAC-2 autopilot computer\u003c\/li\u003e\n\u003cli\u003ePower cable, 2 m\u003c\/li\u003e\n\u003cli\u003eDrive cable, 2 m\u003c\/li\u003e\n\u003cli\u003eRudder feedback cable, 2 m\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 network cable, 0.6 m\u003c\/li\u003e\n\u003cli\u003eMicro-C T-Joiner\u003c\/li\u003e\n\u003cli\u003eFixing screws (4)\u003c\/li\u003e\n\u003cli\u003eWarranty card and literature pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis unit is typically mounted below decks close to the steering drive to keep high-current drive wiring short and tidy. Choose a location that stays out of standing water and away from engine heat, and plan the cable routes so connectors are protected from chafe and can be inspected later without tearing the boat apart.\u003c\/p\u003e\u003cp\u003eIf you are using a 24 V drive configuration, the system needs a 24 V supply to provide 24 V output. In mixed-voltage boats, confirm the drive unit and solenoids match the selected drive voltage before powering up.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003ePower it from the vessel DC distribution through a 20 A fuse, using proper marine wiring practices for vibration and corrosion control. The NAC-2 joins the NMEA 2000 backbone with its Micro-C connection, so it can share heading, steering, and pilot control with the rest of the network. It also supports an external hardwired input for functions like an Auto\/Standby button or SteadySteer, depending on how you configure the system.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eConfirm that your steering pump, mechanical drive, or solenoid valve falls within the NAC-2 low-current drive requirements, and that your pilot controller or multifunction display is compatible on the NMEA 2000 network. Virtual Rudder Feedback can reduce hardware in planing outboard and sterndrive setups, while boats that need a true rudder reference can use RF25 or a resistive rudder feedback sensor.\u003c\/p\u003e\u003cp\u003eThis is a good match for small cruisers and center consoles with hydraulic steering, as well as compact sailboats and displacement hulls where a low-current drive is appropriate and rudder feedback can be provided when needed.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eThere are no user-serviceable parts inside the unit. Periodically check connector seating and cable strain relief, and keep the installation area clean so salt buildup and moisture do not work their way into plugs and terminals.\u003c\/p\u003e","brand":"Simrad","offers":[{"title":"Default Title","offer_id":52269086376117,"sku":"QBP767996","price":987.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298529_qbp767996.jpg?v=1771541787","url":"https:\/\/www.qualityboatparts.com\/products\/qbp767996","provider":"Quality Boat Parts","version":"1.0","type":"link"}
