The module processes high-frequency encoder feedback and differential pulse inputs across 4 independent counter channels to execute real-time speed and position tracking. Mounted on the central FA-M3 backplane, the unit interfaces directly with the central processor bus to transfer 32-bit accumulated counter counts at frequencies up to 100 kHz per channel.\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\u003eF3NC34-0N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.15 kg net (0.91 kg shipping weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e28.9 mm W x 100 mm H x 83.2 mm D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e3 W maximum (5 VDC logic bus supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e4 independent counter\/positioning channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Types\u003c\/td\u003e\n\u003ctd\u003eDifferential pulse, A\/B phase quadrature encoder, contact ON\/OFF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Frequency\u003c\/td\u003e\n\u003ctd\u003eUp to 100 kHz per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounter Range\u003c\/td\u003e\n\u003ctd\u003e32-bit counter capacity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eOptical isolation between input channels and system bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel-to-Channel Isolation Integration\u003c\/h3\u003e\n\u003cp\u003eThe F3NC34-0N module features high-speed optocouplers to establish physical galvanic isolation between external pulse feedback lines and the internal 5 VDC system bus. When operating in control enclosures alongside analog modules processing 4-20 mA HART loop protocol signals or delicate millivolt CJC (cold junction compensation) sensor wires, this optical isolation blocks ground loops and high-frequency common-mode noise. By isolating field-side encoder signals, the module prevents high-frequency switching transients from coupling into sensitive process instrumentation loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What action occurs if input pulse frequencies exceed the 100 kHz limit on a channel?\u003c\/p\u003e\n\u003cp\u003eA: Pulse rates exceeding 100 kHz can cause missed counts or timing skew in the 32-bit counter registers, compromising position accuracy without triggering a hardware shutdown.\u003c\/p\u003e\n\u003cp\u003eQ: Can the F3NC34-0N module be installed or removed while the FA-M3 backplane is energized?\u003c\/p\u003e\n\u003cp\u003eA: No. Disconnect power to the main FA-M3 rack before removing or installing the module to avoid backplane pin damage and logic bus latch-up faults.\u003c\/p\u003e\n\u003cp\u003eQ: How does optical isolation protect system logic during field-side wiring faults?\u003c\/p\u003e\n\u003cp\u003eA: The internal optical barriers insulate system electronics against field voltage surges and transients, preventing external electrical faults on encoder lines from corrupting central backplane logic.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShielded Cable Termination:\u003c\/strong\u003e Connect quadrature encoder and pulse input lines using twisted-shielded pair cables, terminating the shield braid to functional earth (FE) at the panel entry point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Line Separation:\u003c\/strong\u003e Route high-speed pulse feedback wiring in separate wire ducts away from AC power conductors and VFD motor cables with at least 200 mm physical clearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Slot Insertion:\u003c\/strong\u003e Seat the module firmly into the FA-M3 base unit slot, tightening the upper locking screw to establish chassis ground continuity and prevent vibration loosening.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Thermal Clearance:\u003c\/strong\u003e Maintain a clear vertical space of at least 50 mm above and below the module rack to allow natural air convection within ambient operating limits.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43796461322330,"sku":"F3NC34-0N","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/760..jpg?v=1786072285","url":"https:\/\/www.spareoil.com\/products\/yokogawa-f3nc34-0n-fa-m3-positioning-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
