The module executes multi-channel analog-to-digital (A\/D) signal translation to transform external voltage source inputs into proportional digital registers utilized by the central processor rack. It employs hardware-level photocoupler components to decouple the low-voltage internal system logic lines from external field-side cabling 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\u003eF3AD04-0N\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\u003ePlatform\u003c\/td\u003e\n\u003ctd\u003eFA-M3 PLC Series\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\u003e170 g (0.30 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e28.9 x 100 x 83.2 mm\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\u003e210 mA at 5 V DC (internal logic draw)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Configuration\u003c\/td\u003e\n\u003ctd\u003e4 voltage channels (shared common negative loop topology)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Ranges\u003c\/td\u003e\n\u003ctd\u003e0 to 5 V DC, 1 to 5 V DC, -10 to +10 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAbsolute Maximum Input Rating\u003c\/td\u003e\n\u003ctd\u003ePlus or minus 18 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Mechanism\u003c\/td\u003e\n\u003ctd\u003ePhotocoupler isolation (input terminals to internal circuitry)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDielectric Withstand Voltage\u003c\/td\u003e\n\u003ctd\u003e500 V DC for 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Input Resistance\u003c\/td\u003e\n\u003ctd\u003e1 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Conversion Resolution\u003c\/td\u003e\n\u003ctd\u003e12-bit (1.4 mV step at 0-5 V \/ 1-5 V DC; 5.7 mV step at -10 to +10 V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase Conversion Speed\u003c\/td\u003e\n\u003ctd\u003e1 ms multiplied by the number of active input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Output Scaling\u003c\/td\u003e\n\u003ctd\u003eAdjustable software mapping from -20000 to +20000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination Interface\u003c\/td\u003e\n\u003ctd\u003e10-point terminal block with M3.5 screw connections\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDistributed System Architecture and Backplane Communication\u003c\/h3\u003e\n\u003cp\u003eThe module shares process variable states across the system backplane by adhering to strict backplane bus communication velocity limits assigned by the base rack slot controller. The multi-channel multiplexing sequence allows variable configuration changes to expand system scaling parameters without introducing signal jitter across high-density adjacent cards. This internal bus coupling configuration maintains firmware flash compatibility parameters across legacy FA-M3 bases, assuring deterministic register access and software digital filtering operations during continuous multi-channel operational cycles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does selecting a software digital filter modify the hardware conversion speed?\u003c\/p\u003e\n\u003cp\u003eA: The underlying hardware conversion rate remains fixed at 1 ms per enabled channel, but configuring internal digital software smoothing algorithms adds sequential execution cycles before updating the final register values on the backplane bus.\u003c\/p\u003e\n\u003cp\u003eQ: Can an external current transmitter loop interface directly into these voltage terminals?\u003c\/p\u003e\n\u003cp\u003eA: No, the input architecture reads voltage potentials exclusively; a high-precision external precision resistor matrix must be wired across the positive and negative terminals to convert a 4-20 mA current signal into a standard 1-5 V DC potential.\u003c\/p\u003e\n\u003cp\u003eQ: What happens if an input voltage spikes to plus or minus 15 V DC on a 0-5 V DC configured channel?\u003c\/p\u003e\n\u003cp\u003eA: The channel digital value will saturate at its maximum software limit, but the hardware will not sustain damage because the internal buffer circuits are rated to withstand up to an absolute maximum of plus or minus 18 V DC continuously.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Screw Tightening:\u003c\/strong\u003e Secure all field conductor ends into the M3.5 terminal block clamping plates using a torque driver set strictly within standard mechanical panel limits to prevent localized thread stripping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Negative Constraints:\u003c\/strong\u003e Group field input sensor returns appropriately, noting that all 4 input channels on the terminal block assembly share a single, non-isolated common internal negative bus configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Shield Grounding:\u003c\/strong\u003e Terminate the outer copper braided shielding of all incoming voltage signal cables at a single point on the enclosure instrument earth plate to bypass high-frequency common-mode noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Insertion Alignment:\u003c\/strong\u003e Insert the module along the chassis tracking slots to guarantee full engagement of the internal backplane multipin interface before locking the base panel retention mechanism.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43683723346010,"sku":"F3AD04-0N","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/627..jpg?v=1784597731","url":"https:\/\/www.spareoil.com\/products\/f3ad04-0n-fa-m3-yokogawa-analog-input-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
