The module acquires pulse train inputs up to 50 kHz, executing single-pulse width measurement and cumulative counting up to 999,999,999 counts. The internal signal conversion stage transforms high-frequency pulse data into 4-20 mA analog output loops for downstream process actuators and monitoring sub-assemblies. Integrated channel-to-channel isolation prevents electrical noise and potential offsets from degrading backplane communications.\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\u003eAAP849-S00\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\u003e0.70 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e130 x 120 x 30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +50 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e7.3 W maximum (1460 mA at 5 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePulse Input Channels\u003c\/td\u003e\n\u003ctd\u003e8 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Output Channels\u003c\/td\u003e\n\u003ctd\u003e8 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Type\u003c\/td\u003e\n\u003ctd\u003ePulse (frequency and count)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal Type\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC analog signal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003eUp to 50 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounting Range\u003c\/td\u003e\n\u003ctd\u003e0 to 999,999,999 counts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Load Resistance\u003c\/td\u003e\n\u003ctd\u003e250 ohm nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Isolation\u003c\/td\u003e\n\u003ctd\u003eOptical isolation (1500 VAC dielectric withstand)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eField Control Unit base plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Loop \u0026amp; Signal Isolation Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe hardware features channel-to-channel optical isolation rated for 1500 VAC dielectric withstand, specifically designed to operate alongside 4-20 mA HART loop protocol architectures. Internal optical isolation decouples field-side grounding paths from the central processing logic, eliminating common-mode noise corruption during high-speed pulse acquisition. The module processes analog output conversions while executing continuous onboard diagnostics to verify circuit health and signal line continuity across all field wiring connections.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the AAP849-S00 support live insertion and removal during controller operation?\u003c\/p\u003e\n\u003cp\u003eA: The module supports hot-swapping on active base plates. Technicians can replace the card without interrupting the Field Control Unit execution cycle, provided the multi-pin terminal connector is disengaged cleanly.\u003c\/p\u003e\n\u003cp\u003eQ: What precautions are necessary regarding pulse input signal wiring?\u003c\/p\u003e\n\u003cp\u003eA: High-frequency pulse lines up to 50 kHz require twisted-pair shielded cabling. Ground the braid shield at a single point on the cabinet earthing bar to prevent electromagnetic interference from inducing stray counts.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eIsolate external 24 VDC auxiliary loop supplies before inserting or disconnecting the module terminal interface.\u003c\/li\u003e\n\u003cli\u003eAlign the module circuit board edge with the designated slot guide rails inside the Field Control Unit rack.\u003c\/li\u003e\n\u003cli\u003eSlide the card into the backplane connector until the upper and lower retaining levers lock securely.\u003c\/li\u003e\n\u003cli\u003eFasten field wiring connectors tightly to the front plate interface to ensure low-impedance electrical contact.\u003c\/li\u003e\n\u003cli\u003eGround all cable shields to the system cabinet earthing bus using dedicated grounding clamps to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum separation distance of 200 mm between pulse signal cables and high-voltage AC power distribution lines.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43865949405274,"sku":"AAP849-S00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/835..jpg?v=1787102828","url":"https:\/\/www.spareoil.com\/products\/8-channel-pulse-analog-module-yokogawa-aap849-s00","provider":"SpareOil Automation","version":"1.0","type":"link"}
