Channel-to-system and channel-to-channel galvanic isolation rated for 500 VAC prevents ground loops and suppresses high-voltage common-mode transients. Integrated hardware filtering eliminates contact chattering, while selectable onboard shunt resistors enable direct current-to-voltage pulse conversion without external signal conditioning modules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the module handle contact chattering on mechanical switch inputs?\u003c\/p\u003e\n\u003cp\u003eA: The module includes a software-selectable hardware filter function designed to suppress mechanical contact chattering and eliminate false pulse counts on slow-moving inputs.\u003c\/p\u003e\n\u003cp\u003eQ: What are the current limiting thresholds for the built-in transmitter power supply?\u003c\/p\u003e\n\u003cp\u003eA: When configured for 12 VDC field power, the internal limiter caps output current at 40 mA (+\/-10%). When set to 24 VDC, output current is limited to 30 mA (+\/-10%).\u003c\/p\u003e\n\u003cp\u003eQ: What happens to the internal shunt resistors when field power is interrupted?\u003c\/p\u003e\n\u003cp\u003eA: The onboard selectable shunt resistor networks revert to an open state whenever module power is lost, preventing unexpected circuit loads on connected field loops.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the NFAP135-S00 securely into the designated slot of the FIO rack chassis prior to applying power. Route field wiring directly to the pressure clamp terminals, verifying that conductor insulation is stripped back cleanly to ensure gas-tight contact. Maintain clear separation between high-voltage power leads and low-level pulse signal lines within cabinet wireways. Connect all signal shielding to the designated cabinet earth ground at a single termination point to prevent noise coupling into high-frequency input channels.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43831989600346,"sku":"NFAP135-S00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/383.1_1b7996d7-c1b5-4721-8ab0-0175f8bffa2a.jpg?v=1786503527","url":"https:\/\/www.spareoil.com\/products\/pulse-input-module-yokogawa-nfap135-s00-stardom","provider":"SpareOil Automation","version":"1.0","type":"link"}
