This architecture ensures effective channel-to-channel isolation, preventing common-mode noise and ground loops from affecting measurement precision in distributed control environments. The module facilitates accurate RTD signal processing with minimal temperature drift, capped at 30 ppm\/deg C. It is optimized for integration with 4-wire, 3-wire, or 2-wire RTD configurations, provided the total resistance per wire does not exceed 40 ohms.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the NFAR181-S00\/R8S0 compatible with hot-swapping under power?\u003c\/p\u003e\n\u003cp\u003eA: Yes, this module supports hot-swapping within the N-IO system environment, allowing for replacement without interrupting the communication of other modules on the same node.\u003c\/p\u003e\n\u003cp\u003eQ: What is the significance of the 1500 V AC withstanding voltage specification?\u003c\/p\u003e\n\u003cp\u003eA: This rating defines the electrical isolation barrier between the field input terminals and the internal system backplane, protecting the controller circuitry from high-voltage transients or surges originating from the field side.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the module is securely latched into the dedicated base plate to maintain electrical contact with the backplane bus.\u003c\/li\u003e\n\u003cli\u003eUse shielded twisted-pair cabling for all RTD inputs; ensure the cable shield is grounded at the instrument or cabinet ground bar to minimize electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eVerify that the wire resistance for each channel remains below the 40 ohms limit to prevent measurement bias.\u003c\/li\u003e\n\u003cli\u003eMaintain a clean environment free of conductive dust when accessing terminal blocks to prevent accidental shorts across the 12 input channels.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49981858349308,"sku":"NFAR181-S00\/R8S0","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/NFAR181-S00R8S0.jpg?v=1784079916","url":"https:\/\/www.electronicplc.com\/es\/products\/nfar181-s00-r8s0-rtd-input-module-yokogawa","provider":"Electronic PLC","version":"1.0","type":"link"}
