This architecture effectively suppresses ground loops in large-scale installations. The module supports loop-powered transmitters, delivering a supply voltage of 20.2 to 29.3 V DC with a current limit of 25 mA per channel. With a temperature drift specification of 0.01% per deg C, the module ensures measurement stability in varying ambient industrial conditions.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the NFAI135-S50 support hot-swapping while the STARDOM controller is in operation?\u003c\/p\u003e\n\u003cp\u003eA: No, module removal must be performed while the power supply to the specific base unit is disconnected to prevent potential electrical arcing or system bus communication errors.\u003c\/p\u003e\n\u003cp\u003eQ: What is the behavior of the input resistance when the module power is removed?\u003c\/p\u003e\n\u003cp\u003eA: When power is OFF, the input resistance transitions to a high-impedance state of at least 500 kOhm, effectively isolating the field loop from the module circuitry.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the module is securely seated in the designated slot of the base unit and locked using the provided latching mechanism.\u003c\/li\u003e\n\u003cli\u003eUtilize the \/CCC01 MIL connector cable for all field wiring to maintain the integrity of the shielding and environmental protection.\u003c\/li\u003e\n\u003cli\u003eRoute analog signal cables separately from high-voltage AC power lines to minimize induced electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eVerify that the 24 V DC external power supply is within the 20.2-29.3 V DC range to ensure proper operation of connected transmitters.\u003c\/li\u003e\n\u003cli\u003eObserve the 100 ms step response time when configuring loop control parameters in the STARDOM software environment to avoid overshoot or instability.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":50198945956092,"sku":"NFAI135-S50","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/NFAI135-S501.jpg?v=1784252689","url":"https:\/\/www.electronicplc.com\/es\/products\/yokogawa-nfai135-s50-isolated-analog-input-module","provider":"Electronic PLC","version":"1.0","type":"link"}
