Designed to maintain signal integrity during extreme rotor dynamics, the module conditions high-density RTD and thermocouple inputs before passing digitized temperature values across the 3500 backplane bus. The hardware design prevents eddy-current probe scaling interference or cross-channel coupling from skewing critical thermal monitoring thresholds on rotating shafts.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 172109-01 module accept non-isolated thermocouple inputs?\u003c\/p\u003e\n\u003cp\u003eA: No, the 3500\/65 system architecture strictly requires isolated tip thermocouples to prevent stray ground loop currents from corrupting internal channel conditioning circuits.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module execute voting in Triple Modular Redundant (TMR) rack configurations?\u003c\/p\u003e\n\u003cp\u003eA: In TMR setups, three adjacent 3500\/65 modules receive identical sensor inputs, and the 3500 TMR Rack Interface Module (RIM) executes channel-to-channel output voting against programmed percentage tolerances to trigger system alarms.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify backplane power is off or follow hot-swap procedures before inserting the I\/O module into the rear slot of the 3500 rack.\u003c\/li\u003e\n\u003cli\u003eMaintain minimum 360-degree shield coverage at the field wiring terminal blocks; terminate sensor shields directly to the chassis ground bus bar.\u003c\/li\u003e\n\u003cli\u003eEnsure all terminal screws are torqued to specified field limits (0.5 to 0.6 Nm) to avoid contact resistance drift on low-millivolt thermocouple loops.\u003c\/li\u003e\n\u003cli\u003eRoute RTD and TC field wiring in dedicated grounded conduits, separated from high-voltage AC motor lines by at least 300 mm.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45377590657139,"sku":"172109-01","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/125744-02_2.jpg?v=1787215276","url":"https:\/\/www.dcssupplier.com\/products\/bently-nevada-172109-01-temperature-monitoring-modules","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
