For proper calibration, the module validates gap voltage, typically targeting a -10 VDC nominal center point within the linear range of the probe. Rotor position monitoring relies on the conversion of these gap voltages into engineering units. Signal integrity is maintained through active cross-talk suppression and digital filtering, ensuring that high-frequency noise from field wiring does not induce jitter in the displacement output.\u003c\/p\u003e\n\u003ch3\u003eOrdering and Packaging\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eStandard module unit (140072-04)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInternal I\/O module (typically required for signal termination)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConfiguration software compatibility: 3500 Rack Configuration Software\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSafety manual and documentation (Electronic format)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSite Installation Procedures\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure the 3500 rack is powered down before inserting or removing the module.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVerify that the transducer shield drain is connected to the designated common ground on the I\/O card to prevent ground loops.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaintain a minimum distance of 50 mm from high-voltage AC cables to reduce electromagnetic interference on signal lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure that the module is fully seated in the rack slot and that the front-panel captive screws are tightened to meet IP67 enclosure integrity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eIs this module hot-swappable in an active 3500 rack?
