The half-height module conditions raw multi-event pulses from proximity probes or magnetic pickups, converting physical shaft rotations into digital timing pulses and RPM metrics. This raw conditioning layer feeds accurate phase angle and speed parameters directly across the internal backplane to vibration monitoring modules for synchronous vector tracking.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e149369-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.91 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e241 mm x 24.4 mm x 163 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-30 to +65 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e7.7 Watts (Maximum)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eEnhanced Keyphasor Module (Half-height)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Configuration\u003c\/td\u003e\n\u003ctd\u003eDual-channel input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Type\u003c\/td\u003e\n\u003ctd\u003eProximity probes or magnetic pickups\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e10 kOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003e0.017 Hz to 100 kHz (1 RPM to 6,000,000 RPM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-1 degree\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuffered Output\u003c\/td\u003e\n\u003ctd\u003e0 to 20 V DC (150 Ohm output impedance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e-24 V DC (via rack backplane)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eMachinery Monitoring and TSI Features\u003c\/h3\u003e\n\u003cp\u003eThe module provides structural management for eddy-current probe scaling when translating physical shaft discontinuities (such as notches or keyways) into uniform timing indicators. Field technicians must complete gap voltage validation to ensure proximity transducer targets maintain stable dc bias levels within the nominal -10 VDC operational envelope. The unit routes continuous speed measurements directly through the internal rack bus, enabling rapid cross-talk suppression and real-time computation of complex rotor dynamics parameters, including shaft centerline plots, polar trends, and filtered vector vectors.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the half-height form factor affect chassis mounting and slot layout constraints?\u003c\/p\u003e\n\u003cp\u003eA: The half-height design occupies one lower or upper half-slot within the 3500 chassis. It requires a half-height wave guide and a matching half-height I\/O module positioned directly behind it to guarantee proper backplane alignment.\u003c\/p\u003e\n\u003cp\u003eQ: What is the calibrated tracking accuracy for raw speed monitoring applications?\u003c\/p\u003e\n\u003cp\u003eA: The module executes speed monitoring calculations with a steady-state accuracy profile of +\/-0.05% of the selected full scale, resolving speed variations down to 0.1 RPM at a 1000 Hz internal sampling loop rate.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransducer Gap Verification:\u003c\/strong\u003e Measure the dc gap voltage of the connected proximity probe using a digital multimeter prior to system startup.
