How do I choose between the ±25 mA and ±50 mA servo output ranges?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eCheck the servo actuator or amplifier input specification. Select the supported range and confirm its allowable load resistance before connecting the output.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e2. Can the module accept different LVDT excitation frequencies across its channels?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The listed excitation frequencies are independently selectable. Match each channel's setting to its connected transducer requirements.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e3. What should I verify when an LVDT replacement produces a different position reading?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eCompare wiring, excitation frequency, transducer range, polarity, and configured scaling. Also inspect the mechanical linkage and verify the reading against an approved reference.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e4. Does the 5 ms scan cycle determine the complete turbine control response time?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The scan cycle describes module timing.
