FAQ
A1: It provides a once-per-turn timing reference used to measure shaft speed, phase, and vibration vector.Q2: Can the Enhanced Keyphasor Module replace older versions?
A2: Yes, it maintains full form, fit, and function compatibility with legacy Keyphasor modules.
Q3: How many Keyphasor signals can a 3500 system accept?
A3: Up to four in normal configurations, or eight when using paired modules.
Q4: Does the module support TMR configurations?
A4: Yes. Two modules can operate in parallel for redundancy in TMR systems.
Q5: Can the module operate in hazardous locations?
A5: Yes, when configured with appropriate isolated I/O modules and installation practices.
