FAQ
Frequently Asked Questions (FAQ)
Q1: What type of inputs can the 3500/50 Tachometer Module accept?
A1: It accepts up to two transducer signals, either from proximity probes or magnetic pickups.
Q2: Can the module be used as a speed control or overspeed protection system?
A2: No, it is not designed for speed control or overspeed protection. It lacks the necessary response speed and redundancy.
Q3: What is the maximum shaft speed it can monitor?
A3: The module can handle shaft speeds up to 99,999 RPM with a maximum input frequency of 20 kHz.
Q4: Can it generate alarms based on speed thresholds?
A4: Yes, Alarm 1 and Alarm 2 thresholds can be configured via software for each channel.
Q5: Does the module provide buffered outputs?
A5: Yes, each channel has a coaxial connector on the front panel for buffered transducer output, also available on the I/O module.
Q6: Is a separate Keyphasor module required when using this tachometer module?
A6: No, the 3500/50M can supply conditioned Keyphasor signals to the rack backplane.
Q7: What is the power consumption of the module?
A7: Typical power consumption is 5.8 Watts.
Q8: What are the available transducer triggering options?
A8: The module supports both auto threshold (for signals >0.0167 Hz) and manual threshold settings from +9.5 Vdc to -23.5 Vdc.
