Frequently Asked Questions (FAQ)

Q1: What types of transducers are compatible with the 3500/50 Tachometer Module?
A1: It supports 1 to 2 proximity probe transducers or magnetic pickups. Magnetic pickups are not recommended for reverse rotation or zero speed detection due to potential false indications.

Q2: What is the maximum speed the module can monitor?
A2: The 3500/50 Tachometer Module can monitor shaft speeds up to 99,999 rpm with an input frequency limit of 20 kHz.

Q3: Does this module provide protection features such as overspeed control?
A3: No, this module is not intended for speed control or overspeed protection. It is not designed with the protective redundancy or reaction speed required for such safety-critical functions.

Q4: Can this module be used to replace a Keyphasor module in the rack?
A4: Yes, it can be configured to supply conditioned Keyphasor signals to the 3500 rack backplane, removing the need for a separate Keyphasor module.

Q5: What are the output signal capabilities of the module?
A5: It provides 4–20 mA analog outputs per channel, proportional to full-scale speed or acceleration values. Outputs are unaffected by short circuits.

Q6: Is it possible to adjust alarm setpoints and delays for each channel?
A6: Yes, Alarm 1 and Alarm 2 setpoints and delays are fully programmable using the configuration software.

Q7: How accurate is the speed measurement?
A7: Accuracy varies by speed range—within ±0.1 rpm under 100 rpm, ±1 rpm from 100 to 10,000 rpm, and ±0.01% for speeds above 10,000 rpm.

Q8: What are the module’s dimensions and weight?
A8: The monitor module measures 241.3 x 24.4 x 241.8 mm, and with a barrier I/O module, the total weight is approximately 0.91 kg.
