Frequently Asked Questions (FAQ)

Q1: What is the main purpose of the 3500/25 126648-02 Isolated Keyphasor I/O Module?
A1: It is designed to condition and isolate Keyphasor signals, especially when they are shared across multiple systems, such as a control system and monitoring system.

Q2: Can this module be used with both magnetic pickups and proximitor sensors?
A2: Yes. It is primarily intended for magnetic pickups but is also compatible with proximitor sensors when an external power supply is used.

Q3: Does the isolated I/O version affect phase accuracy?
A3: Yes. It introduces slightly higher phase shift than the non-isolated version, making it more suitable for speed measurement than precise phase analysis.

Q4: What are the input signal voltage limits for the isolated version?
A4: The input voltage range is from +5 V to -11 V for the isolated I/O module.

Q5: What is the minimum operating speed for reliable input detection?
A5: Magnetic pickups require a shaft speed above 200 rpm to generate sufficient signal for detection.

Q6: What kind of buffered output is available for this module?
A6: Two buffered Keyphasor outputs are available at both the front and rear (Euro connectors and coaxial jacks).

Q7: How is the signal threshold configured on this module?
A7: It supports both auto-thresholding and manual thresholding, with manual settings ranging from 0 to -20 Vdc.

Q8: What is the power supply provided to each transducer channel?
A8: The module supplies -24 Vdc at a maximum of 40 mA per channel.
