Eddy-Current Probe Scaling and Gap Validation
The module interfaces directly with 3300 series proximity probes, requiring strict adherence to eddy-current probe scaling factors based on target material composition (steel vs. aluminum). The front-end signal conditioning circuitry validates gap voltage against a standard -10 VDC target window. Deviations outside this range trigger a signal fault without interrupting the buffered output stream, ensuring continuous rotor dynamics data acquisition while maintaining open-circuit detection integrity.
Frequently Asked Questions
Q: Does the 3500/25 support hot-swap insertion into a live rack?
A: No. The module must be installed in a de-energized rack. Live insertion can cause transient spikes that disrupt the backplane communication bus and potentially damage the input signal conditioning ASICs.
Q: What is the maximum cable run length for the Keyphasor input signal?
A: Maintain total conductor length under 305 meters (1000 feet) for proximity probes to prevent signal attenuation below the threshold voltage required for stable triggering.
Q: How does the module handle crosstalk between channels?
A: The 3500/25 utilizes isolated input filtering and independent signal return paths. Physical separation of input wiring by at least 300 mm is required to suppress electromagnetic crosstalk in high-noise environments.
Field Installation Guidelines
- Grounding: Connect the shield drain wire of the proximity probe cable directly to the ground terminal on the I/O module. Do not connect the shield at the probe end to prevent ground loops.
- Terminal Torque: Apply 0.8 N·m (7 lb·in) of torque to all field wiring terminals on the 125800-01 I/O module to ensure gas-tight connections.
- Clearance: Ensure a minimum of 25 mm clearance exists above the BNC connectors on the front panel for coaxial cable bend radius compliance.
