Product Overview
The 3500/25 149369-01 is a half-height, dual-channel Keyphasor module that installs in any 3500-series rack.
It accepts signals from eddy-current probes or magnetic pickups and converts each passing of a shaft key-way into a high-precision digital pulse. These pulses provide the speed reference and phase marker required for ordered vibration analysis, vector balancing, speed alarming and event timing throughout the 3500 system.

Key Benefits
Ø Dual-channel density – two completely independent Keyphasor inputs in one half-slot save rack space.
Ø Sub-degree accuracy – 0.1° phase resolution enables high-precision vector balancing and order tracking.
Ø Wide speed range – 0.1 Hz to 50 kHz covers everything from slow-speed extruders to high-speed centrifuges.
Ø Auto-threshold & gain – adaptive circuitry maintains reliable triggering on worn or coated targets.
Ø Hot-swap & hot-spare – replace or switch modules on-line without shaft marking re-work.
Ø Seamless integration – pulse is automatically distributed to every 3500 monitor for speed-corrected alarms and FFT order analysis.
Ø Harsh-environment ready – –40 °C start-up and conformal-coated PCB for offshore and arctic duty.
All items are factory-new, sealed, and supported by PLC Autocontroller with same-day quotation and worldwide overnight delivery.
