The 5464-331 is a Speed Sensor Module designed and manufactured by Woodward for integration within MicroNet and MicroNet Plus turbine control systems. Designed to monitor the rotational speed of steam turbines, gas turbines, hydro turbines, and large industrial engines, this module provides the critical frequency measurement inputs needed for prime mover speed governing and over-speed protection. By conditioning raw sinusoidal or square-wave frequency signals from speed sensors mounted on the target gear wheel, the 5464-331 converts high-velocity rotational pulses into ultra-precise digital data streams for direct processing by the central system CPU.
HIGH-SPEED FREQUENCY ACQUISITION & SIGNAL ISOLATION:
Equipped with 4 independent speed channels, the 5464-331 accommodates both passive Magnetic Pick-up Units (MPUs) and active proximity switches. The module utilizes high-speed zero-crossing detection circuits and hardware counters capable of reading frequencies up to 50 kHz with exceptional resolution. To safeguard core system microprocessors against field-side electrical disturbances, the module features 500 VDC galvanic isolation between input channels and the VME backplane bus. Integrated filtering networks suppress high-frequency electromagnetic interference (EMI) and line noise, preventing false speed spikes from corrupting governor calculations.
CONTINUOUS SPEED DIAGNOSTICS & FAULT DETECTION:
The 5464-331 includes onboard signal monitoring to ensure continuous detection of speed measurement anomalies. Front-panel LEDs provide real-time visual indications for power status, pulse activity on each input channel, and hardware fault conditions. The module instantly flags a speed signal fault to the main CPU logic. This allows the control system to execute smooth signal auctioneering, transition to redundant speed channels, or trigger emergency trip procedures to protect plant assets.
