FUNCTIONAL DESCRIPTION:
The 5466-268 is a Speed Sensor/Driver Module manufactured and designed by Woodward as part of the 5000 Series used in Woodward Control Systems. The Woodward 5466-268 Speed Sensor/Driver Module is designed to interface with rotational speed sensors, such as magnetic pickups or proximity probes, mounted on turbines, engines, or other rotating machinery. Its primary function is to condition and process the raw speed signals from these sensors, converting them into clean, reliable outputs suitable for the control system�s CPU or governor logic. By acting as a signal conditioner and driver, it ensures accurate speed feedback is provided for engine or turbine regulation, overspeed protection, and performance monitoring. The module integrates into the 5466 series control rack alongside other I/O and driver modules, forming a critical part of industrial control systems where precise and dependable speed information is essential for both operational efficiency and safety.
INPUT/OUTPUT SIGNAL:
The input stage of the module incorporates high-impedance differential inputs with Schmitt-trigger circuits to reject electrical noise and ensure reliable edge detection under varying sensor amplitudes and environmental conditions. Signal conditioning circuits provide amplitude normalization, frequency shaping, and isolation, producing a clean square-wave output that accurately represents the shaft�s instantaneous rotational speed.
INSTALLATION AND MOUNTING:
The module interfaces with the rack through a multi-pin backplane connector, which provides both power and signal pathways, ensuring a stable electrical connection and minimizing signal degradation. Correct installation requires that the module be fully seated in the backplane slot, with front retention clips engaged to prevent mechanical loosening in high-vibration environments.
Optimal operation demands vertical orientation within the rack to facilitate passive heat dissipation, preventing thermal stress on sensitive analog and digital circuitry. A minimum clearance of 20�25 mm around the module is recommended to allow airflow and prevent heat accumulation from adjacent modules. All sensor and power wiring should be routed separately, with shielded cables for high-frequency speed inputs to reduce electromagnetic interference and preserve signal fidelity. The module�s chassis must be properly grounded to the rack frame, which acts as a reference for input signal conditioning circuits and provides protection against voltage transients.

What is Woodward 5466-268?
The 5466-268 is a Speed Sensor/Driver Module from Woodward�s 5000 Series designed to interface with rotational speed sensors such as magnetic pickups or proximity probes. It conditions raw sensor pulses through amplitude normalization, filtering, and pulse shaping, producing a stable digital output compatible with CPU or governor modules. The module provides real-time rotational speed data, enabling precise engine or turbine regulation and overspeed protection.
What types of speed sensors are compatible with the Speed Sensor/Driver Module?
The module is compatible with magnetic pickups (MPUs) and proximity probes that generate pulse signals proportional to shaft rotation. It supports sensors producing frequencies up to 10 kHz and voltages ranging from 0.5 V to 30 V peak. High-impedance differential inputs ensure reliable operation with various industrial sensor types.
How does the 5466-268 process input signals?
The module uses signal conditioning circuits that perform amplitude normalization, Schmitt-trigger edge detection, filtering, and isolation. This converts noisy, variable-amplitude pulses into a clean, stable square-wave output. The conditioning ensures accurate real-time speed monitoring and prevents erroneous signals from affecting control logic.
What is the output signal specification of the Speed Sensor/Driver Module?
The output is a conditioned digital signal with a buffered, low-impedance drive suitable for CPU or governor inputs. It maintains the frequency and phase integrity of the input pulses for precise rotational speed computation. The output supports loads of 10�20 mA, ensuring compatibility with downstream modules in the 5466 control rack.
