5464-658

Overview

The 5464-658 is a Digital Speed Sensor Module developed by Woodward, designed to deliver precise speed measurements without the need for signal conditioning, potentiometers, or frequent calibration adjustments.

Key Features

• Speed Input Range: 0.5 - 25,000 Hz

• Input Amplitude: 3.5 - 32 Vdc

• Power Supply: 12 Vdc or 24 Vdc, 50 mA max

• Resolution: 12 bits over selected frequency range

• Accuracy: Calibrated to 0.03% full scale

• Fuse Protection: 100 mA fuse per channel (24 Vdc), short circuit protection (12 Vdc)

• Time Stamping: 5 ms resolution for low event and latch

System Operation

• Input Channels: Four speed input channels, each supporting MPU or proximity probes

• Speed Detection: Detects speeds as low as 0.5 Hz, with software capable of handling very low-speed scenarios

• Filter Options: Selectable time constant of 8 ms or 16 ms, adjustable through application software

• Sensor Types: Accepts passive MPUs or proximity probes for each channel

• Fault Detection: Detects failed speed sensors to prevent overspeed conditions

Performance

• Speed Measurement: Provides accurate speed readings without the need for external signal conditioning

• Software Control: Allows easy adjustment and customization through the application program
