Woodward 8901-457 Frequency-To-Voltage Signal Converter

Product Description

• The Woodward 8901-457 Converter is a frequency-to-voltage signal converter used in turbine and engine control systems.

• It converts AC voltage or frequency signals from magnetic pickups, tachometers, or other rotational speed sensors into standardized DC voltage signals suitable for controllers and monitoring systems.

• Designed for industrial and power generation environments, it provides precise, reliable signal conversion for accurate speed measurement and control.

• The module is rugged and built to withstand vibration, temperature extremes, and harsh operating conditions.
