WOODWARD 5437-845 Product Detailed Description

Product Model: WOODWARD 5437-845

Brand: WOODWARD (Woodward)

Product Type: 3KHZ Band-stop Filter Board (Notch Filter Board)

Generation Time: 2026-05-18 10:34:44

I. Product Overview

WOODWARD 5437-845 is a dedicated signal filtering circuit board. Its core function is to precisely filter out 3KHz frequency electrical signal interference. It is mainly used in Woodward NetCon, MicroNet, and 505/505E speed control systems, for purifying critical analog signals such as rotational speed, vibration, and pressure, eliminating 3KHz specific frequency noise generated by industrial site motors, frequency converters, and electromagnetic coupling, to ensure the accuracy and stability of control signals.

II. Core Function Characteristics

Precise Band-stop Filtering: Center frequency 3KHz, deep suppression of interference signals in this frequency band

Signal Fidelity: No distortion or attenuation of signals within the passband, ensuring the integrity of the original signal

Plug-and-Play: Directly compatible with 5437 series I/O module slots, no additional wiring required

Industrial-grade Stability: Wide temperature range, high isolation, strong vibration resistance, suitable for strict industrial conditions in power plants / petrochemicals

Compact Design: PCB board structure, lightweight (approximately 70g), saving installation space

Fault Safety: Maintains signal direct connection when the filtering fails, does not interrupt the control system operation
