Overview

The Woodward 5464-643 discrete input module is engineered to capture digital signals from field devices such as switches, sensors, and relays. It features 32 optically isolated input channels, ensuring robust signal integrity and protection against electrical noise. Each channel includes an LED status indicator, allowing operators to monitor input states in real time.

Moreover, the module supports dry contact or active DC signals within an input voltage range of 18–32 VDC, making it versatile across various industrial applications. In addition, it offers <1 ms scan time, enabling fast response in critical control loops. The module is designed for rack or chassis mounting, and its rugged construction supports operation in extreme temperatures from –40 °C to +70 °C.

This module is widely used in turbine control, engine monitoring, process automation, and power plant instrumentation, where reliable digital input capture is essential.
