5462-757 | Woodward | 28-Channel Discrete Input PC Board

Product Overview

The 5462-757 (Revision E) is a high-density discrete input module engineered by Woodward for use in MicroNet, Atlas, and specialized governor control systems. This industrial-grade PC board serves as a critical interface for monitoring digital logic states across 28 independent channels. It is designed to capture on/off signals from various field devices—such as limit switches, proximity sensors, and auxiliary contacts—and translate them into actionable data for the central controller.

As a Revision E module, the 5462-757 (Part Number: 5462-757) features refined circuit protection and enhanced signal stability compared to earlier iterations. Each channel is equipped with localized LED diagnostics, allowing technicians to verify input status at a glance without the need for external testing equipment. Its ruggedized architecture is specifically optimized for the high-vibration and electrically noisy environments common in turbine control and power generation facilities.
