I. Product Overview

WOODWARD 5441-889 is a high-density digital signal interface module specifically designed for the MicroNet and NetCon 5000 control systems. As a bridge connecting the system with on-site switches, valves, relays, and indicator lights and other digital devices, it is responsible for the collection and drive control of discrete signals. This module is a discontinued model, and the market mainly circulates refurbished / spare parts. 

II. Core Functional Characteristics

High-density digital I/O: Provides 32 isolated digital input (DI) and 32 isolated digital output (DO), totaling 64 points, effectively saving rack space.

Full electrical isolation: Three-terminal isolation (2500V AC) for input, output, and system side, effectively suppressing on-site interference and protecting the core control system.

Industrial standard signals:

Input: Compatible with 24V DC active/passive switch signals, supports source-type / leakage-type wiring.

Output: 24V DC solid-state relay (SSR) output, without contacts, long life, fast response.

Hot-swappable design: Supports safe module insertion and removal while the system is powered on, facilitating online maintenance and replacement.

Status indication: Each channel is equipped with an independent LED indicator, real-time displaying input on/off and output status, facilitating quick diagnosis.

Real-time diagnosis: Equipped with output short-circuit protection, overcurrent alarm, and module self-check functions, triggering system alarm in case of faults.

Wide temperature industrial grade: Suitable for extreme industrial environments, passing CE, UL, Class I Div II explosion-proof certifications.
