I. Product Overview

WOODWARD 5441-689 is an industrial-grade isolated digital input/output (I/O) module specifically designed for the MicroNet and NetCon 5000 control systems. It is tailored for connecting industrial field devices with high voltages and large currents (such as solenoids, high-power relays, indicator lights, circuit breaker auxiliary contacts, etc.), providing dual voltage compatibility of 24VDC and 120VAC signal interfaces to achieve safe isolation between the control system and the high-voltage circuits and signal interaction. This module is a discontinued model, and the market mainly circulates refurbished / spare parts. 

II. Core Functional Features

Wide Voltage Digital I/O: Supports dual voltage input/output of 24VDC and 120VAC, suitable for most industrial site equipment.

Full Electrical Isolation: Three-terminal full isolation (2500V AC) for input, output, and system power supply, effectively protecting the control system from strong electrical interference and surge impacts.

Rich I/O Points: Provides 16 isolated digital inputs (DI) and 8 relay outputs (DO), meeting the interlock and control requirements of complex equipment.

High-load Relay Output: Output contacts with a capacity of up to 5A @ 250VAC / 30VDC, capable of directly driving high-power loads without the need for external intermediate relays.

High-speed Signal Processing: Input signal response time < 5ms, supporting high-speed status monitoring and event capture.

Status LED Indication: Each I/O is equipped with an independent LED status indicator, clearly displaying the on-off status, facilitating quick diagnosis and maintenance.

Hot Swap Design: Supports hot swapping (On-the-fly replacement), allowing module replacement while the system is running, without affecting the normal operation of other modules.

Industrial Grade Reliability: Wide temperature, shock-resistant, dust-proof design, compliant with CE and UL certifications, suitable for harsh environments such as power plants, petrochemicals, and metallurgy.
