Product Overview

The Woodward 9905-971 Rev(L) is a 16-channel digital input module designed for use within the LinkNet distributed I/O architecture. It collects ON/OFF status signals from field devices such as switches and auxiliary contacts and transmits them to the central control system in real time.
This unit is supplied as 100% brand new original equipment, incorporating Rev(L) hardware improvements for enhanced reliability, thermal stability, and long-term industrial performance.

Technical Specifications

Engineering Advantages

• Distributed Architecture: Enables placement near field devices, reducing wiring complexity and installation cost.

• Enhanced Safety Monitoring: Latent fault detection identifies hidden internal issues before they affect critical operations.

• Industrial Durability: Designed to withstand vibration, ताप cycling, and harsh conditions typical of turbine and engine environments.

• Signal Conditioning: Filters noise and contact bounce to ensure stable and accurate digital input signals.

• Scalable System Design: Multiple modules can be integrated into the LinkNet network for expanded I/O capacity.

FAQs

Does it support sinking and sourcing inputs?
It is designed for standard 24 VDC discrete signals compatible with dry contacts. Wiring configuration depends on the system’s LinkNet setup.

What does Rev(L) indicate?
Rev(L) represents the latest hardware revision with improved electronic components and enhanced thermal performance compared to earlier revisions.

How does it communicate with the controller?
It communicates via the LinkNet network, enabling deterministic and synchronized data exchange with the central CPU.

What is the product condition?
This module is supplied as 100% brand new original equipment, with factory packaging and no prior usage.
