The Woodward 9905-970 LinkNet 6 Channel Analog Input Module (100 Ohm RTD) 

is a distributed I/O module designed for turbine control and industrial automation systems. It is part of the Woodward LinkNet™ 9900 series, used in MicroNet and turbine control architectures.

This module is specifically designed to interface with 100 Ohm Resistance Temperature Detectors (RTDs), allowing precise temperature measurement across multiple points. It supports six independent input channels, enabling simultaneous monitoring of critical system parameters such as turbine temperatures, bearings, and process conditions.

The module communicates with the control system through the LinkNet network, acting as a distributed node that sends real-time sensor data to the main controller. This allows optimized control, improved safety, and efficient system operation.

Designed for industrial reliability, the module supports 3-wire RTD configurations, reducing measurement errors caused by lead resistance. It also includes built-in diagnostics and reference voltage checking to ensure accurate signal conversion and fault detection.

? Key Features

  • 6 independent analog input channels
  • Designed for 100 Ohm (Pt100) RTD sensors
  • Supports 3-wire RTD configuration for accuracy
  • High-resolution A/D conversion (approx. 12-bit)
  • Operates on 24 VDC power supply
  • LinkNet communication for distributed I/O systems
  • Built-in diagnostics and reference voltage check
  • Wide operating temperature range (-40°C to +85°C)
  • High input impedance (~33 kΩ) for signal stability

⚙️ Applications

  • Gas and steam turbine control systems
  • Power generation plants
  • Oil & gas process monitoring
  • Industrial temperature monitoring systems
  • Marine and offshore automation
  • Distributed control systems (DCS)

? Notes

  • Part Number: 9905-970
  • Manufacturer: Woodward
  • Input Type: 100 Ω RTD (Pt100)
  • Network: LinkNet distributed I/O system
  • Typically used with MicroNet / turbine controllers
  • Status: Legacy/obsolete product but still available for spare and replacement use

? Simple Explanation

? This module reads temperature from up to 6 sensors and sends that data to a control system, helping machines like turbines run safely and efficiently.
