Woodward 9905-970 Rev K LinkNet 6-Channel RTD Input Module

The 9905-970 (Model: 9905-970) is a specialized temperature acquisition module within Woodward’s LinkNet distributed I/O family. Specifically designed for precision monitoring in turbine and engine control environments, this module interfaces directly with $100\Omega$ Platinum RTDs (Resistance Temperature Detectors). The 9905-970 (Part Number: 9905-970) Revision K features enhanced signal conditioning to provide highly accurate temperature data back to a central MicroNet or Atlas control system via the high-speed LinkNet serial bus.

Unlike general-purpose speed controllers, the 9905-970 (Model: 9905-970) is engineered to handle the low-voltage resistance signals inherent to RTDs, providing 6 independent channels of linearized temperature data. By distributing these modules close to the turbine or engine, users can significantly reduce the long runs of expensive extension wire and minimize the potential for electromagnetic interference (EMI) that can degrade temperature readings. This module is essential for monitoring critical thermal parameters such as bearing temperatures, exhaust gas temperatures (EGT), and lubricant states in mission-critical power generation and oil & gas applications.
