Woodward 9905-971 LinkNet 16-Channel Discrete Input Module
The 9905-971 (Model: 9905-971) is a high-density distributed I/O module designed for Woodward’s LinkNet control architecture. As a specialized component for industrial turbine and engine control systems, this module provides 16 independent discrete input channels. The 9905-971 (Part Number: 9905-971) Revision J is engineered to interface field-side switch contacts, relays, and digital sensors directly with Woodward’s MicroNet or Atlas control platforms via the high-speed LinkNet serial bus.
By utilizing the 9905-971 (Model: 9905-971), engineers can implement a distributed control strategy, placing the digital acquisition hardware close to the machinery. This drastically reduces the volume of field wiring required to reach the central control room. Each channel is designed to sense 24 VDC logic states, making it ideal for monitoring critical status signals such as emergency stop buttons, oil pressure switches, and valve limit switches. The module's robust optical isolation ensures that electrical noise or surges from the field do not reach the sensitive logic of the main control CPU.
