Description
Woodward 9905-971 is a LON-based LinkNet remote discrete input module with 16 channels and network address 7 in the documented 723PLUS LinkNet configuration. The module reports open or closed contact states to the connected controller over the LinkNet I/O network.
Woodward states that LinkNet modules connect through shielded twisted-pair wiring and use rotary switches for the configured network address. Product Change Notification 06988 identifies 9905-971 as an obsolete 24 VDC module subject to final production stop and inactive ERP status from January 2024.

- Remote acquisition of sixteen 24 VDC discrete input channels
- Monitoring of open or closed field-contact states
- Handling of non-time-critical sequence and status inputs
- Distributed discrete input collection on a first-generation LON LinkNet network
- Reporting LinkNet channel states to the documented 723PLUS control application
9905-971 is a remote discrete-input component, not a complete control system. Complete operation requires the documented 723PLUS application, LON LinkNet wiring, configured network address, field contacts, and commissioned channel verification.
System: Manual 26043 documents 9905-971 on a 723PLUS LON #1 LinkNet network at address 7. Woodward does not describe the newer LinkNet HT family as a direct plug-and-play replacement for this module.
Network integration: Use shielded twisted-pair LinkNet wiring and set the two rotary address switches to the value defined by the application program; Manual 26043 documents address 7 for 9905-971.
Lifecycle: PCN 06988 identifies 9905-971 as obsolete and inactive in ERP from January 2024. Woodward does not state that LinkNet HT is a direct plug-and-play replacement.

Technical notes
Confirm the 9905-971 marking, 24 VDC input function, and controller application before replacement. Set the two rotary switches to the network address defined by the application program; the documented address for this module is 7. Use shielded twisted-pair LinkNet wiring and the approved network geometry from the current Woodward manual. Power-cycle as required after changing the hardware address because LinkNet nodes read their switch address at power-up. Verify channel state reporting and network communication before returning the control system to service.
