As part of the Woodward LinkNet family, this module enables MicroNet and NetCon control systems to interface directly with field-actuated devices, control valves, positioners, and external indicators over standard 4–20 mA current loops. Operating as a networked I\/O node, the 9905-972 offloads signal-processing tasks, reduces field wiring complexity, and ensures fast, deterministic command execution. Built with a rugged enclosure for demanding industrial environments, the module features an approximate shipping weight of \u003cstrong\u003e0.45 kg (1.0 lbs)\u003c\/strong\u003e and delivers precise dynamic response across operating temperatures from 0°C to 55°C.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable border=\"1\" style=\"width: 100%;
