701, 721 and 723 Digital Control
Obsolete
Support and modernisation enquiries for installed Woodward 701, 721 and 723 digital controls, including 723PLUS. Repair and retrofit routes are assessed case by case.
Description
Product overview
Identify the installed control before deciding the next move.
The Woodward 701, 721 and 723 digital controls are legacy installed controls; the 723 family also includes the 723PLUS. The installed part number, application software and connected interfaces determine what can be repaired, exchanged or modernised. TURNER ECS can review that system context before recommending a route for an existing asset.
The 723PLUS documentation supplied below describes reciprocating-engine applications in power generation, marine propulsion and industry. Its specifications must not be assumed to apply to every 701, 721 or standard 723 installation.
