723PLUS Digital Control
Application
The 723PLUS Digital Control can be programmed to suit applications requiring two magnetic pickups (MPUs) or proximity switches (e.g. for torsional filtering) as the hardware includes two speed inputs. It also includes four analog inputs, three analog outputs, eight discrete inputs and three discrete outputs, all of which can be programmed to satisfy the application. The control can be used in load sharing systems as it contains circuitry and connections to support this.
The two LON® * channels can be used to support Woodward LonTalk® * or LinkNet® input/output nodes control functions. *—LON and LonTalk are trademarks of Echelon Corporation.
The 723PLUS control (Figure 1-1) consists of a single printed circuit board in a sheet-metal chassis. Connections are via three terminal strips and three 9-pin subminiature D connectors.
