Product Description

Part 8280-418 is a single-engine marine control in the Woodward 723PLUS series. There are several similar 723PLUS controls, this one is for single-engine, single-propeller (variable or fixed pitch) propulsion systems. It is a low-voltage, low-speed model. The 8280-418 is designed for use with low-speed diesel reciprocating engines and has a power supply that is rated for 18-40 Vdc. For the medium- and high-speed versions of this control, see model number 8280-419.


This Woodward 723PLUS control can be used with either magnetic pickups (MPUs) or proximity switches, so it can be used in applications with flexible couplings. There are two inputs that both support either speed sensing option. The 8280-418 also has inputs for remote speed reference, lube oil pressure, water pressure, and air manifold pressure.


The 8280-418 has three communication ports. One of these ports can be used to interface to Watch Window (PC-based software) or a handheld programmer, while the other ports can be configured for RS-232, RS-422, or RS-485 communications. Watch Window and the handheld programmer are both Woodward accessories. Another optional PC-based interface that can be used with the 8280-418, is the 723PLUS Marine SEP Control View software. Woodward 723PLUS Product Manual 02880 has more information on all these options.


The Woodward 8280-418 control is CSA Certified and CE Compliant. It also complies with EN50081-2 and EN50082-2 requirements provided it is put into service per the instructions outlined in the product manual.
