Product Description
Speed control model 8280-466 offers a range of customizable parameters to make it suitable for a variety of applications. This controller is part of the 723PLUS Digital Speed Control series by Woodward and is one of the few controllers in the series that is designed for low-speed engines. The 8280-466 is a low voltage speed control (18 to 40 Vdc input voltage), designed for use with reciprocating engines rated at 130 rpm or less.
The 8280-466 offers load control features and has a speed bias input to support a DSLC Digital Synchronizer and Load Control. Three other versions of this DSLC-compatible control are also available (low voltage; high voltage; and high voltage, low speed), details of which can be found in the 723PLUS Digital Speed Control for Reciprocating Engines—DSLCTM Compatible Installation and Operation Manual Product Manual 02878.
There are several discrete and analog I/Os on this controller, including two-speed signal inputs which can handle magnetic pickups or proximity switches, depending on the needs of the application. The I/Os have varying levels of configurability, the details of which can be found in manual 02878.
Parameter setting and other 8280-466 configuration and monitoring are done via either a handheld programmer (a Woodward accessory, part 9907-205) or the PC-based Watch Window software. Both of these are menu-based, keeping the process straightforward and manageable regardless of the operator’s programming experience.
