Product Description
Part 8280-219 is a Woodward speed controller. This controller is a low voltage, PG replacement model in the company’s 723 Speed Control line. The 8280-219 model is intended for marine applications, where it can control load and speed of medium- and high-speed diesel engines. It is suitable for dual-engine applications where mechanical load sharing is required.
As a low voltage model, this 723 Speed Control has an input power rating of 18 to 40 Vdc (24 or 32 Vdc nominal). To ensure safe and accurate unit functioning, an operating temperature range of –40 to +70 °C with no more than 95% humidity (at +20 to +55 °C) must be maintained, though temperatures during storage can safely fall in the –55 to + 105 °C range.
The 8280-219 comes with integrated diagnostic tests to monitor the control’s baseline power supply, processor, and memories. 723 Control set points are stored in the control’s permanent memory, removing the need for an external power supply to retain this data. Set points are configured using a menu-driven handheld programmer (Woodward part 9907-205, sold separately), which connects to the unit via a serial port.
Along with three serial ports, the 8280-219 has several discrete inputs, analog I/Os, load-sharing lines, relay outputs, two LON channels, and two alarm outputs. Information on the control’s I/Os can be found in Woodward 723 Digital Control Product Specification 02759B.
