Woodward 8280-412 723PLUS DSLC Digital Load Sharing Controller

Product Overview

The Woodward 8280-412 is a low-voltage digital speed and load sharing controller from the 723PLUS DSLC platform. It is engineered for precise control of reciprocating engines driving generator sets operating in parallel. By combining high-resolution speed regulation with stable real-time load sharing, this controller ensures reliable performance in demanding power generation and marine environments.

Built on a 32-bit microprocessor architecture, the module supports scalable system design through LinkNet expansion nodes, allowing additional discrete I/O and temperature monitoring without redesigning the core control system.

Core Functions

The 8280-412 provides closed-loop digital speed control while coordinating active load distribution between multiple generator sets. It maintains frequency stability during load transients and supports seamless parallel operation across multiple engines.

Designed for low-voltage DC systems, the controller operates reliably in installations using nominal 24 VDC or 32 VDC power supplies.
