Original Woodward 2301D digital governor 8273‑140, 24VDC speed and load‑sharing controller for parallel generator sets ordinary location application.

Product Overview

8273‑140 is 2301D series digital load‑sharing and speed controller manufactured by Woodward, designed for ordinary non‑hazardous location generator set control. Based on microprocessor hardware, it realizes prime‑mover precise speed regulation, isochronous control and multi‑genset parallel load sharing, receives magnetic pickup speed signal and load feedback signal, outputs drive signal to fuel actuator. It supports parameter configuration, fault monitoring and alarm output, ensures stable frequency and balanced load distribution for multiple parallel generator units. Rugged panel‑mount hardware fits continuous operation for power‑plant, marine and industrial backup power cabinets. Widely used as maintenance spare part for diesel and gas generator control systems.

Key Features

• Microprocessor‑based digital algorithm, realizes high‑precision speed regulation and multi‑generator load‑sharing control
• Supports isochronous and droop control modes for genset standalone and parallel operation scenarios
• Accepts magnetic pickup MPU speed input signal for prime‑mover rotational speed measurement
• Configurable analog and discrete I/O for actuator driving, alarm output and external interlock signal
• Built‑in fault diagnosis function, monitors power supply and signal abnormal status
• Front‑panel indicator lights for operating status and fault prompt for on‑site troubleshooting

• Panel‑mount housing for cabinet installation, industrial‑grade hardware adapts to generator‑site vibration environment
