1. Product Title

Woodward DPG‑2223‑002‑ Digital Turbine Governor Controller Module

2. Product Overview

DPG‑2223‑002 is a microprocessor‑based digital governor controller for single‑valve steam turbines, gas turbines and engine‑generator sets in power‑generation applications. It delivers closed‑loop speed, load and split‑range actuation control, with built‑in overspeed protection and fault‑detection logic. Integrated front‑panel 2‑line LCD display and keypad support local parameter configuration, real‑time monitoring and fault review. Watchdog IOLOCK safety function forces outputs to safe de‑energized state upon internal hardware failure to protect prime‑mover equipment. It supports Modbus communication for SCADA host connection, widely used as critical spare for industrial power‑plant and co‑generation turbine control cabinets.
