I. Product Overview

WOODWARD 5460-735 is a classic 505 series microprocessor control platform, an integrated speed/load controller specifically designed for single/double actuator steam turbines. It is widely used in industrial steam turbines, compressors, pumps, and generator sets for speed control and protection, featuring high-precision regulation, full-function protection, and convenient programming capabilities. 

II. Core Functional Characteristics

Microprocessor Control: 32-bit processor, PID closed-loop regulation, high control accuracy and fast response.

Dual Actuator Drive: Supports single/double actuator (electro-hydraulic/ pneumatic) control.

Speed/Load Dual Modes: Switchable between speed control or load/power control.

Multi-level Protection: Comprehensive protection against overspeed, underspeed, vibration, shaft displacement, low oil pressure, high exhaust temperature, etc.

Dual Serial Ports: RS-232 + RS-422 independent ports, supporting programming, monitoring, and data acquisition.

PWM Synchronous Output: Built-in synchronizer, supporting automatic generator synchronization (frequency / phase / voltage matching).

Panel Programming: LCD + keys for local programming, allowing parameter configuration without a computer.

Hot Swap Compatibility: Supports online maintenance, reducing downtime.
