WOODWARD 5466-425 Programmable Automation Controller (PAC)

WOODWARD 5466-425 Programmable Automation Controller (PAC)

Product Overview

WOODWARD 5466-425 is Woodward's next-generation programmable automation controller designed specifically for critical industrial control applications. As the core component of the MicroNet TMR (Triple Modular Redundancy) series, this controller provides highly reliable safety critical control in fields such as power generation, oil and gas, and ship propulsion. It is particularly suitable for the protection and control of gas turbines, steam turbines, and large rotating equipment.
