Woodward 8440-1934 Perator Interface

The Woodward 8440-1934 Operator Interface is a versatile control module designed for seamless integration with industrial turbine and generator systems. It features freely scalable analog inputs, allowing precise monitoring and control of multiple process signals. The interface operates reliably across a wide input voltage range of 8 to 40 VDC (nominal 12/24 VDC), supporting stable operation under varied electrical conditions. Its measuring and setting frequency ranges from 40 to 85 Hz, accommodating both 50 Hz and 60 Hz systems for global compatibility. The module is powered directly by 12/24 VDC, ensuring consistent performance, and can withstand extreme storage temperatures from -22°F to 176°F, providing robust durability in harsh environments. Ideal for system operators requiring accurate, flexible, and resilient control, the 8440-1934 enhances both operational efficiency and equipment protection.
