Products Description
The Woodward 8440-2050 Genset Controller Module is a high-precision solution for managing industrial generator sets, offering advanced monitoring and control capabilities. Featuring 16-bit analog input resolution, it ensures accurate measurement and reliable performance across a broad operating range. The module accommodates current settings from 1 to 32,000 A and voltage settings from 50 to 650,000 Vac, providing exceptional flexibility for diverse power applications. Each input path maintains a high impedance of 2.0 MΩ, minimizing loading effects and preserving signal integrity. Designed for both 50 Hz and 60 Hz systems (40–85 Hz), it delivers consistent and precise measurement under varied operating conditions. Powered by 12/24 VDC (8–40 VDC), the 8440-2050 offers robust performance and seamless integration into industrial genset control systems.
