Woodward 5421-112 Driver Amplifier Board Assembly

Description

The Woodward 5421-112 Driver Amplifier Board Assembly is a high-performance industrial control component designed for engine speed regulation and actuation control. It operates in a wide temperature range of -40 degrees Celsius to 85 degrees Celsius, with a 9-30 Vdc power input that includes reverse polarity protection for enhanced durability in harsh environments. Key electrical specifications include a pulse width modulation actuation output with a 6A maximum rating, and an auxiliary output with a 200 mA maximum limit. It meets strict EMI immunity standards, with resistance to 100 V/m from 200 to 1000 MHz, and can withstand vibration of 6 Gs from 40 Hz to 2000 Hz, plus shock of 20 Gs at 45 Hz. Calibration requires a dedicated interface adapter and software, and it uses a Deutsch housing with two 12-way sealed connectors, intended for installation in engine compartments (not directly on engines), with a total weight of 0.27 kg (0.6 lbs). Core features include high-precision fuel flow metering, a single moving part for reliable performance, fully electric drive, on-board driver, fast dynamic response, a rugged self-cleaning valve, compliance with ANSI B16.104 Class III, support for digital and/or 4-20mA air shutoff analog signal interfaces, discrete fault output and independent shutdown, and certification for use in hazardous locations.
