The Woodward 9907-175 is a load-sharing module designed to integrate Woodward power accessories and distribute loads between Caterpillar speed controllers and engines controlled by Woodward components. Designed to work with Caterpillar digital speed control with pulse width modulation (PWM) inputs, the module has a power range of 18 to 32 volts /DC, has approximately 5 watts of power, and has undervoltage and overvoltage protection in excess of 80 volts /DC, and can even withstand negative 32 volts /DC reverse voltage.

The three-phase PT input of the 9907-175 module is suitable for operation at 100 to 240 volts AC, and its PT input loads are 1.5 to 1.7 VA per phase at 240 V/AC and 0.4 to 0.5 VA per phase at 120 V/AC.
