The National Instruments cFP-PWM-520 is a versatile pulse-width modulation output module for Compact FieldPoint that you can use to control the power of many DC-powered devices. By pulsing the input voltage and varying the duty cycle, you can perform analog control on many DC devices. The NI cFP-PWM-520 is commonly used to efficiently control power such as the speed of a DC servo motor, the intensity of a light bulb, or the heat output of an industrial heater.

You can configure the output period for each cFP-PWM-520 channel to vary from 1 ms to 65.5 in 1 ms increments. You then programmatically set the duty cycle for each channel. The duty cycle is the percentage of the output period when output is high. You can set the duty cycle for 0 to 100 percent with 12-bit resolution (4,096 settings). Each output channel is an optically isolated sourcing output with overcurrent protection. The outputs are compatible with voltages from 10 to 30 VDC, or 4.5 to 5.5 VDC, and each output can drive up to 1 A.
