Pulse-Width Modulation Output Module for Compact FieldPoint NI cFP-PWM-520 • 8 outputs • 5, 12, and 24 VDC • 1 A per channel, maximum • 1 kHz max frequency • Overcurrent protection on outputs • 2,300 Vrms bank isolation for transient overvoltage protection • Hot-swappable with autoconfiguration • -40 to 70 °C operating range Output Module Channels cFP-PWM-520 8 Output Voltages 5 VDC or 10 to 30 VDC Output Frequency Up to 1 kHz Output Output Current Duty Cycle (see Specifications) 0 to 100% 1A Overview 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. It includes onboard diagnostics to ensure trouble-free installation and maintenance. Pulse-Width Modulation Output 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. Isolation The cFP-PWM-520 features optical bank isolation with 2,300 Vrms of breakdown isolation. This Compact FieldPoint module does not have channel-to-channel isolation. Field I/O Connections Compact FieldPoint modules include a built-in power distribution bus that provides multiple power connections on the module. A field-wired power supply connected to the voltage (V) and common (C) terminals is internally connected to a power distribution bus that offers additional breakout terminals for voltage supply (VSUP) and common (COM). These terminals deliver a convenient way to distribute power to field devices that require external power. The cFP-PWM-520 has: • 8 pulse-width modulation digital output terminals (VOUT) • 16 common terminals (COM) • 8 power connections to power field devices (VSUP) Pulse-Width Modulation Output Module for Compact FieldPoint C V VSUP Protected Sourcing Output 5 to 30 VDC External Power Supply + VOUT COM Load – COM cFP-PWM-520 Wiring Schematic for the cFP-PWM-520 Ordering Information NI cFP-PWM-520 ................................................................777318-520 Recommended Compact FieldPoint System Products NI cFP-2120 ......................................................................777317-2120 NI cFP-BP-4 ............................................................................778617-04 NI cFP-CB-1............................................................................778618-01 NI PS-5 power supply............................................................778805-90 NI Developer Suite Professional Control Edition ....................777906-03 BUY NOW!
