Digital I/O Static DIO on NI USB-6509 Devices You can use each of the NI USB-6509 DIO lines as a static digital input (DI) or digital output (DO) line. You can use static DIO lines to monitor or control digital signals. Each DIO port can be configured as a DI or DO port. All samples of static DI lines and updates of DO lines are software-timed. Digital I/O Circuitry The NI USB-6509 provides 96 lines of bidirectional DIO signals, P<0..11>.<0..7>. You can configure the direction as input or ou

The NI USB-6509 has a current-sense circuit on VBUS (USB power rail). If the output channels source more than the specified current, the current is limited. The two following occurrences indicate an overcurrent condition: � The inputs/outputs are disabled � The LED on the back panel is blinking If you want to increase the current drive capacity on the NI USB-6509, you can use an optional external +12 VDC power supply. For more information, refer to the Optional +12 VDC Power Supply Installat

Protecting Inductive Loads When inductive loads are connected to outputs, a large counter-electromotive force may occur at switching time because of the energy stored in the inductive load. These flyback voltages can damage the outputs and/or the power supply. To limit these flyback voltages at the inductive load, install a flyback diode across the inductive load. For best results, mount the flyback diode within 18 inches of the load. Figure 12 shows an example of using an external flyback

+5 V Power Available at I/O Connector Pins 49 and 99 supply +5 V power to the I/O connector. The power drawn from these two pins shares the power consumption with the transceivers. The I/O connector power has a fuse for overcurrent protection. This fuse is not customer replaceable. If the fuse is blown, return the device to NI for repair. Caution The power pins, +5V and GND, connect to the computer power supply and are not isolated. Do not connect a +5V power pin directly to GND or connect
