Overview and Applications
The NI USB-6509 is a portable, industrial data acquisition device with
96 channels of digital I/O. It is compatible with TTL, CMOS, and 5 V
digital logic levels. You can individually configure each port of eight lines
for input or output. You can drive external digital devices, such as solid-
state relays (SSRs), with current up to 24 mA per line using power
available over USB. In bus-powered mode, the USB-6509 can source up to
215 mA total across all digital output lines. Use the optional 12 VDC
power supply for additional sourcing current. A USB-6509 is ideal for
general-purpose data acquisition applications as well as industrial control
and automated manufacturing test. With high-current drive, you can
connect the digital I/O device directly to a wide array of 5 V electronic
devices, sensors, and actuators.
Industrial digital I/O devices are designed to incorporate the latest
hardware technologies for applications requiring ease of use, high
reliability, and performance. The USB-6509 takes advantage of NI-DAQmx
measurement services software to speed up application development
with features such as the DAQ Assistant, automatic code generation,
and high-performance multithreaded streaming technology.
• Programmable power-up states provide safe operation when
connected to pumps/valves/motors/relays
• Digital I/O watchdogs detect computer or application crashes and
ensure safe recovery
• Change-detection triggers your application and performs a read
operation after a digital event with minimal processor usage
• Programmable input filters eliminate glitches/spikes and remove noise
Glitch-Free Startup with Programmable
Power-Up States
Using programmable power-up states, you can configure the initial
USB-6509 output states in software to ensure consistent, reliable
operation when connected to industrial actuators such as pumps, valves,
motors, and relays. A USB-6509 holds these output states after receiving
power, so your computer can boot and your software application can
begin running. Programmable power-up states are glitch-free, meaning
the outputs never go through an incorrect state during power up.
You can configure each digital line as high-impedance-input, high-output,
or low-output. A USB-6509 stores the settings in onboard nonvolatile
memory and implements the power-up states instantaneously after power
is applied to the device.
