Table 1. NI 6509 Specifications Overview
Overview and Applications
NI 6509 devices are industrial 96-channel digital I/O interfaces for PCI
and PXI systems. They are compatible with TTL, CMOS, and 5 V digital
logic levels. An NI 6509 has 96 bidirectional digital I/O lines with high-
current-drive capabilities (24 mA), and is completely jumper-free. With
an NI 6509, you can input and output at 5 VDC digital levels and directly
drive external digital devices such as solid-state relays (SSRs) with
current up to 24 mA per channel. You can configure each port individually
for input or output, and no external power supply is required for outputs.
An NI 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 module directly to
a wide array of 5 V electronic devices, sensors, and actuators.
These devices offer superior features and high value for industrial
control and manufacturing test applications such as factory automation,
embedded machine control, and production line verification. They
have been designed to incorporate the latest hardware technologies
and provide innovative features for applications requiring ease of use,
high reliability, and performance. NI 6509 devices take advantage of
NI-DAQmx measurement services software (7.1 or later) to speed up
application development with many helpful features including the DAQ
Assistant, automatic code generation, and high-performance multithreaded
streaming technology.
Hardware
High-Reliability Industrial Feature Set
NI 6509 devices offer a set of high-reliability features designed to
automate even the most demanding applications:
• Programmable power-up states provide safe operation when
connected to pumps, valves, motors, and relays
• Digital I/O watchdogs detect computer or application errors and
ensure safe recovery
• Change detection triggers your application and returns I/O data
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
With programmable power-up states, you can configure the initial
NI 6509 output states in software to ensure glitch-free operations when
connected to industrial actuators such as pumps, valves, motors, and
relays. An NI 6509 holds these I/O states after receiving power, so your
computer can boot and your software application can begin running. The
programmable power-up states are glitch-free, meaning the outputs
never go through an incorrect state during power up.
You can configure digital lines as high-impedance input, high output,
or low output. The digital I/O device stores the settings in onboard
nonvolatile memory and implements the power-up states automatically
after power is applied to the device.

Detect and Recover with Digital I/O Watchdogs
NI digital I/O watchdogs provide protection against a wide variety
of fault conditions:
• Computer crash – total OS crash
• Application crash – software application ceases to respond
• Driver crash – device driver ceases to respond
• PCI bus failure – communications cease to respond
With watchdogs, the digital outputs go to a safe state when a fault
condition is detected and the watchdog timer expires for safe recovery.
Watchdogs are important whenever the device is connected to actuators
such as pumps, valves, motors, and relays. The digital I/O device monitors
the software application and, if it fails to respond within the time limit,
automatically sets the output lines to a user-defined safe state. The device
remains in the watchdog state until the watchdog timer is disarmed by
the application and new I/O values are written, an NI 6509 is reset, or
the computer is restarted.
input lines, you can use programmable input filters in combination with
change detection to eliminate spurious change detection events caused
by noise or glitches. NI-DAQmx also includes multithreaded streaming
technology so digital change detection events can occur independently
of other data acquisition activities such as analog input or output events.
Eliminate Noise with Programmable Input Filters
Programmable input filters remove noise, glitches, and spikes on inputs,
as well as provide debouncing for digital switches and relays. This is
important for applications in noisy industrial environments to prevent
false readings caused by noise. You can configure the programmable
input filter for each digital line by setting the filter time in seconds. Any
digital noise, glitch, or spike that is shorter than half of the specified
filter time is blocked by the digital I/O device, preventing invalid readings
and false triggers for change detection events.
Software
NI-DAQmx Software Technology
NI 6509 devices require NI-DAQmx 7.1 or later. NI-DAQmx software,
included free with an NI 6509, is available for download from
ni.com/downloads.
With NI-DAQmx 7.1 or later, you can use your
NI digital I/O device in LabVIEW, ANSI C, Microsoft Visual C++, and the
Microsoft .NET languages C# and Visual Basic .NET.
With NI-DAQmx technology, you have access to the full functionality
and state-of-the-art hardware technology of your NI 6509 digital I/O
devices. NI-DAQmx technology speeds up your development with many
features such as automatic code generation to make configuration and
programming easy. NI 6509 devices take full advantage of key NI-DAQmx
Trigger Your Application with Change Detection
With change detection, you can automatically trigger your software
application to perform a digital read operation upon a digital change
of state. A digital change of state is defined as the rising edge (0 to 1
transition) or falling edge (1 to 0 transition) on one or more digital lines.
Using change detection, you can monitor for digital events with minimal
processor usage. No polling is necessary because the digital I/O device
generates an interrupt to automatically wake up your application.
Using NI-DAQmx software technology, an NI 6509 notifies the software
application when the event is detected, causing the application to
automatically perform a read operation. To minimize the effects of noisy

Digital I/O Connector
The 100-pin high-density SCSI connector on NI 6509 devices connects to
100-pin ribbon cable or shielded cables. For low-cost unshielded connectivity,
use the R1005050 ribbon cable with two CB-50LP or CB-50 connector
blocks (a CB-100 kit). For shielded connectivity, use the SH100-100-F
shielded digital I/O cable with the SCB-100 connector block.
You can individually program each 8-bit port on an NI 6509 to
be input or output. The maximum input logic high and output logic high
voltages assume a V

supply voltage of 5 V. The absolute maximum
voltage rating is -0.5 to +5.5 V with respect to GND. Pins 49 and 99 on
the I/O connector supply +5 V from the computer power supply through
a self-resetting fuse.
