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.
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.

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
• Digital I/O watchdogs detect computer or application errors and
• Change detection triggers your application and returns I/O data
• 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.
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.
