NI 6509 Specifications Overview National Instruments 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 VO 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. Each port can be individually configured 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. An NI 6509 offers superior features and high value for industrial control and manufacturing test applications such as factory automation, embedded machine control, and production line verification. NI 6509 devices have been designed from top to bottom to incorporate the latest hardware technologies and provide innovative features for applications requiring ease of use, high reliability, and performance. They take advantage of NI-DAQmx measurement services software (version 7.1 or higher) to speed up application development with many helpful features including DAQ Assistant, automatic code generation, and high-performance multithreaded streaming technology. 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/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 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. Each individual digital line can be configured as high-impedance input, high output, or low output. The digital I/O module stores the settings in onboard nonvolatile memory and implements the power-up states automatically after power is applied to the device.

Low-Cost Industrial Digital I/O – 5 V TTL/CMOS Voltage Supervisor Eliminate Noise with Programmable Input Filters Voltage Regulator Data Control Figure 1. NI 6509 Hardware Block Diagram Programmable input filters remove noise, glitches, and spikes on inputs, and also 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...

to jump-start your project • Use NI-DAQmx functions for jumper-free software configuration of all digital I/O features without hardware switches/jumpers • Develop your application with easy and open programming in LabVIEW, ANSI C, Microsoft Visual C++, C#, and Visual Basic .NET 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...
