Low-Cost Industrial Digital I/O – 5 V TTL/CMOS Overview NI 6509 industrial digital I/O interfaces are 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 interface directly to a wide array of 5 V electronic devices, sensors, and actuators. These interfaces 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 are designed to incorporate the latest hardware technologies and provide innovative features for applications requiring ease of use, high reliability, and performance. NI 6509 interfaces take advantage of NI-DAQmx measurement services software to speed up application development with many helpful features including the 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, 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...

Figure 3. NI PCIe-6509 Digital I/O Circuitry 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,...

Input high-Z (default), output 1 or 0 Input pulled up or down (software-selectable), output 1 or 0 Data transfers 100-pin female 0.050 series SCSI I/O connector Pull resistor (NI PCIe-6509 only) Pull-up resistor Pull-down resistor Input voltage protection (NI PCIe-6509 only) Digital Logic Levels (NI PCI/PXI-6509) Input Signals The maximum input logic high and output logic high voltages assume a Vcc supply voltage of 5.0 V. Given a Vcc supply voltage of 5.0 V, the absolute maximum voltage rating for each I/O line is –0.5 V to 5.5 V with respect to GND. Level Input logic high voltage (VIH) 2...

Output Signals Level High-level output current (IOH) Low-level output current (IOL) Output voltage (Vout) Output high voltage (VOH), at –24 mA 3.4 V — Output low voltage (VOL), at 24 mA The total current sinking/sourcing from one port cannot exceed 100 mA. Without the disk drive power connector installed, the +5 V supply and the DIO lines share the same power source. In this case, use the following equation to determine the current available at the +5 V terminal. In the equation, I DIO is the total current sourced on all DIO lines. I+5V = 1.2 A − IDIO With the disk drive power connector...
