Product Description

The NI PCI-6503 is a 24-channel, 5 V TTL/CMOS digital I/O interface for the PCI bus. It is designed to provide a straightforward and reliable solution for a variety of digital input and output tasks. The device uses a programmable peripheral interface (PPI), making it a simple, cost-effective way to integrate digital I/O capabilities into a PC-based system.

Product Specifications

• Bus Connector: PCI
• Channels: 24 digital I/O channels, configurable in groups of 8.
• Logic Levels: Compatible with 5 V TTL/CMOS logic.
• Digital Input Voltage Range: 0 V to 5 V
• Digital Output Voltage Range: 0 V to 5 V
• Current Drive: 2.4 mA
• Interface: Uses a programmable peripheral interface (PPI).
• Connector: 50-pin ribbon cable connector.

Product Advantages

• Simplicity and Cost-Effectiveness: The PCI-6503 is a simple, no-frills digital I/O card. This makes it a very affordable option for applications that don’t require high-speed or advanced features like hardware timing.
• Versatility: The 24 channels can be configured in groups of 8 for input or output, providing flexibility for different applications.
• Plug-and-Play: The device is designed for easy installation and is fully supported by NI software, such as NI-DAQmx and LabVIEW, which simplifies configuration and programming.
• TTL/CMOS Compatibility: The 5 V logic level compatibility makes it easy to interface with a wide variety of standard digital components and circuits.

Product Applications

The NI PCI-6503 is a good fit for applications that require basic digital I/O control and monitoring.

• Lab Automation: Controlling relays, switches, and other simple devices in a laboratory setting.
• Educational Environments: Teaching students about digital logic, control systems, and data acquisition.
• Simple Control Systems: Providing digital inputs and outputs for non-time-critical industrial control or test and measurement systems.
• Logic Signal Monitoring: Reading the states of digital switches, sensors, and other logic-level signals.

Precautions

To ensure safe and reliable use of the NI PCI-6503, be aware of the following:

• Voltage Limits: Do not exceed the 0 to 5 V voltage limits on the digital I/O lines. Connecting signals with higher voltages can permanently damage the device.
• Current Drive: The current drive is limited to 2.4 mA. Do not try to drive loads that require more current than this, as it can damage the output channels.
• ESD Precautions: The device contains sensitive electronic components. Always handle the card in a static-safe environment and follow proper electrostatic discharge (ESD) procedures to prevent damage.
• Cable and Connector: Use a compatible 50-pin ribbon cable and breakout board to ensure a reliable connection to your external circuits.
