Product Description

The NI TB-2715 is a front-panel terminal block designed for use with specific NI PXI digital I/O modules, particularly those with a 68-pin VHDCI connector. This accessory simplifies the process of connecting external digital signals to your PXI system by breaking out the high-density connector into easy-to-use screw terminals.

Product Specifications

The TB-2715 is a passive terminal block, and its key features are related to its physical and electrical connectivity.

• Connector: It features a 68-pin VHDCI (Very High Density Cable Interconnect) connector, which plugs directly into a compatible PXI module.
• Terminals: It provides 68 screw terminals for individual wire connections. Each terminal corresponds to a specific pin on the PXI digital I/O module.
• Voltage Rating: The terminals have a voltage rating of 60 VDC.
• Form Factor: The TB-2715 is designed to mount directly onto the front panel of a PXI module.

Product Advantages

• Simplified Wiring: The main advantage of the TB-2715 is that it makes connecting and disconnecting digital signals to a PXI system much easier. Instead of dealing with a high-density cable, you can use simple screw terminals for a secure, direct connection.
• Robust Connections: The screw terminals provide a reliable and durable connection, which is crucial for preventing intermittent faults and ensuring accurate data transmission in a test or control system.
• Compatibility: The TB-2715 is a standard accessory for many NI PXI digital I/O cards, making it a versatile and reusable component across different projects.

Product Applications

The TB-2715 is used in any application that requires connecting external digital signals to a PXI digital I/O module. This includes:

• Automated Test Equipment (ATE): Integrating digital signals from a unit under test (UUT) into a PXI-based ATE system.
• Industrial Control: Connecting digital inputs and outputs from sensors, switches, and relays to a PXI controller for automated control applications.
• Hardware-in-the-Loop (HIL) Simulation: Providing a straightforward way to interface digital I/O signals in a real-time HIL simulation system.

Precautions

To ensure safe and reliable use of the TB-2715, keep the following in mind:

• Pinout Awareness: Always refer to the user manual of your specific PXI digital I/O module to understand the correct pinout. The function of each terminal on the TB-2715 is determined by the connected module.
• Voltage Limits: Do not exceed the 60 VDC voltage rating of the terminal block, as this could damage your hardware.
• ESD Precautions: Follow proper electrostatic discharge (ESD) precautions when handling the terminal block and the PXI module to prevent damage to sensitive electronics.
• No Hot-Swapping: Do not connect or disconnect the TB-2715 from the PXI module while the system is powered on. Always power down the PXI chassis first to avoid hardware damage.
