Product Description

The PXIe-2531 is a 1-wire 4×128 matrix switch. It utilizes high-speed Reed Relays, which offer significantly faster switching speeds than traditional electromechanical armature relays, making it ideal for high-throughput manufacturing and functional test environments.

Product Parameters

The PXIe-2531 is optimized for density and speed. Below are the key technical parameters:

Product Advantages

• High Throughput: With a switching time of just 0.25 ms, this module is significantly faster than standard relay modules, drastically reducing total test time.

• Extreme Density: It packs 512 crosspoints into a single PXI Express slot, allowing for large matrix configurations without consuming excessive chassis space.

• Onboard Relay Counting: The module tracks relay cycles automatically, allowing for predictive maintenance and helping you avoid unexpected downtime by replacing the module before relay failure.

• PXI Express Integration: Leverages the PXI Express bus for faster communication with the controller and advanced triggering capabilities through the PXI backplane.

• Scalability: Multiple PXIe-2531 modules can be expanded into larger matrices (e.g., 4×256 or 8×128) using terminal blocks or custom cabling.

Key Considerations (Precautions)

• Voltage Limits: This module is rated for Low Voltage (60 VDC) only. Applying mains voltage or high-voltage signals will damage the reed relays and potentially the entire PXIe chassis.

• Relay Protection: Reed relays are sensitive to capacitive and inductive loads. If switching long cables or reactive loads, ensure you use current-limiting resistors to prevent “arcing” that can weld the contacts shut.

• Cold Switching: To maximize the life of the relays, it is recommended to perform “cold switching” (turning off the signal source before opening or closing the relay) whenever possible.

• Terminal Blocks: Due to the high-density 200-pin LFH connector, it is highly recommended to use the TB-2643 terminal block for easier wiring.

Product Applications

1. Consumer Electronics Testing: Routing signals between a DUT (like a smartphone or tablet) and various instruments (DMMs, Oscilloscopes).

2. Semiconductor Functional Test: Connecting multiple test pins of an integrated circuit to a shared set of measurement hardware.

3. Automotive ECU Testing: Managing hundreds of signal paths in Electronic Control Unit (ECU) validation systems.

4. Hardware-in-the-Loop (HIL): Simulating sensor inputs and fault conditions by routing signals dynamically.
