Functionality

1.Multi-Channel Signal Switching：Provides 32 independent SPDT relay channels for flexible switching between multiple signals, enabling signal routing and distribution.

2.Signal Connect/Disconnect Control：Each channel can independently control signal continuity, supporting Normally Open, Normally Closed, or switching modes to meet different test requirements.

3.Multi-Channel Scanning & Acquisition：Works with data acquisition cards or multimeters to achieve automatic scanning and measurement of multi-channel sensor signals, voltage, and current.

4.Digital I/O Control：Used for switching digital logic levels to control external relays, indicator lights, solenoid valves, and other low-voltage devices.

5.Test System Channel Expansion：Acts as a signal hub in automated test systems to expand the number of test channels and improve test efficiency.

Key Features

High-Density Channels: Provides 32 independent SPDT relays, ideal for large-scale signal scanning and distribution.

Low to Medium Power Switching: Supports 30VDC / 125VAC voltage and 1A (DC) / 0.5A (AC) current, suitable for digital I/O, sensor signals, and low-power load control.

Low Path Resistance: Contact resistance ≤ 60mΩ, channel resistance ≤ 300mΩ, ensuring transmission accuracy for weak signals.

Fast Operation: Pickup time ≤ 3ms, release time ≤ 3ms for quick response.

Traditional PXI Architecture: Compatible with PXI backplanes, suitable for upgrading or expanding existing PXI systems.

High-Density Interface: Uses a SCSI100 connector to save panel space.

Custom Design

The original design intention of the PXI2913 is to act as a versatile, high-density signal routing node. Its purpose is to help engineers reliably perform the switching, distribution, and ON/OFF control of numerous general-purpose signals via software control within complex automated test systems.
