4/15/2004 - Engineers now can use National Instruments three new general-purpose PXI switch modules to maximize relay density in a single PXI chassis for reduced system costs and smaller test system footprints. The modules are part of a growing line of new switches from NI that give engineers more than 70 switch configurations to choose from for their automated test systems.
The new switches are ideal for a variety of applications and industries including in-circuit testing in electronics and semiconductor applications; low-frequency signal switching in telecommunications applications; and low-current, high-channel ECU testing in automotive applications.
The NI PXI-2568 switch module is a 31-channel SPST (Form A) relay module. It features independent, latching armature relays with very low on-resistance and low thermal offsets. The module can switch up to 2 A at 30 VDC/30 VAC or up to 150 VDC/150 VAC at lower currents. With an efficient coupling of density and power, the PXI-2568 module is ideal for medium-channel-count control or routing applications.
The NI PXI-2569 switch module is a 100-channel SPST (Form A) relay module. With 100 channels in a single 3U PXI module, it offers incredible density for high-channel automated test equipment (ATE) applications. A chassis full of PXI-2569 modules can offer 1,700 relay channels at up to 100 VDC/100 VAC or 1 A.
Finally, the NI PXI-2570 is a 40-channel SPDT (Form C) relay module. At 100 VDC/100 VAC or 1 A of switching power, the module is ideal for high-channel control systems or routing ATE loads. Each relay contains a normally open, normally closed and common terminal.
All NI switch hardware seamlessly integrates with the NI LabVIEW graphical development environment, NI Switch Executive switch configuration management software and NI TestStand test management software. Engineers can use NI Switch Executive to program, validate and maintain their switch system. The modules ship with NI-SWITCH driver software for module-level control and debugging.
NI designed each of the new switch modules with highly accelerated life testing and performed rigorous environmental testing to ensure quality. Each module comes with CE and UL certification for their respective current and voltage specifications.
